PFA Granule
Introduction of 【PFA】 PFA plastic is a copolymer of a small amount of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene. The melt cohesiveness is enhanced, the solution viscosity is reduced, and the performance is unchanged compared with PTFE. This kind of resin can be directly processed into products by ordinary thermoplastic molding methods. Suitable for the production of corrosion-resistant parts, anti-wear parts, seals, insulation and medical equipment parts, high-temperature wires, cable insulation, anti-corrosion equipment, sealing materials, pump valve bushings, and chemical containers.<br />Characteristics of PFA] 1. Crystalline material, moisture absorption is small. It can be processed into products by common thermoplastic processing methods. 2. Suitable for the production of corrosion-resistant parts, anti-wear parts, seals, insulation parts and medical equipment parts. 3. High temperature wire, cable insulation layer, anti-corrosion equipment, sealing material, pump valve bushing, and chemical container.
