ABSTRACT:
A rubber molding composition comprising cured rubber scrap (as from automobile tires), a liquid, sulfur-curable polymeric binder, and a curing agent for the polymeric binder. The composition employs from about one to about five parts by weight of the polymeric binder per 100 parts by weight of the scrap rubber. The thus treated rubber scrap may be used in large proportions as a filler or extender for uncured rubbers.
