PTFE Envelope Gaskets
PTFE envelope gaskets consist of a PTFE envelope with a nonasbestos fiber gasket insert.
These gaskets exhibit chemical resistance of the PTFE and strength and resilience of the insert. These gaskets are the best possible solution for aggressive chemicals where the normal fiber gasket should not come in contact with the medium. PTFE has good chemical resistance and is safe to be used with food, hence these gaskets are majorly used in chemical and food industries.
