  • Seal material having anisotropic properties
    Patent number: 6517080
    Abstract: A material comprised of two different polymers so that the material exhibits anisotropic properties. The anisotropic properties exhibit hardness and wear resistance along with flexibility. The anisotropic material is made up of a hard segment polymer and a soft segment polymer having contact with each other. This anisotropic material can be used to make seals, which exhibit these same properties and are therefore appropriate for use in high-pressure situations, where they will have a longer life than seals currently on the market.
