PTFE Envelope Gasket

Polytetrafluoroethylene (PTFE) envelope gaskets are composite gaskets, consisting of a core material such as CNAF wrapped with a sleeve of PTFE. This hybrid gasket possesses the chemical resistance of PTFE as well as the strength and properties of the core insert material. Superior chemical resistance means that process contamination is prevented, and the highest level of hygiene is maintained. PTFE envelope gaskets are also non-corrosive, non-wetting, non-contaminating and odourless.

Applications

PTFE envelope gaskets are commonly used in the food and process industries where the preservation of media purity is essential.
