Description
PFA PARTICLE
Perfluoro-n-Propyl Vinyl Ether-Tetrafluoroethylene Copolymer, Referred To As PFA, Is Commonly Known As Fusible Polytetrafluoroethylene. It Has Excellent Chemical Stability, Physical And Mechanical Properties, Electrical Insulation And High-Frequency Characteristics, Non-Stickiness, Aging Resistance, Weather Resistance, Flame Retardancy And Thermal Stability. In Addition, Its Mechanical Properties At High Temperatures The Performance Is About 2 Times That Of Ordinary PTFE, And Is Even Considered To Have Superior Performance Than FEP. PFA Products Are Divided Into Three Forms: Powder, Liquid And Granule. They Can Be Processed Through Spraying, Roller Coating, Extrusion, Injection Molding, Transfer And Compression Molding And Other Technologies. Mirrors, Containment Tubes, Pump Parts, Anti-Corrosion Linings), Films, Cable Sheaths, Non-Stick Coatings, Semiconductor Injection Molded Parts And Other Product Forms, Which Are Widely Used In Chemical Industry, Machinery, Electrical, Aerospace, Medical, Food And Semiconductor, Etc. Field.
