PFA film
PFA film: It is a new type of crystalline perfluorocarbon polymer and a modified product of polytetrafluoroethylene. Its long-term use temperature is -80∽260℃, and it has excellent chemical stability and outstanding surface. Non-stickiness, low temperature mechanical strength, electrical insulation, air tightness, crease resistance, and very low water absorption and friction coefficient, and the exposure life in the atmosphere can exceed 20 years.
Polyperfluoroethylene propylene sheet and film are made of polyperfluoroethylene propylene resin by extrusion or blow molding. They are mainly used for anti-corrosion, anti-sticking, air-permeable and light-transmitting parts, insulation of electronic appliances, and composite boards. Mezzanine and so on.
