SULFEX® YELLOW, distributed by Washington Mills, is prepared from carefully selected pure monocrystalic iron pyrites (FeS2). This material consists of finely grained Pyrite crystal splinters, which increases the thermal conductivity, the tensile strength, and the porosity of resin-bonded grinding wheels and cut off wheels. SULFEX® YELLOW improves durability and performance of organic bonded abrasives by reducing the temperature in the contact zone or the work piece and cut off / grinding wheel.
SULFEX® YELLOW is used as a grinding-active filler in resin-bonded grinding wheels and cut off wheels, brake linings, etc. It can be used alone or in combination with other active fillers in organic bonded abrasives.
