Teflon film,also known as polytetrafluoroethylene film, is made from suspended polytetrafluoroethylene resin by molding, sintering, cooling into a blank, and then turning and calendering.
The film formed by turning is a non-oriented film, and the non-oriented film becomes a directional film after calendering. The non-oriented film is calendered 1.1-1.8 times to become a semi-oriented film. Teflon film is used as capacitor dielectric, wire insulation, electrical instrument insulation, and sealing gasket. It has high crystallinity, tightly arranged molecular orientation and small void ratio, so the Teflon film has been greatly improved.
1. Chemical stability: Almost all chemical resistance, strong acid, strong alkali or strong oxidizing agent and organic solvent have no effect on it.
2. Thermal stability: cracking temperature is above 400℃.
3. Anti-wear performance: The friction coefficient of PTFE material is low, only 0.02, which is 1/40 of rubber.
4. Self-lubricating: The surface of PTFE material has excellent self-lubricating properties, and almost all sticky substances will not adhere to its surface.
