EXPANDED PTFE SHEET
Products Description
Expanded PTFE gasket sheet is made of 100% expanded P.T.F.E. by using special process that produces a uniform and highly fibrillated microstructure with a great lot of fibers running in multidirection. These create a soft and pliable, yet very tough gasket that has excellent resistance of pressing, creep relaxation and cold flow.
Expanded PTFE sheet possesses universal resistance against common chemicals, except melted alkali metal, fluorine at liquid and gas states. It can be stored without any time limits and can seal uneven and damaged flanges
- full chemical resistance like solid sintered PTFE
- resistance against acids and bases of pH 0 to 14
- UV-resistant
- no aging, unlimited shelf life
- nontoxic, biologically inert
- non flammable
