Filled PTFE (Teflon®) gaskets are made from PTFE which integrates additives and fillers in order to
improve the performance of the gasket. This improves the gaskets ability to wear and enhances its
unique combination of chemical, physical and electrical properties. Filled Teflon® is the most common
type of PTFE gasket for industrial use as it exhibits improved mechanical strength compared to Virgin
PTFE. Glass, carbon and fiber particles are typical fillers that are used to enhance the mechanical
strength of the gasket depending on the application.
