Abstract
Core particles produced in situ or introduced as preformed core particles are coated with a layer of carbon. Non-carbon as well as some carbon-based core materials can be utilized. The resulting carbon coated particles can find applications in rubber products, for instance as reinforcement for tire components.
Claims12
A rubber composition or a rubber article comprising carbon-coated particles, wherein the carbon-coated particles comprise a non-carbon core, a reclaimed pyrolysis carbon core, or a plasma CB core coated by a carbon layer, wherein the carbon-coated particles have a STSA within the range of from about 5 to about 275 m2/g and a COAN within the range of from about 40 to about 150 cc/100 g.
