The polymer composition can have a minimum amount of at least ten percent by weight of 15:50 ratio, acrylonitrile to butadiene polymer, with the remainder being compatibilized silica.
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.
