Abstract
Abstract An anti-abrasive, flame-resistant, and noise-suppressant laminate suitable for use with underground scraper conveyors or the like comprising two outer layers of ferrous material having an inner layer of styrene butadiene rubber material vulcanized therebetween. The styrene butadiene rubber material has a durometer of the order of 59, a flame spread index of less than 25 according to ASTM-E162 and a thickness of the order of 1/4 inch. One of the outer layers is of abrasive resistant steel and has a thickness of the order of 1/4 inch. The other outer layer is of 1020 steel and has a thickness of 16 gage.
