PTFE Films
Product classification:
Polytetrafluoroethylene (PTFE) turning film is an unoriented PTFE film produced by turning a molded blank, as well as a semi oriented and oriented film produced by re rolling the unoriented film.
SFM-1 (directional): used as a capacitor dielectric, etc
SFM-2 (semi directional, non directional): used for wire insulation, etc
SFM-3 (directional, non directional): used as insulation and sealing gasket for electrical instruments, etc
Product features:
1. Low and high temperature resistance (-180C -+260C)
2. Corrosion and climate resistance
3. High lubrication and non adhesion
4. Non toxic
5. Incombustibility
6. Acid resistant shouting (excluding molten alkali metals)
7. Antioxidant properties
Product Usage:
1. Used in various electronic appliances such as wires, cables, battery electrodes, etc
2. It is also used as a gasket seal and lubricating material in various media, as well as an electrical insulation component used at various frequencies.
