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.
PFA is a new type of crystalline perfluorocarbon polymer, which is a modified product of polytetrafluoroethylene.
1. name PFA film, Teflon film, Teflon film, transparent Teflon film
2. color transparent; other colors can be customized
3. features
1. High temperature resistance: long-term use temperature is -80 ∽ 260 ℃;
2. Corrosion resistance: corrosion resistance to all chemicals; Can withstand all strong acids, strong oxidants, strong reducing agents and various organic solvents except molten alkali metals, fluorinated media and those higher than 300 °;
3, aging resistance: can be exposed to ozone, sunlight for a long time, not aging;
4, the lowest coefficient of friction: the minimum coefficient of friction;
5, surface non-stick: known solid material head can not adhere to the surface
6, non-combustible: the air will not burn, in line with strict fire requirements of the place;
7, non-toxic: non-toxic, tasteless, with physiological inertia, no harm to people and the environment.
4. main performance
1. Appearance: smooth, transparent and flat surface
2. Physical and mechanical properties Note: The tensile strength and elongation at break of films with thickness ≤ 0.05mm are slightly lower than the indexes in the table.
5. specifications (unit: mm)
Note: If the user needs other specifications of the film and sheet, can be customized according to the negotiation between the two parties.
6. uses
PFA 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, outstanding surface non-stickiness, low temperature mechanical strength, electrical insulation, air tightness, fold resistance, and very low water absorption and friction coefficient. Its exposure life in the atmosphere can exceed 20 years. Polytetrafluoroethylene ethylene propylene sheets and films are made of polytetrafluoroethylene ethylene propylene resin by extrusion or blow molding. They are suitable for making anti-corrosion, anti-sticking, air-permeable and light-transmitting parts, insulation of electronic and electrical appliances, composite plate interlayer, wear-reducing and wear-resistant parts, seals, insulation parts and medical device parts, high-temperature wires, cable insulation layers, anti-corrosion equipment, sealing materials, pump valve bushings, chemical containers, etc.
