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, molding suntik, blow molding, jsb.) 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, fléksibel, and recyclable materials grows across industries such as automotive, electrical, pangwangunan, jeung barang konsumén, TPEs have become increasingly popular, driving the development of specialized masterbatch and extrusion technologies tailored to their unique processing requirements.
Masterbatch, as a key material for coloring and functional modification of TPEs, plays a crucial role in enhancing the performance and expanding the application scope of TPE products. The processing of TPE masterbatch requires precise control of mixing, dispersing, and temperature parameters, as TPEs have specific viscosity, lalawanan panas, and elasticity characteristics that differ from traditional plastics. Extruders kembar-screw, with their superior mixing and dispersing capabilities, precise temperature control, and adaptability to diverse materials, have become the core processing equipment for TPE masterbatch.

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, selang, 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, oil resistance, 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.
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, lalawanan kimiawi, 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, ngagem lalawanan, and chemical resistance of polyamides with the flexibility and elasticity of polyethers. TPA has excellent impact resistance and low temperature performance, and can be used in harsh environments.
The processing temperature of TPA ranges from 230℃ to 290℃, and it has high water absorption, requiring thorough drying before processing. TPA masterbatch processing requires extruders with high wear resistance (due to the high hardness of polyamide) and precise temperature control to avoid material degradation. TPA is widely used in automotive components (such as gears, bantalan), electrical connectors, and industrial hoses.
1.2 Key Properties of TPEs Affecting Masterbatch Processing
TPEs have unique properties that distinguish them from traditional plastics, and these properties directly affect the formulation of masterbatch and the selection of extrusion equipment. 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. Salaku conto, TPC sareng TPA ngabutuhkeun pigmén tahan suhu luhur sareng penstabil panas.

2.1 Core Composition of TPE Masterbatch
Like traditional masterbatch, TPE masterbatch consists of three basic components: pigments/dyes, pamawa, jeung aditif. The selection and proportion of each component are tailored to the type of TPE and its application requirements.
2.1.1 Pigments/Dyes.
Pigments/dyes are the core components that impart color to TPEs, accounting for 10%-70% of the masterbatch composition (depending on the color intensity and TPE type). The key requirements for pigments/dyes in TPE masterbatch are:
- – Heat Resistance: Must withstand the processing temperature of the target TPE (150℃-290℃) without decomposition or discoloration. For high-temperature TPEs (TPC, TPA), high-temperature resistant organic pigments or inorganic pigments are preferred.
- – Compatibility: Must be compatible with the TPE matrix to avoid migration, blooming, or reduced elasticity. Pigments with similar polarity to the TPE are more compatible (misalna., polar pigments for TPU, non-polar pigments for TPS).
- – Dispersibility: Must be easily dispersed in the TPE matrix to ensure uniform coloring and avoid color spots, streaks, or reduced mechanical properties. Fine-particle pigments (20-40 bolong) with low agglomeration are preferred.
- – Environmental Friendliness: Must meet global environmental protection standards (such as REACH, RoHS) to avoid toxic or harmful substances (such as heavy metals) that could affect human health and the environment.
Common pigments used in TPE masterbatch include: inorganic pigments (titanium dioxide for white, carbon black for black, iron oxide for red/yellow), and high-temperature resistant organic pigments (phthalocyanine blue/green, quinacridone red).
2.1.2 Carriers.
Carriers are the matrix of the masterbatch, accounting for 20%-80% of the composition, 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, pikeun nyocogkeun sarat processing suhu luhur sarta kasaluyuan.

Dispersants umum kaasup lilin poliétilén, lilin polipropilén, asam stearic, jeung maleat anhidrida grafted lilin. Pikeun TPEs viskositas tinggi (PPN, TPC), high-efficiency dispersants with strong compatibility are preferred.
- – Compatibilizers: Used to improve compatibility between pigments and TPEs, and between masterbatch and TPE matrix. Salaku conto, maleic anhydride grafted PP is used as a compatibilizer for TPO masterbatch, and polyurethane wax is used for TPU masterbatch.
- – Heat Stabilizers: Used to prevent pigment decomposition and TPE degradation during high-temperature processing. Common heat stabilizers include organic tin stabilizers (for TPU), hindered phenol antioxidants (for TPS, TPO), and phosphite antioxidants (for TPC, TPA).
- – UV Stabilizers and Antioxidants: Used to improve the weather resistance and aging resistance of colored TPE products, preventing color fading and performance degradation under sunlight and oxygen. For outdoor applications (such as automotive exterior parts), Penyerap UV sareng penstabil cahaya amina anu ngahalangan (HALS) anu ditambahkeun.

The formulation must meet global environmental protection standards, avoiding toxic or harmful substances (such as heavy metals, 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) gaduh nyerep cai anu luhur, so all raw materials (TPE carrier, pigmén, aditif) kudu tuntas garing saméméh ngolah. The drying temperature and time are determined by the material type: TPU/TPA is dried at 100-120℃ for 6-8 jam, TPS/TPO is dried at 80-100℃ for 3-5 jam, sarta pigmén anu garing dina 60-80 ℃ pikeun 2-4 jam. Eusi Uap bahan baku garing kudu dikawasa handap 0.1% (0.05% pikeun TPU / TPA).

2.3.2 Premixing.
Bahan baku garing (pigmén, pamawa, aditif) dicampur dina mixer-speed tinggi nurutkeun rasio rumus pikeun ngabentuk campuran awal seragam. Parameter premixing disaluyukeun dumasar kana tipe TPE: speed nyampur 800-1200 rpm, waktos nyampur 5-10 menit, hawa campur 40-60 ℃. Pikeun masterbatch konsentrasi luhur atanapi operator TPE viskositas tinggi, waktos premixing diperpanjang, sarta dispersants ditambahkeun munggaran pikeun coating pigmén, ngaronjatkeun dispersibility.
2.3.3 Parameter ékstrusi Control.
Twin-screw extrusion is the core step of TPE masterbatch processing, and the key parameters (temperature, speed screw, extrusion pressure, feeding speed) must be precisely controlled to match the TPE type:
- – Temperature Control: The barrel is divided into 4-6 temperature control sections (feeding section, melting section, mixing section, homogenizing section, bagian sirah maot). The temperature of each section is adjusted according to the TPE processing temperature. Salaku conto, 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 (PPN, 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. Pikeun TPEs viskositas tinggi, 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.
3. Application Fields of TPE Masterbatch and Matching Zhuoyue Extruder Solutions
