1.2.1 Elasticity a me ka hikiwawe.
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, ka waihoʻoluʻu, or performance degradation during extrusion. ʻo kahi laʻana, TPC and TPA require high-temperature resistant pigments and heat stabilizers.

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.

Masterbatch for TPEs is a concentrated mixture of pigments/dyes, nā mea lawe, a me nā mea hoʻohui, designed to color TPEs and impart additional functions (e like me ka lapalapa ahi, antistatic, mea kūʻokoʻa) 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.

Hoʻohana ʻia nā puaʻa maʻamau ma TPE masterbatch: nā puaʻa ʻole (titanium dioxide no keokeo, kalapona ʻeleʻele no ka ʻeleʻele, iron oxide no ka ʻulaʻula/melemele), a me nā ʻano puaʻa kūlohelohe kiʻekiʻe (phthalocyanine uliuli/'ōmaʻomaʻo, ʻulaʻula quinacridone).
2.1.2 Nā mea lawe.
ʻO nā mea lawe ka matrix o ka masterbatch, helu helu no 20%-80% o ka haku mele ana, a hoʻokani i kahi hana nui i ka hoʻopuehu ʻana i nā puaʻa a me ka pili ʻana i ka matrix TPE. Pono ka mea lawe i ka hoʻohālikelike maikaʻi me nā puaʻa a me ka TPE i manaʻo ʻia, no ka mea, hiki i ka hoʻohālikelike maikaʻi ʻole ke alakaʻi i ka neʻe ʻana o ka pigment, kala like ʻole, a hoemi i ka hana TPE. ʻO ke kohoʻana o ka mea lawe ma muli o keʻano o TPE:

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, or abrasion resistance. ʻo kahi laʻana, excessive dispersants or lubricants may reduce the TPE’s mechanical strength.

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, hooulu ana, 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 (high viscosity, 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, nā mea lawe, and additives in the TPE matrix. The mixing uniformity reaches more than 95%, which is far higher than that of ordinary extruders.
Kahi mea hou aʻe, the screws adopt a modular design, hiki ke hoʻohui like ʻole i nā mea ʻokoʻa wili (lawe ana, huikau, ʻako ʻako) according to the TPE type. ʻo kahi laʻana, 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, me 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, volatile substances, and air in the material, ensuring the density and quality of the masterbatch. The vacuum degree is adjustable (0.06-0.09MPa), adapting to different moisture content requirements.
4.1.5 High Production Efficiency and Energy Saving.
Zhuoyue’s extruders adopt high-torque gearboxes and optimized screw structures, with strong conveying capacity and high production efficiency. Compared with ordinary extruders, production efficiency is increased by 20%-50%, and energy consumption is reduced by 15%-25%. ʻo kahi laʻana, HTS SUPER series production capacity reaches 1000-3000kg/h, suitable for large-scale mass production; ZTE series production capacity is 50-400kg/h, suitable for small-batch production.
4.1.6 Intelligent Control and Easy Operation.
All extruders adopt a PLC intelligent control system and touch screen operation interface, which can store up to 100 sets of formula and processing parameters. When switching between different TPE masterbatches, ʻo nā ʻāpana pili wale nō e pono ke kāhea ʻia, ka pale ʻana i ka hoʻopio hou ʻana.
