Upgraded pyrolyzed carbon black (CBp) from waste tires and scrap rubber as reinforcing filler in rubber compounds

摘要

Attempts to commercialize pyrolysis of scrap rubber have been unsuccessful because the quality of the quality of the heterogeneous pyro-char was not commercially competitive as a reinforcing filler with virgin carbon black.Ongoing developments integrating state-of-theart thermal and mineral processing technologies have produced an upgraded pyrolyzed carbon black that has competitive reinforcing properties to virgin carbon black in various rubber compounds.
