Compositions with Compatibilized Silica Nitrile Rubber Styrene Butadiene Rubber Elastomeric Compounds and/or Recycled Materials

摘要

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 to form a compatibilized silica slurry. The process can include blending the compatibilized silica slurry into a styrene butadiene polymer latex and an acrylonitrile butadiene polymer latex. The process can include blending silica styrene butadiene polymer latex with silica acrylonitrile butadiene polymer latex. A polymer composition of a compatibilized silica in blends of acrylonitrile butadiene polymer and styrene butadiene polymer and a recycled elastomeric composition are described herein. 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 are disclosed herein.
