ETFE Granules provide excellent chemical resistance, high thermal stability, and superior mechanical durability. Designed for industrial coatings, wire insulation, and specialized applications, they ensure long-term performance, reliable processing, and environmental stability.
Product Overview
ETFE granules are a high-performance thermoplastic made from ethylene-tetrafluoroethylene copolymer (ETFE), known for its outstanding mechanical properties, weather resistance, flame retardancy, gas barrier properties, and chemical resistance. ETFE also features excellent radiation resistance, strong metal surface adhesion, and a lighter weight compared to other fluoropolymers. These granules can be processed using techniques such as spraying, rolling, extrusion, and injection molding, making them suitable for a wide range of applications, including corrosion-resistant linings, films, hoses, cables, and more, in industries such as chemical, agriculture, construction, electronics, and automotive.
