Modified polytetrafluoroethylene gaskets
PTFE (Polytetrafluoroethylene) gasket is a type of sealing gasket that is widely used in various industries for its excellent chemical resistance, thermal stability, and low friction properties. PTFE is a synthetic fluoropolymer of tetrafluoroethylene and is known for its non-stick properties and resistance to corrosion.
