PTFE gaskets
PTFE, Unfilled Teflon® Gaskets (Virgin Teflon® Gaskets)
Virgin grade PTFE (Teflon®) gaskets are made from 100% pure material which is used in most general applications. It is extremely soft and formable and is often used for chemical resistant seals and gaskets.
It is made directly from the resin producer and has never been processed into a shape. It possesses the highest physical and electrical insulation properties and has increased resistance to creep (compression) under load. Virgin grade PTFE can be recognized by its whiter color compared to mechanical grade PTFE.
PTFE gaskets are made of synthetic fluoropolymer of tetrafluoroethylene consisting completely of carbon and fluorine. It is innately hydrophobic (repelling water and water-containing substances) and has one of the lowest coefficients of friction against any solid.
PTFE has excellent dielectric properties and provides excellent thermal insulation with an operating temperature range of -200°C to 260°C. PTFE is the most chemically resistant plastic known and is unaffected by most corrosive liquids, vapors, and gases
PTFE gasket products provide outstanding chemical resistance for duties where hygiene and non-contamination are essential.
The PTFE gaskets offer many unique features:
- Outstanding chemical resistance.
- Non-corrosive, non-wetting, non-contaminating and odourless.
- Can work efficiently at temperatures from cryogenic up to +260°C.
- Excellent electrical and thermal insulation in virgin PTFE form.
