This article compares extrusion and pelletizing equipment used for TPE, TPR, TPU, TPV, and silicone rubber materials. While all elastomer pelletizing lines share core components—such as twin-screw or single-screw extruders, cooling systems, and pelletizers—each material has specific equipment needs. TPU requires precise temperature and moisture control, TPV demands high-torque twin-screw extruders for dynamic vulcanization, and silicone uses specialized extruders with vacuum degassing and curing systems. Overall, process optimization and tailored screw configurations are key to achieving high-quality pellets and efficient production.

Discover the essential equipment for TPE pelletizing, including extruders, pelletizers, and mixers, plus supporting systems like cooling and drying units. Learn how production scale influences equipment choice—from single screw extruders for small batches to twin screw extrusion lines with underwater pelletizers for large-scale, high-quality TPE granule production.

This article shares practical methods to improve and control the melt flow rate (MFR) of TPE (thermoplastic elastomers) during pelletizing and injection molding. Key strategies include adjusting the oil content in SEBS/SBS base resins, optimizing formulations by selecting higher MFI PP/PS and adjusting fillers and lubricants, and fine-tuning processing conditions such as temperature, screw shear rate, injection speed, and holding time. Together, these approaches help achieve better flowability, stable processing, and high-quality TPE products.
