  • Gasket material
    Patent number: 7851555
    Abstract: A gasket material comprising polytetrafluoroethylene (PTFE) and a thermoplastic polymer have a melting point lower than the melting point of PTFE. Preferred thermoplastic polymers comprise fluorinated thermoplastic polymers, and most preferred fluorinated thermoplastic polymers comprise fluorinated ethylene propylene and perfluoroalkoxy copolymer. The PTFE component preferably comprises full density PTFE, and a filler material may optionally be added. The PTFE component is present in the gasket material in an amount from approximately 50% to less than 100%, based on the total weight of the gasket material, and the thermoplastic polymer is present in an amount from greater than 0% to approximately 20%, based on the total weigh to the gasket material.
    Type: Grant
