Key statement: The present invention relates to a modified crumb rubber particle having carbon to silicon bonds created by the reaction of the unsaturation in the crumb rubber particle and silicon hydride, with or without the use of a catalyst.
At temperatures above 2030F (1110C), Si[O.sub.2] reacts with hydrogen to form silicon hydride. This highly volatile vapor opens channels in the pore spaces in the molding sand.
