Product Name:Polytetrafluoroethylene gasket
English Name:Polytetrafluoroethylene gasket
CAS No.:9002-84-0
Aliases:PTFE gasket, Teflon gasket, PTFE sealing gasket
Molecular Formula:(C2F4)n
Physical Properties:White waxy translucent solid made of polytetrafluoroethylene (PTFE), with a density of 2.1–2.3 g/cm³, a melting point of approximately 327°C, and a long-term service temperature range of -180 to 260°C. It is insoluble in almost all common solvents and exhibits excellent resistance to strong acids, strong alkalis, oxidants, and organic solvents. It also has a low friction coefficient, non-stick properties, electrical insulation, weather resistance, and aging resistance. Suitable pH range: 0–14 (except molten alkali metals and fluorine at high temperature and high pressure).
Uses:Used as sealing gaskets at flanges of pipes, valves, pumps, reactors, and heat exchangers in chemical, petroleum, pharmaceutical, and food industries, especially for sealing strongly corrosive media. Also applicable to static sealing in vacuum equipment and occasions requiring non-stick or insulating properties.
Technical Specifications:
Working pressure: ≤10 MPa
Service temperature: -180 to 260°C
Applicable pH range: 0–14 (except molten alkali metals and fluorine at high temperature/pressure)
Density: 2.1–2.3 g/cm³
Suitable media: strong acids, strong alkalis, organic solvents, and various chemicals
