  • Integrated fluorine gasket manufactured by injection molding for hydrogen fuel cells
    Patent number: 9640807
    Abstract: Disclosed is an integrated fluorine gasket manufactured by injection molding for hydrogen fuel cells. In particular, a fluorine compound having a fluorine content of about 60 to 75 parts by weight based on 100 parts by weight of a fluoroelastomer is disposed in a gasket. The resulting fluorine gasket is integrated with a thin bipolar plate having a thickness of about 200 ?m or less to have a thickness of about 750 ?m or less by injection molding on the thin bipolar plate and by cross-linking.
    Type: Grant
    Filed: December 14, 2012
    Date of Patent: May 2, 2017
    Assignees: Hyundai Motor Company, Donga Manufacturing Corp., E.I. Du Pont De Nemours and Company

  • Silica master batch elastomers filled with organically modified silica for a tire and preparation method thereof
    Patent number: 7846993
    Abstract: The present invention relates to an organic silica master batch elastomer prepared by mixing a conjugated diene based copolymer, a vinyl aromatic copolymer or a mixture thereof prepared by solution polymerization with organically modified silica in which the surface of silica is modified with a particular organosilicon compound and a silane coupling agent in solution. The resultant organic silica master batch elastomer exhibits improved mechanical properties, wear resistance and blending processability, and can provide the effect of extending durability of a tire.
