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

Physical Properties of expanded ptfe sheets
Expanded PTFE Sheet is a high performance sheet gasket material made of multi-directionally expanded virgin PTFE. It is a soft, form-in-place gasket material that conforms to almost any sealing surface. It is capable of withstanding a wide range of pressure, temperature and chemical environments. Due to its highly fibrillated microstructure, it has excellent creep resistance compared with other PTFE products.
Typical Application
> Distilleries, petrochemical, food and beverage, pharmaceutical, general chemical, power generation, iron and steel manufacturing, pulp and paper, etc.
