Parameters

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.
