PFA(perfluoroalkoxy) plastic is a flexible fluoropolymer, which has very excellent che mical propertis, such as,
1. Corrosion resistant to all chemicals
2. Lowest coefficient of friction among plastics
3. Excellent creep resistance and compressive strength
4. High tensile strength and good dielectric properties
5. Excellent radiation resistance
6. Service temperature is -80-260 ℃
PFA material main application fields:
1. Corrosion resistant parts, seals, insulating parts and medical device parts
2. Anti-corrosion equipment, pump and valve bushings
3. Chemical containers
