Alternative Name: Gasket DN25 PN40 PTFE FF, PTFE sealing gasket, flat PTFE flange gasket, thermal insulation gasket, steel flange gasket.
Information
Gasket DN25 PN40 PTFE FF offers outstanding chemical and thermal resistance unmatched by most thermoplastics. Its exceptional chemical resistance results from the strong carbon-fluorine molecular bond, allowing reliable performance even at elevated temperatures.
In addition to applications in the food processing and chemical industries, PTFE is also widely used in electrical engineering due to its excellent high-frequency insulation properties.
PTFE is virtually unaffected by most solvents, with fluorine and certain fluorine compounds being among the few exceptions.
