  • Vibration dampening and/or isolation vulcanizate having high temperature stability
    Patent number: 6197885
    Abstract: Vulcanized rubber parts suitable to dampen vibrations generated by mechanical devices are disclosed. The parts are based on a cured composition comprising one or a mixture of a diolefin polymers, e.g., natural rubber, a halogenated copolymer of a C4 to C7 isomonoolefin, e.g., isobutylene, and a para-alkylstyrene, filler and a curing system. The vulcanized parts exhibit improved aging and high temperature resistance and reduced deterioration of dynamic properties after long term exposure to high temperatures.
    Type: Grant
    Filed: December 4, 1998
    Date of Patent: March 6, 2001
    Assignee: Exxon Chemical Patents, Inc.
    Inventors: Shinichiro Yamashita, Kenneth Odell McElrath, Jr.
  • Motor or engine mount from mixtures of elastomers and halogenated polymers
    Patent number: 5904220
    Abstract: Vulcanized rubber parts suitable to dampen vibrations generated by mechanical devices are disclosed. The parts are based on a cured composition comprising one or a mixture of a diolefin polymers, e.g., natural rubber, a halogenated copolymer of a C.sub.4 to C.sub.7 isomonoolefin, e.g., isobutylene, and a para-alkylstyrene, filler and a curing system. The vulcanized parts exhibit improved aging and high temperature resistance and reduced deterioration of dynamic properties after long term exposure to high temperatures.
