Vulcanization Thermoplastic Elastomers (TPE) from China Suppliers & Factory: EPDM and Silicone Rubber Solutions
Product Introduction
Dynamic Vulcanized TPE Material is engineered using EPDM rubber or silicone rubber as base materials, processed via twin-screw extrusion with dynamic vulcanization. The technology merges the intrinsic properties of base rubber with thermoplastic plasticity, enabling efficient molding while retaining elastic performance. Boasting exceptional stability, it resists oxidation, UV radiation, hydrolysis, and chemical corrosion. EPDM-based TPV excels in outdoor environments, ideal for door/window and automotive seals. Silicone-based TPV, meanwhile, suits human-wear scenarios, applied in gas mask seals, PC-coated swimming goggles, and electronic wearables. Its versatility bridges industrial durability and biocompatibility, making it a reliable choice for diverse sealing and wearable applications.
