ABSTRACT:
Treated rubber is made from ground rubber and a polyurethane resin. Products made by mixing treated rubber with additional polyurethane resin, molding and curing the polyurethane have higher tensile strengths and/or elongations than similar products made from untreated rubber. The method using treated rubber uses less polyurethane binder to produce products of equivalent strengths. The molding time is also reduced because of the reduced amount of polyurethane binder used.
