  • Patent number: 7976955
    Abstract: The rubber compositions described herein have been found to have an exceptionally long life as a spring-biased actuator diaphragm material that maintains its position compressed, e.g., bolted, between opposed flanges, while maintaining excellent compressibility, low temperature flexibility, hydrocarbon resistance, abrasion resistance and mechanical strength. The compositions include a copolymer rubber component; a plasticizer for the copolymer rubber; a vulcanizing agent for the copolymer rubber; a silica filler; and a coupling agent, such as a silane coupling agent, capable of coupling the silica filler to the copolymer rubber.

  • Publication number: 20110166262
    Abstract: A process for forming a compatibilized silica and nitrile polymer blend in latex form is described herein. The process can include treating a silica with a coupling agent in aqueous suspension to form a compatibilized silica slurry. The coupling agent can have the capacity of chemically reacting with the surface of the silica to bond the coupling agent thereto. The process can include blending at least a portion of the compatibilized silica slurry into a styrene butadiene polymer latex, forming a silica styrene butadiene polymer latex, and blending at least a portion of the compatibilized silica slurry into an acrylonitrile butadiene polymer latex, forming a silica acrylonitrile butadiene polymer latex. The process can include blending the silica styrene butadiene polymer latex with the silica acrylonitrile butadiene polymer latex, forming the compatibilized silica and nitrile polymer blend.
