  • UV curable elastomer composition
    Publication number: 20010044480
    Abstract: Ethylene copolymer elastomer compositions, acrylate rubber compositions, nitrile rubber compositions, fluoroelastomer compositions, and chlorinated elastomer compositions are provided which are curable by exposure to UV radiation. The compositions are particularly suited for production of elastomeric seals using hot melt equipment and a gasketing in place technique.

  • Nitrosamine-free curing of chloroprene/sulfur copolymers
    Patent number: 5483006
    Abstract: Chloroprene/sulfur copolymers peptized either by xanthogen sulfides alone or in combination with mercaptobenzothiazole in an alkaline dispersion are cured in the presence of N-cyclohexyl-2-benzothiazyl-sulfenamide or mercaptobenzothiazole disulfide as an accelerator and in the absence of nitrosamine forming additives. Metal oxides are the usual curing agents.
