Abstract
Disclosed is a sealing element and a method of manufacture. The sealing element has a sealing surface for providing a seal against a contact surface. A sintered PTFE film is coupled to the elastomeric body, and defines the sealing surface, which is of particular suitability for a dynamic seal. The sealing film comprises a lubricious particulate material.
