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.
