  • Composite, high temperature, dynamic seal and method of making same
    Patent number: 8075000
    Abstract: A composite, dynamic seal suitable for use in a high temperature environment and method of making same. The dynamic seal includes a resilient, generally ring-shaped seal body having a first layer formed of a first resilient sealing material and a second layer formed of a second resilient sealing material. The first and second layers are preferably molded and cured together simultaneously and chemically cross-linked to each other. The first resilient sealing material is selected for its wear resistant dynamic properties and the second resilient sealing material is selected for its compression set resistant properties. Preferably, the first resilient sealing material is tetrafluoroethylene and propylene copolymer and the second resilient sealing material is fluorocarbon rubber. The first and second resilient sealing materials have compatible cure systems, preferably peroxide cure systems.
