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, pigmentos, and additives must be compatible with the target TPE to avoid reducing the material’s elasticity, flexibilidad, yéetel propiedades mecánicas. jéel bix, 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. jéel bix, 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, or abrasion resistance. jéel bix, excessive dispersants or lubricants may reduce the TPE’s mechanical strength.
2.2.5 Environmental Protection Compliance.
The formulation must meet global environmental protection standards, avoiding toxic or harmful substances (bey metales aalo'ob, 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) yaan ka'anal absorción ja', so all raw materials (TPE carrier, pigmentos, aditivos) k'a'abéet u jach tikintal bey ma' u meyajta'al. The drying temperature and time are determined by the material type: TPU/TPA is dried at 100-120℃ for 6-8 oora'ob, TPS/TPO is dried at 80-100℃ for 3-5 oora'ob, and pigments are dried at 60-80℃ for 2-4 oora'ob. The moisture content of dried raw materials should be controlled below 0.1% (0.05% for TPU/TPA).
Beyxan, pigments with large particle sizes or agglomerates should be crushed and sieved (20-40 malla) to improve dispersibility, and impurities (metal particles, polbóo) should be removed to avoid wear on extrusion equipment and defects in masterbatch.
2.3.2 Premixing.
The dried raw materials (pigmentos, carrier, aditivos) are mixed in a high-speed mixer according to the formula ratio to form a uniform preliminary mixture. The premixing parameters are adjusted based on the TPE type: mixing speed 800-1200 rpm, mixing time 5-10 minuto'ob, mixing temperature 40-60℃. For high-concentration masterbatch or high-viscosity TPE carriers, the premixing time is extended, and dispersants are added first to coat the pigments, improving dispersibility.
2.3.3 Extrusion Parameters Control.
Twin-screw extrusion is the core step of TPE masterbatch processing, and the key parameters (téemperatura, velocidad le tornillo, presión u extrusión, feeding speed) must be precisely controlled to match the TPE type:
- – Kaambalil yo'osal u temperatura: The barrel is divided into 4-6 temperature control sections (jaatsil u tséenta'al, melting section, mixing section, homogenizing section, die head section). The temperature of each section is adjusted according to the TPE processing temperature. jéel bix, 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.
- – Velocidad le tornillo: The screw speed ranges from 200-800 rpm, adjusted based on TPE viscosity. High-viscosity TPEs (IVA, 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.
- – Presión u extrusión: 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°C), 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 (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, portadores, and additives in the TPE matrix. The mixing uniformity reaches more than 95%, which is far higher than that of ordinary extruders.
Beyxan, the screws adopt a modular design, which can freely combine different screw elements (ku ts'aik k'ajóoltbil, xa'ak'tik, corte) according to the TPE type. jéel bix, 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 Kaambalil yo'osal u temperatura preciso, 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, yéetel 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.

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%. jéel bix, 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.
