KGF Gaskets offer qualitative assortment of Poly tetra fluoro ethylene (F4, PTFE), which are widely used in National defence, Atomic energy, petroleum, wireless, electric machinery and chemical industries etc.

Expanded PTFE Gaskets:-

Offering versatility and convenience in the form of a highly conformable flexible strip is the expanded PTFE gasket by KGF that is used in non-standard range applications. It is also a backup sealing option under non availability of conventional gaskets. Expanded PTFE gaskets are suitable for temperatures ranging up to 250°C and for cryogenic applications like hydraulic systems, water supply systems, ventilation ducts, fan housing, fume ducts, pneumatic systems, engine case doors etc.

PROPERTIES AND APPLICATION

PTFE gaskets are one of the most suitable types of gaskets for a variety of sealing applica_ons and are mostly based on virgin PTFE or filled PTFE. PTFE gaskets provide an extensive range of applicability. PTFE is a fluoropolymer, which features an outstanding chemical resistivity to almost all chemicals, good thermal insulation properties, and useful mechanical and processing characteristics. The above-mentioned PTFE features can be usefully applied in PTFE gaskets. They can be mostly used in valve seats, bearings, requested to resin sliding and chemicals, elastic band for un-lubricated compressors, O-rings where elastomers cannot withstand. An extended range of improved mechanical and processing properties can be additionally reached by combination of virgin PTFE and different fillers. Different combination offer a variety of different properties described in the following table.
