Gehaertete Polyurethan-Massen

摘要

A cured polyurethane composition prepared by mixing a particulate polyfluorohydrocarbon resin with a liquid polyurethane prepolymer and curing the said prepolymer with a curing agent. The cured polyurethane composition has utility in power transmission belts and particularly power transmission belts of the V-type, and other relatively flat-type belts which operate in conjunction with pulleys or sprockets and are subject to relatively severe flexing during their operation.
