EXPANDED PTFE TAPE
Expanded PTFE Sheet/Gasket
I、Features
Polytetrafluoroethylene is a new type of polymer materials. Polytetrafluoroethylene resin by special processing methods. White, flexible and flexible, with a network of fine fibers connected to form a network of these fine fibers to form numerous pores, the expanded PTFE can be arbitrary bending (over 360 degrees), the expansion of polytetrafluoroethylene Has a good anti-chemical, anti-wear properties and extremely high temperature, low temperature capability, ideal for industrial liquid seal.

Skived PTFE sheet is manufactured by technology of compacting, sintering, rotary cutting with PTFE granular resin. As PTFE has a very low co-efficient of friction, so the surface of skived teflon PTFE sheet has similar friction levels to ice. Skived teflon PTFE sheet can work at -180° C ~+260° C and is the best electrical insulator of all known plastics.Skived Sheet0.00Skived PTFE sheet is manufactured by technology of compacting, sintering, rotary cutting with PTFE granular resin.
