Thermoplastic Elastomer (TPE), sometimes referred to as Thermoplastic Rubbers (TPR), are a class of copolymers or physical mixtures of polymers—typically a plastic and a rubber—that combine the properties of thermoplastics and elastomers. This unique combination allows TPEs to be processed like thermoplastics (via extrusion, paghubog ng iniksyon, blow molding, atbp.) while retaining the elasticity and flexibility of rubbers. Unlike traditional vulcanized rubbers, TPEs can be melted and reprocessed multiple times without significant loss of performance, making them more environmentally friendly and cost-effective. As the demand for lightweight, flexible, and recyclable materials grows across industries such as automotive, electrical, pagtatayo, and consumer goods, TPEs have become increasingly popular, nagtutulak sa pagbuo ng mga dalubhasang masterbatch at mga teknolohiya ng extrusion na iniayon sa kanilang natatanging mga kinakailangan sa pagproseso.
Masterbatch, bilang isang mahalagang materyal para sa pangkulay at functional modification ng mga TPE, gumaganap ng isang mahalagang papel sa pagpapahusay ng pagganap at pagpapalawak ng saklaw ng aplikasyon ng mga produkto ng TPE. Ang pagproseso ng TPE masterbatch ay nangangailangan ng tumpak na kontrol sa paghahalo, nagkakalat, at mga parameter ng temperatura, dahil ang mga TPE ay may tiyak na lagkit, paglaban sa init, at mga katangian ng pagkalastiko na naiiba sa mga tradisyonal na plastik. Mga twin-screw extruder, sa kanilang higit na mahusay na mga kakayahan sa paghahalo at pagpapakalat, tumpak na kontrol sa temperatura, at kakayahang umangkop sa magkakaibang mga materyales, ay naging pangunahing kagamitan sa pagproseso para sa TPE masterbatch. Zhuoyue, isang propesyonal na tagagawa ng twin-screw extruders, offers a full range of advanced extrusion solutions specifically designed for TPE compounding and masterbatch processing, covering TPE/SBS/TPU/TPR/TPV and other major TPE categories, to meet the diverse needs of manufacturers in different industries.
1. Overview of Thermoplastic Elastomers (TPE): Categories, Properties and Key Characteristics
TPEs are a diverse family of materials, classified into six general commercial categories based on their chemical composition and structure. Each category has unique properties, processing characteristics, and application fields, which directly determine the requirements for masterbatch formulation and extrusion equipment. Understanding the classification and properties of TPEs is the foundation for optimizing masterbatch processing and selecting suitable twin-screw extruders.
1.1 Six General Commercial Categories of TPEs
1.1.1 Styrenic Block Copolymers (TPS, TPE-s).
TPS is the most widely used category of TPEs, accounting for a large share of the global TPE market. It is composed of styrenic blocks (such as polystyrene, PS) and elastomeric blocks (such as polybutadiene, PB; polyisoprene, PI; or ethylene-butylene, EB), connected by covalent bonds. The most common types of TPS include SBS (Styrene-Butadiene-Styrene), SIS (Styrene-Isoprene-Styrene), SEBS (Styrene-Ethylene-Butylene-Styrene), and SEPS (Styrene-Ethylene-Propylene-Styrene).
Key properties of TPS include excellent flexibility, elasticity, and processability. SEBS and SEPS, which are hydrogenated versions of SBS and SIS, have improved heat resistance, weather resistance, and aging resistance, making them suitable for outdoor and high-temperature applications. TPS materials are easily colored and modified with masterbatch, at ang kanilang temperatura sa pagpoproseso ay mula 150 ℃ hanggang 220 ℃, na katugma sa karamihan ng mga twin-screw extruder. Kasama sa mga karaniwang aplikasyon ng TPS ang mga bahagi ng sasakyan, mga wire at cable, mga kalakal ng mamimili, at mga kagamitang medikal.
1.1.2 Thermoplastic Polyolefin Elastomer (TPO, TPE-o).
Ang TPO ay isang pisikal na timpla ng polyolefin (tulad ng polypropylene, PP; o polyethylene, PE) at elastomer (tulad ng ethylene-propylene-diene monomer, EPDM). Pinagsasama nito ang katigasan ng mga polyolefin sa pagkalastiko ng mga elastomer, at may mahusay na paglaban sa kemikal, weather resistance, at mababang temperatura flexibility. Ang mga TPO ay hindi nakakalason, walang amoy, at nare-recycle, ginagawa itong perpekto para sa mga aplikasyon na nangangailangan ng pagiging magiliw sa kapaligiran.
Ang temperatura ng pagproseso ng TPO ay mula 160 ℃ hanggang 230 ℃, at mayroon itong magandang compatibility sa iba't ibang masterbatch (kulay masterbatch, flame-retardant masterbatch, atbp.). TPOs are widely used in automotive exterior parts (such as bumper covers, fender liners), building materials (such as seals, gaskets), and electrical components. Due to their high polyolefin content, TPO masterbatch processing requires extruders with good mixing capabilities to ensure uniform dispersion of pigments and additives.
1.1.3 Thermoplastic Vulcanizates (TPV, TPE-v).
TPV is a dynamically vulcanized blend of polyolefin (usually PP) at elastomer (usually EPDM). During processing, the elastomer phase is vulcanized into small particles and uniformly dispersed in the polyolefin matrix, resulting in excellent elasticity, compression set resistance, and heat resistance. TPVs have better mechanical properties and dimensional stability than traditional TPEs, and can withstand long-term high-temperature exposure (up to 150℃).
TPV processing requires precise temperature control and strong shear force to ensure uniform vulcanization and dispersion. The processing temperature ranges from 170℃ to 240℃, and the material has high viscosity during processing, which places high requirements on the torque and wear resistance of twin-screw extruders. TPVs are widely used in automotive seals, hoses, gaskets, and industrial components that require high performance and durability.
1.1.4 Thermoplastic Polyurethanes (TPU).
TPU is a block copolymer composed of hard segments (diisocyanate and chain extender) and soft segments (polyol). It has excellent elasticity, abrasion resistance, paglaban sa langis, and mechanical strength, and can be adjusted in hardness from very soft (Shore A 30) to very hard (Shore D 85) by changing the ratio of hard and soft segments.
Ang pagproseso ng TPU ay sensitibo sa temperatura at kahalumigmigan. Ang temperatura ng pagproseso ay mula 180 ℃ hanggang 250 ℃, at ang materyal ay dapat na matuyo nang lubusan bago iproseso (nilalaman ng kahalumigmigan ≤0.05%) upang maiwasan ang hydrolysis at pagbuo ng bula. Ang pagpoproseso ng TPU masterbatch ay nangangailangan ng mga extruder na may tumpak na kontrol sa temperatura at mga kakayahan ng vacuum exhaust. Ang TPU ay malawakang ginagamit sa mga wire at cable, mga hose ng sasakyan, sapatos, mga medikal na catheter, at kagamitang pang-sports.
1.1.5 Thermoplastic Copolyesters (TPC, TPE-E).
Ang TPC ay isang block copolymer na binubuo ng polyester hard segment at polyether o polyester soft segments. Ito ay may mahusay na paglaban sa init, paglaban sa kemikal, at mekanikal na katangian, at kayang tiisin ang mataas na temperatura hanggang 150 ℃ sa mahabang panahon. Ang mga TPC ay mayroon ding magandang flexibility at elasticity, ginagawa itong angkop para sa mga application na may mataas na pagganap.
Ang temperatura ng pagproseso ng TPC ay mula 220 ℃ hanggang 280 ℃, na mas mataas kaysa sa iba pang mga kategorya ng TPE. Ito ay may mataas na lagkit sa panahon ng pagproseso at nangangailangan ng mga extruder na may mataas na torque at tumpak na kontrol sa temperatura. Ang pagpoproseso ng masterbatch ng TPC ay nangangailangan din ng espesyal na pansin sa pagpapakalat ng mga pigment at additives upang maiwasang maapektuhan ang mga mekanikal na katangian ng materyal.. Ang mga TPC ay malawakang ginagamit sa mga bahagi ng sasakyan (tulad ng air intake hoses, transmission seal), mga bahagi ng aerospace, at makinarya sa industriya.
1.1.6 Thermoplastic Polyamides (TPA, TPE-A).
Ang TPA ay isang block copolymer na binubuo ng polyamide hard segment at polyether soft segments. Pinagsasama nito ang mataas na lakas, wear resistance, at chemical resistance ng polyamides na may flexibility at elasticity ng polyethers. Ang TPA ay may mahusay na resistensya sa epekto at pagganap ng mababang temperatura, at maaaring gamitin sa malupit na kapaligiran.
Ang temperatura ng pagpoproseso ng TPA ay mula 230 ℃ hanggang 290 ℃, at ito ay may mataas na pagsipsip ng tubig, nangangailangan ng masusing pagpapatuyo bago iproseso. Ang pagpoproseso ng TPA masterbatch ay nangangailangan ng mga extruder na may mataas na wear resistance (dahil sa mataas na tigas ng polyamide) at tumpak na kontrol sa temperatura upang maiwasan ang pagkasira ng materyal. Ang TPA ay malawakang ginagamit sa mga bahagi ng sasakyan (tulad ng mga gears, bearings), mga de-koryenteng konektor, at mga hose sa industriya.
1.2 Mga Pangunahing Katangian ng mga TPE na Nakakaapekto sa Pagproseso ng Masterbatch
Ang mga TPE ay may mga natatanging katangian na nagpapaiba sa kanila sa mga tradisyonal na plastik, at ang mga pag-aari na ito ay direktang nakakaapekto sa pagbabalangkas ng masterbatch at pagpili ng mga kagamitan sa pagpilit. The key properties to consider in masterbatch processing are as follows:
1.2.1 Elasticity and Flexibility.
TPEs have high elasticity and flexibility, which means that the masterbatch must be compatible with the TPE matrix to avoid reducing the material’s elastic performance. The carrier of the masterbatch should have good compatibility with the TPE, and the dispersant should ensure uniform dispersion of pigments without forming agglomerates that could cause stress concentration and reduce flexibility.
1.2.2 Heat Resistance.
Different TPE categories have different heat resistance (processing temperature ranges from 150℃ to 290℃). Masterbatch pigments and additives must have heat resistance matching the TPE processing temperature to avoid decomposition, discoloration, or performance degradation during extrusion. Halimbawa, Ang TPC at TPA ay nangangailangan ng mga pigment na lumalaban sa mataas na temperatura at mga heat stabilizer.
1.2.3 Viscosity at Processability.
Ang mga TPE ay may iba't ibang lagkit sa panahon ng pagproseso (Ang TPV at TPC ay may mas mataas na lagkit, habang ang TPS ay may mas mababang lagkit). Nakakaapekto ito sa puwersa ng paggugupit at mga kinakailangan sa paghahatid ng twin-screw extruder. Ang mga high-viscosity na TPE ay nangangailangan ng mga extruder na may mataas na torque at malakas na kakayahan sa paghahalo, habang ang mga low-viscosity na TPE ay nangangailangan ng tumpak na kontrol sa bilis ng extrusion upang maiwasan ang pag-apaw ng materyal.
1.2.4 Pagsipsip ng kahalumigmigan.
Ilang TPE (tulad ng TPU, TPA) may mataas na pagsipsip ng tubig, na maaaring magdulot ng mga bula, hydrolysis, at iba pang mga depekto sa masterbatch. Ang mga hilaw na materyales (TPE, mga pigment, mga additives) dapat matuyo nang lubusan bago iproseso, at ang extruder ay dapat na nilagyan ng vacuum exhaust device upang alisin ang moisture at volatile substance.
1.2.5 Pagkakatugma sa Additives.
TPEs often require functional additives (such as antioxidants, Mga stabilizer ng UV, mga pampadulas) to improve their performance. The masterbatch should be formulated to ensure that the additives are compatible with both the pigments and the TPE matrix, avoiding chemical reactions that could affect product quality.
2. Masterbatch for TPEs: Composition, Formulation and Processing Requirements
Masterbatch for TPEs is a concentrated mixture of pigments/dyes, mga carrier, and additives, designed to color TPEs and impart additional functions (such as flame retardancy, antistatic, antibacterial) while maintaining the material’s inherent elastic and processing properties. The formulation and processing of TPE masterbatch are more demanding than those for traditional plastics, due to the unique properties of TPEs. This section details the composition, formulation principles, at mga kinakailangan sa pagproseso ng TPE masterbatch.
2.1 Pangunahing Komposisyon ng TPE Masterbatch
Tulad ng tradisyonal na masterbatch, Ang TPE masterbatch ay binubuo ng tatlong pangunahing bahagi: mga pigment/tina, mga carrier, and additives. Ang pagpili at proporsyon ng bawat bahagi ay iniayon sa uri ng TPE at mga kinakailangan sa aplikasyon nito.
2.1.1 Mga Pigment/Tina.
Ang mga pigment/tina ay ang mga pangunahing bahagi na nagbibigay ng kulay sa mga TPE, accounting para sa 10%-70% ng komposisyon ng masterbatch (depende sa intensity ng kulay at uri ng TPE). Ang mga pangunahing kinakailangan para sa mga pigment/tina sa TPE masterbatch ay:
- – Heat Resistance: Dapat makatiis sa temperatura ng pagpoproseso ng target na TPE (150℃-290 ℃) nang walang pagkabulok o pagkawalan ng kulay. Para sa mga TPE na may mataas na temperatura (TPC, TPA), Mas gusto ang mga organikong pigment na lumalaban sa mataas na temperatura o mga inorganic na pigment.
- – Pagkakatugma: Dapat ay tugma sa TPE matrix upang maiwasan ang paglipat, namumulaklak, o nabawasan ang pagkalastiko. Ang mga pigment na may katulad na polarity sa TPE ay mas tugma (hal., polar pigment para sa TPU, mga non-polar na pigment para sa TPS).
- – Dispersibility: Kailangang madaling ikalat sa TPE matrix upang matiyak ang pare-parehong pangkulay at maiwasan ang mga batik ng kulay, mga guhit, o pinababang mekanikal na katangian. Mga pinong-particle na pigment (20-40 mesh) na may mababang agglomeration ay ginustong.
- – Pagkamagiliw sa kapaligiran: Dapat matugunan ang mga pandaigdigang pamantayan sa pangangalaga sa kapaligiran (tulad ng REACH, RoHS) upang maiwasan ang mga nakakalason o nakakapinsalang sangkap (tulad ng mabibigat na metal) na maaaring makaapekto sa kalusugan ng tao at sa kapaligiran.
Kasama sa mga karaniwang pigment na ginagamit sa TPE masterbatch: mga inorganikong pigment (titanium dioxide para sa puti, carbon black para sa black, iron oxide para sa pula/dilaw), at mga organikong pigment na lumalaban sa mataas na temperatura (phthalocyanine asul/berde, quinacridone pula).
2.1.2 Mga carrier.
Ang mga carrier ay ang matrix ng masterbatch, accounting para sa 20%-80% ng komposisyon, and play a key role in dispersing pigments and adhering to the TPE matrix. The carrier must have excellent compatibility with both the pigments and the target TPE, as poor compatibility can lead to pigment migration, uneven coloring, and reduced TPE performance. The selection of the carrier is based on the type of TPE:
- – For TPS (SBS, SEBS): Use TPS or PP as the carrier, which has good compatibility and processing fluidity.
- – For TPO/TPE-o: Use PP or PE as the carrier, matching the polyolefin component of the TPO.
- – For TPV/TPE-v: Use PP as the carrier, which is compatible with the PP matrix of the TPV.
- – For TPU: Use TPU as the carrier, ensuring compatibility with the TPU matrix and avoiding hydrolysis.
- – For TPC/TPE-E and TPA/TPE-A: Use TPC or TPA as the carrier, respectively, to match the high-temperature processing requirements and compatibility.
The carrier should also have good processing fluidity, with a melting point and processing temperature consistent with or slightly lower than the target TPE, to ensure uniform mixing and avoid TPE degradation.
2.1.3 Mga additives.
Additives are auxiliary components added to improve the processing performance, dispersibility, and functional performance of TPE masterbatch, accounting para sa 1%-10% ng komposisyon. The type and dosage of additives are determined by the TPE type and application requirements:
- – Dispersants: The most important additive for TPE masterbatch, used to reduce pigment surface tension, prevent agglomeration, and ensure uniform dispersion in the TPE matrix. Common dispersants include polyethylene wax, polypropylene wax, stearic acid, and maleic anhydride grafted waxes. For high-viscosity TPEs (TPV, TPC), mas gusto ang mga high-efficiency dispersant na may malakas na compatibility.
- – Mga compatibilizer: Ginagamit upang mapabuti ang pagiging tugma sa pagitan ng mga pigment at TPE, at sa pagitan ng masterbatch at TPE matrix. Halimbawa, Ang maleic anhydride grafted PP ay ginagamit bilang isang compatibilizer para sa TPO masterbatch, at polyurethane wax ay ginagamit para sa TPU masterbatch.
- – Mga Heat Stabilizer: Ginagamit upang maiwasan ang pagkabulok ng pigment at pagkasira ng TPE sa panahon ng pagproseso ng mataas na temperatura. Kasama sa mga karaniwang heat stabilizer ang mga organic na stabilizer ng lata (para sa TPU), hadlangan ang phenol antioxidants (para sa TPS, TPO), at phosphite antioxidants (para sa TPC, TPA).
- – Mga UV Stabilizer at Antioxidant: Ginagamit upang mapabuti ang paglaban sa panahon at paglaban sa pagtanda ng mga may kulay na produkto ng TPE, pinipigilan ang pagkupas ng kulay at pagkasira ng pagganap sa ilalim ng sikat ng araw at oxygen. Para sa mga panlabas na aplikasyon (tulad ng mga panlabas na bahagi ng sasakyan), UV absorbers and hindered amine light stabilizers (HALS) are added.
- – Lubricants: Used to reduce friction between materials and extrusion equipment (screw, barrel, die head), improve processing fluidity, and avoid material sticking to equipment. Common lubricants include stearic acid, calcium stearate, and silicone oil. For TPU and TPA, lubricants with low migration are preferred to avoid affecting product performance.
- – Functional Additives: Added to impart special functions to TPEs, such as flame retardants (for wires and cables), antistatic agents (for electrical components), and antibacterial agents (for medical devices and consumer goods).
2.2 Formulation Principles of TPE Masterbatch
The formulation of TPE masterbatch must balance coloring effect, processing performance, and TPE inherent properties. The key principles are as follows:
2.2.1 Compatibility First.
The carrier, mga pigment, and additives must be compatible with the target TPE to avoid reducing the material’s elasticity, kakayahang umangkop, at mekanikal na katangian. Halimbawa, using a non-polar carrier for polar TPU will lead to poor compatibility and pigment migration.
2.2.2 Match Heat Resistance.
The pigments and additives must have heat resistance matching the TPE processing temperature. Halimbawa, TPC masterbatch uses high-temperature resistant pigments (heat resistance ≥280℃) to avoid decomposition during processing.
2.2.3 Optimize Dispersibility.
The pigment content and dispersant dosage are adjusted to ensure uniform dispersion. High-concentration masterbatch (pigment content 50%-70%) requires more dispersants and better mixing capabilities, while low-concentration masterbatch (10%-30%) focuses on compatibility.
2.2.4 Minimize Impact on TPE Properties.
The masterbatch should not significantly affect the TPE’s elasticity, compression set, o paglaban sa hadhad. Halimbawa, ang sobrang dispersant o lubricant ay maaaring mabawasan ang mekanikal na lakas ng TPE.
2.2.5 Pagsunod sa Pangangalaga sa Kapaligiran.
Ang pagbabalangkas ay dapat matugunan ang mga pandaigdigang pamantayan sa pangangalaga sa kapaligiran, pag-iwas sa mga nakakalason o nakakapinsalang sangkap (tulad ng mabibigat na metal, phthalates) na maaaring paghigpitan ang pag-access sa merkado.
2.3 Mga Kinakailangan sa Pagproseso ng TPE Masterbatch
Pangunahing isinasagawa ang pagproseso ng TPE masterbatch gamit ang teknolohiya ng twin-screw extrusion, na nangangailangan ng mahigpit na kontrol ng raw material pretreatment, premixing, mga parameter ng extrusion, at post-processing upang matiyak ang kalidad ng produkto. Ang mga pangunahing kinakailangan sa pagproseso ay ang mga sumusunod:
2.3.1 Pretreatment ng Hilaw na Materyal.
Mga TPE (lalo na ang TPU, TPA) may mataas na pagsipsip ng tubig, kaya lahat ng hilaw na materyales (TPE carrier, mga pigment, mga additives) dapat matuyo nang lubusan bago iproseso. Ang temperatura at oras ng pagpapatayo ay tinutukoy ng uri ng materyal: Ang TPU/TPA ay pinatuyo sa 100-120 ℃ para sa 6-8 oras, Ang TPS/TPO ay pinatuyo sa 80-100 ℃ para sa 3-5 oras, at ang mga pigment ay pinatuyo sa 60-80 ℃ para sa 2-4 oras. Ang moisture content ng mga pinatuyong hilaw na materyales ay dapat kontrolin sa ibaba 0.1% (0.05% para sa TPU/TPA).
Bilang karagdagan, ang mga pigment na may malalaking sukat ng butil o agglomerates ay dapat durugin at salain (20-40 mesh) upang mapabuti ang dispersibility, at mga dumi (mga particle ng metal, alikabok) dapat tanggalin upang maiwasan ang pagkasuot sa extrusion equipment at mga depekto sa masterbatch.
2.3.2 Premixing.
Ang pinatuyong hilaw na materyales (mga pigment, carrier, mga additives) ay halo-halong sa isang high-speed mixer ayon sa formula ratio upang bumuo ng isang pare-parehong paunang timpla. Ang mga parameter ng premixing ay inaayos batay sa uri ng TPE: bilis ng paghahalo 800-1200 rpm, oras ng paghahalo 5-10 minuto, temperatura ng paghahalo 40-60 ℃. Para sa high-concentration masterbatch o high-viscosity TPE carriers, pinahaba ang premixing time, at ang mga dispersant ay idinagdag muna upang mabalot ang mga pigment, pagpapabuti ng dispersibility.
2.3.3 Kontrol ng Mga Parameter ng Extrusion.
Twin-screw extrusion is the core step of TPE masterbatch processing, and the key parameters (temperatura, bilis ng turnilyo, extrusion pressure, feeding speed) must be precisely controlled to match the TPE type:
- – Pagkontrol sa Temperatura: The barrel is divided into 4-6 temperature control sections (feeding section, melting section, mixing section, homogenizing section, die head section). The temperature of each section is adjusted according to the TPE processing temperature. Halimbawa, TPS masterbatch: feeding section 100-120℃, melting section 160-180℃, mixing section 170-190℃, homogenizing section 160-180℃, die head section 150-170℃; TPC masterbatch: feeding section 150-170℃, melting section 230-250℃, mixing section 240-260℃, homogenizing section 230-250℃, die head section 220-240℃. The temperature control precision should reach ±1℃ to avoid TPE degradation and pigment decomposition.
- – Screw Speed: The screw speed ranges from 200-800 rpm, adjusted based on TPE viscosity. High-viscosity TPEs (TPV, TPC) require higher screw speed (500-800 rpm) to generate sufficient shear force for pigment dispersion; low-viscosity TPEs (TPS) use moderate speed (300-500 rpm) to avoid material overflow.
- – Extrusion Pressure: The pressure ranges from 5-12MPa, kept stable (fluctuation ≤±0.5MPa) to ensure uniform mixing and shaping. High-viscosity TPEs require higher pressure, while low-viscosity TPEs use moderate pressure.
- – Feeding Speed: Adjusted to match the screw speed and extrusion speed, ensuring stable and uniform feeding. For high-viscosity TPEs, a forced feeding device is used to avoid material accumulation.
2.3.4 Post-Processing.
After extrusion, the strip-shaped masterbatch is cooled (water tank cooling, 20-30℃), granulated (laki ng butil 2-5mm), na-screen (upang alisin ang mga hindi kwalipikadong particle), at nakabalot (selyadong at moisture-proof na packaging). Para sa moisture-sensitive TPE masterbatch (TPU, TPA), ang tapos na produkto ay tuyo muli bago ang packaging upang maiwasan ang moisture absorption.

4. Mga Full Series Extruder ni Zhuoyue: Mga Propesyonal na Solusyon para sa Pagproseso ng TPE Masterbatch
Matagal nang nakikibahagi si Zhuoyue sa pananaliksik, pag-unlad, at produksyon ng mga high-performance na twin-screw extruder, at nakaipon ng mayamang karanasan sa pagproseso ng masterbatch ng TPE. Batay sa mga natatanging katangian ng pagproseso ng mga TPE (high viscosity, sensitivity ng temperatura, pagsipsip ng kahalumigmigan) at ang magkakaibang pangangailangan ng mga tagagawa (iba't ibang kategorya ng TPE, production scales, application fields), Zhuoyue has launched a full series of extruders suitable for TPE masterbatch processing, including HTS BASIC, HTS PLUS, HTS SUPER, ZTE, and HTE series. Each series has targeted performance advantages, providing personalized and efficient processing solutions for TPE masterbatch manufacturers of different scales.
4.1 Core Advantages of Zhuoyue’s Extruders for TPE Masterbatch Processing
Zhuoyue’s extruders are specially optimized for TPE masterbatch processing, with the following core advantages to meet the strict requirements of TPE processing:
4.1.1 Excellent Mixing and Dispersing Effect.
TPE masterbatch requires uniform dispersion of pigments and additives to avoid affecting the material’s elasticity and mechanical properties. All Zhuoyue’s twin-screw extruders adopt an intermeshing co-rotating structure, with a reasonable screw pitch, lead, and compression ratio design. The intermeshing and rotating of the twin screws generate strong shear force and kneading force, which can fully break pigment agglomerates and ensure uniform dispersion of pigments, mga carrier, and additives in the TPE matrix. The mixing uniformity reaches more than 95%, which is far higher than that of ordinary extruders.
Bilang karagdagan, the screws adopt a modular design, which can freely combine different screw elements (conveying, paghahalo, shearing) according to the TPE type. Halimbawa, high-viscosity TPV/TPC masterbatch requires more mixing and shearing elements to enhance dispersion; low-viscosity TPS masterbatch uses more conveying elements to improve production efficiency.
4.1.2 Precise Temperature Control, Avoiding TPE Degradation.
TPEs are sensitive to temperature, and excessive temperature or temperature fluctuation can lead to material degradation (such as TPU hydrolysis, TPC chain scission). All Zhuoyue’s extruders adopt an advanced intelligent temperature control system, kasama 4-6 independent temperature control sections, temperature control precision of ±1℃, and real-time temperature monitoring and alarm functions. The barrel adopts a double-layer jacket design, realizing rapid heating and cooling, and improving temperature response speed. The die head is equipped with an independent temperature control device, ensuring stable shaping of the masterbatch strip.
4.1.3 High Wear Resistance and Corrosion Resistance.
Some TPE masterbatches (such as TPA, TPC) contain high-hardness pigments or additives, which can wear the screw and barrel. Zhuoyue’s extruders use high-quality wear-resistant materials and advanced manufacturing technologies: HTS PLUS/SUPER/HTE series screws and barrels are made of imported wear-resistant alloy steel, undergoing bimetallic composite or laser cladding treatment, surface hardness ≥65 HRC (HTS SUPER series ≥70 HRC), service life 2-3 times that of ordinary extruders; HTS BASIC/ZTE series screws and barrels are nitrided, surface hardness ≥60 HRC, meeting the needs of ordinary TPE masterbatch processing.
4.1.4 Vacuum Exhaust and Moisture Removal Capabilities.
TPEs such as TPU and TPA have high water absorption, and moisture can cause bubbles and defects in the masterbatch. All Zhuoyue’s mid-to-high-end extruders (HTS PLUS/SUPER/HTE) are equipped with a vacuum exhaust device, which can effectively remove moisture, pabagu-bago ng isip na mga sangkap, at hangin sa materyal, tinitiyak ang density at kalidad ng masterbatch. Ang vacuum degree ay adjustable (0.06-0.09MPa), pag-angkop sa iba't ibang mga kinakailangan sa nilalaman ng kahalumigmigan.
4.1.5 Mataas na Production Efficiency at Energy Saving.
Ang mga extruder ni Zhuoyue ay gumagamit ng mga high-torque na gearbox at mga na-optimize na istruktura ng screw, na may malakas na kapasidad sa paghahatid at mataas na kahusayan sa produksyon. Kung ikukumpara sa mga ordinaryong extruder, ang kahusayan sa produksyon ay nadaragdagan ng 20%-50%, at ang pagkonsumo ng enerhiya ay nababawasan ng 15%-25%. Halimbawa, Ang kapasidad ng produksyon ng serye ng HTS SUPER ay umabot sa 1000-3000kg/h, angkop para sa malakihang produksyon ng masa; Ang kapasidad ng produksyon ng serye ng ZTE ay 50-400kg/h, suitable for small-batch production.
4.1.6 Intelligent Control at Madaling Operasyon.
Ang lahat ng mga extruder ay gumagamit ng isang PLC intelligent control system at touch screen operation interface, na maaaring mag-imbak ng hanggang sa 100 set ng formula at mga parameter ng pagproseso. When switching between different TPE masterbatches, only the corresponding parameters need to be called, avoiding repeated debugging. The HTS SUPER series is equipped with cloud control functions, realizing remote parameter adjustment, production data monitoring, at predictive na pagpapanatili, realizing intelligent production management.
4.1.7 Wide Adaptability.
Zhuoyue’s full series of extruders can adapt to the processing of all TPE categories (TPS/SBS/TPU/TPR/TPV/TPC/TPA) and masterbatch types (kulay masterbatch, flame-retardant masterbatch, antistatic masterbatch), with pigment content ranging from 10% sa 70%.
