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.

TPU has good processing properties such as injection, extrusion, calendering, blow molding, and molding. It is used in the three major shoemaking projects of soles, uppers, and fitting, and is favored by the majority of shoemakers. As can be seen from the picture below, TPU covers almost the entire range of shoe manufacturing processes.

In order to reduce the cost of products and obtain additional properties, polyurethane thermoplastic elastomer can be used as a common toughening agent to toughen many kinds of thermoplastic plastics and modified rubber materials.

As an excellent elastomer, the downstream product of TPU is very broad, and it is widely used in the fields of daily necessities, sporting goods, toys, decorative materials, and so on.
