Glass Fiber Filled PTFE Gasket

¡¾ Glass Fiber Filled PTFE Gasket ¡¿

Glass filled PTFE is used to improve the creep resistance of PTFE over all temperature ranges, while still allowing some compression required for sealing in both gaskets and valves. Improved wear behavior is exhibited, while there is little effect on the electrical properties, as glass fiber is an insulator. Glass has an exceptional resistance to water. Glass must be avoided with the use of strong alkalis and hydrofluoric acid.


Glass filled  PTFE is ideal for high load bearing applications, against high hardness surfaces. Examples of
major applications are: bearings and bearing pads, piston rings, valve seats & valve plugs and gaskets.
