TPE ta un famia diverso di material, klasifiká den seis kategoria komersial general a base di nan komposishon i struktura kímiko. Kada kategoria tin propiedatnan úniko, karakterístika di prosesamentu, i terenonan di aplikashon, ku ta determiná direktamente e rekisitonan pa formulashon di masterbatch i ekipo di ekstrushon. Komprondementu di e klasifikashon i propiedatnan di TPE ta e fundeshi pa optimalisá prosesamentu di masterbatch i selekshon di ekstrudernan di dos skru adekuá.
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, and their processing temperature ranges from 150℃ to 220℃, which is compatible with most twin-screw extruders. Common applications of TPS include automotive components, wires and cables, consumer goods, and medical devices.
1.1.2 Thermoplastic Polyolefin Elastomers (TPO, TPE-o).
TPO is a physical blend of polyolefin (such as polypropylene, PP; or polyethylene, PE) and elastomer (such as ethylene-propylene-diene monomer, EPDM). It combines the rigidity of polyolefins with the elasticity of elastomers, and has excellent chemical resistance, weather resistance, and low temperature flexibility. TPOs are non-toxic, odorless, and recyclable, making them ideal for applications requiring environmental friendliness.
The processing temperature of TPO ranges from 160℃ to 230℃, and it has good compatibility with various masterbatches (color masterbatch, flame-retardant masterbatch, etc.). 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) and 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, i resistensia na kalor. TPVs have better mechanical properties and dimensional stability than traditional TPEs, and can withstand long-term high-temperature exposure (up to 150℃).
Prosesamentu di TPV ta rekerí kontrol di temperatura presis i forsa di kòrtamentu fuerte pa garantisá vulkanisashon i dispershon uniforme. E temperatura di prosesamentu ta varia di 170°C pa 240°C, i e material tin viskosidat haltu durante prosesamentu, ku ta pone eksigensianan haltu riba e resistensia di torsi i desgaste di e ekstrusornan di dos skru. TPV ta wòrdu usá ampliamente den seyo di outo, slangnan, gaskets, i komponentenan industrial ku ta rekerí rendimentu i durabilidat haltu.
1.1.4 Poliuretanonan Termoplástiko (TPU).
TPU ta un kopolimero di blòki komponé di segmentonan duru (diisocianato i ekstensor di kadena) i segmentonan suave (poliol). E tin un elastisidat ekselente, resistensia na abrashon, resistensia di zeta, i forsa mekaniko, i por wòrdu ahusta den duru for di hopi suave (Kosta A 30) pa hopi duru (Kosta D 85) dor di kambia e relashon di segmentonan duru i suave.
TPU processing is sensitive to temperature and moisture. The processing temperature ranges from 180℃ to 250℃, and the material must be thoroughly dried before processing (moisture content ≤0.05%) to avoid hydrolysis and bubble formation. TPU masterbatch processing requires extruders with precise temperature control and vacuum exhaust capabilities. TPU is widely used in wires and cables, automotive hoses, footwear, medical catheters, and sports equipment.
1.1.5 Thermoplastic Copolyesters (TPC, TPE-E).
TPC is a block copolymer composed of polyester hard segments and polyether or polyester soft segments. It has excellent heat resistance, chemical resistance, and mechanical properties, and can withstand high temperatures up to 150℃ for long periods. TPCs also have good flexibility and elasticity, making them suitable for high-performance applications.
The processing temperature of TPC ranges from 220℃ to 280℃, which is higher than other TPE categories. It has high viscosity during processing and requires extruders with high torque and precise temperature control. TPC masterbatch processing also requires special attention to the dispersion of pigments and additives to avoid affecting the material’s mechanical properties. TPCs are widely used in automotive components (such as air intake hoses, transmission seals), aerospace parts, and industrial machinery.
1.1.6 Thermoplastic Polyamides (TPA, TPE-A).
TPA is a block copolymer composed of polyamide hard segments and polyether soft segments. It combines the high strength, resistensia na desgaste, and chemical resistance of polyamides with the flexibility and elasticity of polyethers. TPA tin un resistensia di impakto ekselente i un rendimentu di temperatura abou, i por wòrdu usá den ambientenan duru.
E temperatura di prosesamentu di TPA ta varia di 230°C pa 290°C, i e tin absorshon haltu di awa, ku ta rekerí sekumentu profundo promé ku prosesá. Prosesamentu di masterbatch di TPA ta rekerí ekstrudónan ku resistensia haltu na desgaste (debí na e duru haltu di poliamida) i kòntròl di temperatura presis pa evitá degradashon di material. TPA ta wòrdu usá ampliamente den komponentenan di outo (manera engranahenan, bearingnan), konektornan eléktriko, i slangnan industrial.
1.2 Propiedatnan Klave di TPEs ku ta Afektá Prosesamentu di Masterbatch
TPE tin propiedatnan úniko ku ta distinguí nan for di plèstik tradishonal, i e propiedatnan aki ta afektá direktamente e formulashon di masterbatch i e selekshon di ekipo di ekstrushon. 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. Por ehèmpel, TPC and TPA require high-temperature resistant pigments and heat stabilizers.
1.2.3 Viscosity and Processability.
TPEs have varying viscosities during processing (TPV and TPC have higher viscosity, while TPS has lower viscosity). This affects the shear force and conveying requirements of the twin-screw extruder. High-viscosity TPEs require extruders with high torque and strong mixing capabilities, while low-viscosity TPEs require precise control of extrusion speed to avoid material overflow.
1.2.4 Moisture Absorption.
Some TPEs (such as TPU, TPA) have high water absorption, which can cause bubbles, hydrolysis, and other defects in the masterbatch. The raw materials (TPE, pigments, additives) must be thoroughly dried before processing, and the extruder should be equipped with a vacuum exhaust device to remove moisture and volatile substances.
1.2.5 Compatibility with Additives.
TPEs hopi bia ta rekerí aditivonan funshonal (manera antioksidantenan, Stabilisadónan UV, lubrikantenan) pa mehorá nan rendimentu.

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 Additives.
Additives are auxiliary components added to improve the processing performance, dispersibility, and functional performance of TPE masterbatch, kontabilidat pa 1%-10% di e komposishon. 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), dispersante di efisiensia haltu ku kompatibilidat fuerte ta wòrdu preferá.
- – Kompatibilisadónan: Usá pa mehorá kompatibilidat entre pigmentonan i TPEs, i entre masterbatch i matris di TPE. Por ehèmpel, PP injertá di anhidrido maleiko ta wòrdu usá komo un kompatibilisadó pa e masterbatch di TPO, i sera di poliuretano ta wòrdu usá pa e masterbatch di TPU.

2.2.5 Environmental Protection Compliance.
The formulation must meet global environmental protection standards, avoiding toxic or harmful substances (manera metalnan pisá, phthalates) that could restrict market access.
2.3 Processing Requirements of TPE Masterbatch
TPE masterbatch processing is mainly carried out using twin-screw extrusion technology, which requires strict control of raw material pretreatment, premixing, extrusion parameters, and post-processing to ensure product quality. The key processing requirements are as follows:
2.3.1 Raw Material Pretreatment.
TPEs (especially TPU, TPA) have high water absorption, so all raw materials (TPE carrier, pigments, additives) must be thoroughly dried before processing. The drying temperature and time are determined by the material type: TPU/TPA is dried at 100-120℃ for 6-8 oranan, TPS/TPO is dried at 80-100℃ for 3-5 oranan, i pigmentonan ta wòrdu seku na 60-80°C pa 2-4 oranan. E kontenido di humedat di materia prima seku mester ta kontrolá bou di 0.1% (0.05% pa TPU/TPA).
Ademas, pigmentonan ku tamaño di partikulo grandi òf aglomeradonan mester wòrdu triturá i tamia (20-40 mesh) pa mehorá dispersibilidat, i impuresanan (partikulonan di metal, stòf) mester wòrdu kita pa evitá desgaste riba ekipo di ekstrushon i defektonan den masterbatch.
2.3.2 Pre-meskla.
E materia prima seku (pigments, transportador, additives) ta wòrdu mesklá den un meskla di velosidat haltu segun e proporshon di fórmula pa forma un meskla preliminar uniforme. E parameternan di premezkla ta wòrdu ahusta a base di e tipo di TPE: velosidat di meskla 800-1200 rpm, tempu di meskla 5-10 minütnan, temperatura di meskla 40-60°C. Pa portadónan di TPE di masterbatch di konsentrashon haltu òf di viskosidat haltu, e tempu di premeskla ta wòrdu prolongá, i dispersantenan ta wòrdu agregá promé pa tapa e pigmentonan, mehorashon di dispersibilidat.
2.3.3 Kontrol di Parameternan di Ekstrushon.
Ekstrushon di dos skru ta e paso sentral di prosesamentu di masterbatch di TPE, i e parameternan klave (temperatura, velosidat di skru, preshon di ekstrushon, velosidat di alimentashon) mester ta kontrolá presis pa kuadra ku e tipo di TPE:
- – Kontrol di Temperatura: E bari ta dividí den 4-6 sekshonnan di kòntròl di temperatura (sekshon di alimentashon, sekshon di smelt, sekshon di meskla, sekshon di homogenisashon, sekshon di kabes di muri). E temperatura di kada sekshon ta wòrdu ahusta segun e temperatura di prosesamentu di TPE. Por ehèmpel, TPS masterbatch: sekshon di alimentashon 100-120°C, sekshon di smelt 160-180°C, sekshon di meskla 170-190°C, sekshon di homogenisashon 160-180°C, sekshon di kabes di muri 150-170°C; TPC masterbatch: sekshon di alimentashon 150-170°C, sekshon di smelt 230-250°C, sekshon di meskla 240-260°C, sekshon di homogeneisashon 230-250°C, sekshon di kabes di muri 220-240°C. 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 (particle size 2-5mm), screened (to remove unqualified particles), and packaged (sealed and moisture-proof packaging). For moisture-sensitive TPE masterbatch (TPU, TPA), the finished product is dried again before packaging to prevent moisture absorption.

4. Zhuoyue’s Full Series Extruders: Professional Solutions for TPE Masterbatch Processing
Zhuoyue has long been engaged in the research, development, and production of high-performance twin-screw extruders, and has accumulated rich experience in TPE masterbatch processing. Based on the unique processing characteristics of TPEs (viskosidat haltu, temperature sensitivity, moisture absorption) and the diverse needs of manufacturers (different TPE categories, 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, transportadónan, and additives in the TPE matrix. The mixing uniformity reaches more than 95%, which is far higher than that of ordinary extruders.
Ademas, the screws adopt a modular design, which can freely combine different screw elements (conveying, meskla, kòrtamentu) according to the TPE type. Por ehèmpel, 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, with 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. E ekstrudernan di Zhuoyue ta usa materialnan di kalidat haltu ku ta resistí desgaste i teknologianan di fabrikashon avansá: E skru i bari di serie HTS PLUS/SUPER/HTE ta trahá di staal di aleashon importá ku ta resistí desgaste, pasando den tratamentu di komposito bimetáliko òf revestimentu di laser, duru di superfisie ≥65 HRC (HTS SUPER series ≥70 HRC), bida di servisio 2-3 biaha esun di ekstrudernan komun; E seri HTS BASIC/ZTE ta skru i bari ta nitridá, duresa di superfisie ≥60 HRC, kumpli ku e nesesidatnan di prosesamentu di masterbatch di TPE komun.
