PTFE Gasket Material

This gasket material is made with 100% Virgin PTFE and uses Barium Sulfate as the filler.

This PTFE sheet is manufactured by a unique process that structures the composition into fibers that overcome creep relaxation and/or cold flow. Cold flow is a problem associated with plain PTFE sheet.

It is suitable for use in aggressive chemicals including sodium and potassium hydroxide, hydrogen and aluminum fluoride, chrome plating solution and vinyl compounds.
