2.2.3 Dispersibility अनुकूलन गर्नुहोस्.
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. उदाहरणका लागि, 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 (जस्तै भारी धातुहरू, 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) उच्च पानी अवशोषण छ, so all raw materials (TPE carrier, पिगमेन्ट, additives) प्रशोधन गर्नु अघि राम्ररी सुक्नु पर्छ. The drying temperature and time are determined by the material type: TPU/TPA is dried at 100-120℃ for 6-8 घण्टा, TPS/TPO is dried at 80-100℃ for 3-5 घण्टा, and pigments are dried at 60-80℃ for 2-4 घण्टा. The moisture content of dried raw materials should be controlled below 0.1% (0.05% for TPU/TPA).
साथै, pigments with large particle sizes or agglomerates should be crushed and sieved (20-40 जाल) to improve dispersibility, and impurities (metal particles, धुलो) should be removed to avoid wear on extrusion equipment and defects in masterbatch.
2.3.2 प्रिमिक्स गर्दै.
The dried raw materials (पिगमेन्ट, carrier, additives) 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 आरपीएम, मिश्रण समय 5-10 मिनेट, 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 (तापमान, पेंच गति, extrusion pressure, feeding speed) must be precisely controlled to match the TPE type:
- – तापक्रम नियन्त्रण: The barrel is divided into 4-6 तापमान नियन्त्रण खण्डहरू (खुवाउने खण्ड, पग्लने खण्ड, mixing section, homogenizing section, die head section). The temperature of each section is adjusted according to the TPE processing temperature. उदाहरणका लागि, 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.
- – स्क्रू गति: The screw speed ranges from 200-800 आरपीएम, adjusted based on TPE viscosity. High-viscosity TPEs (VAT, TPC) require higher screw speed (500-800 आरपीएम) to generate sufficient shear force for pigment dispersion; low-viscosity TPEs (TPS) use moderate speed (300-500 आरपीएम) to avoid material overflow.
- – एक्सट्रुजन दबाव: 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. उच्च चिपचिपा TPEs को लागी, 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.

4.1 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, वाहकहरू, and additives in the TPE matrix. The mixing uniformity reaches more than 95%, which is far higher than that of ordinary extruders.
साथै, the screws adopt a modular design, which can freely combine different screw elements (सम्प्रेषण गर्दै, मिश्रण, काटन) according to the TPE type. उदाहरणका लागि, 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, संग 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.

4.1.4 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%. उदाहरणका लागि, 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.
