Expanded PTFE 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 sheet that has excellent resistance of pressing, creep relaxation and cold flow.
Characteristics :
1. Full chemical resistance like solid sintered PTFE.
2. Resistance against acids and bases of pH 0 to 14.
3. UV-resistant.
4. No aging, unlimited shelf life.
5. Nontoxic, biologically inert.
6. Non flammable.
Application:
Best adaptation on uneven surfaces and affected sealing faces for sealing of stress sensitive material like glass lined steel, glass, ceramic*long lasting gasket solution for extreme aggressive Media
Suitable for use against :
1. Acids Alkalis Corrosive Fluids Oils Solvents
2. For use in the following industries
3. Food & Beverage Pharmaceutical Chemical Petrochemical Distillery
4. Marine Power Generation Paper
