  • Elastomeric compounds containing recycled materials and silica
    Patent number: 8329810
    Abstract: A recycled elastomeric composition that can include a natural rubber, a synthetic elastomeric polymer, or combinations thereof is described herein. The synthetic elastomeric polymer can include butadiene and styrene. The recycled elastomeric composition can also include a compatibilized silica with a coupling agent, a crumb rubber, a carbon black, a filler, and an extender oil. Articles comprising the recycled elastomeric composition can include: floor mats, tires, belts, rollers, footwear, wire or cable jacketing, roof edging, tubulars, and marine impact bumpers.

  • NITRILE BUTADIENE STYRENE TERPOLYMERS
    Publication number: 20110166264
    Abstract: An elastomeric thermoplastic non-vulcanized terpolymer composition formed from acrylonitrile, styrene, and liquid 1,3-butadiene is disclosed herein. The terpolymer can have from 20 percent by weight to 50 percent by weight of the acrylonitrile, from 0.5 percent by weight to 20 percent by weight of the styrene, and from 30 percent by weight to 79.5 percent by weight of the butadiene. The acrylonitrile can be cross-linked to the styrene. The thermoplastic non-vulcanized terpolymer can include fillers, UV stabilizers, and plasticizers. Also disclosed is an article formed by the elastomeric thermoplastic non-vulcanized terpolymer and a process for making the composition.
