PFA is the copolymer of TFE and PPVE, with excellent chemical stability, electrical insulating property, age resistance and low friction. Its high temperature mechanical property is much higher than PTFE, and it can be processed as common thermoplastics with extrusion, blow molding, injection molding and other general thermoplastic processing technology Conformable with: Q/0321DYS 017
