Features: Polytetrafluoroethylene sheet and turning belt are made from PTFE moulded blanks. It has excellent dielectric properties, does not age, has the best chemical resistance and a wide range of strength. The film is a non-oriented film, which is developed into a directional and semi-oriented film by compression.
Uses: Used for gasket seals and lubricating materials working in various media, as well as electrical insulators that are easy to use at various frequencies. Capacitor dielectric, wire insulation, electrical instrumentation insulation, etc.
