Sulfex Red

Sulfex Red, distributed by Washington Mills, is prepared from carefully selected pure monocrystalic iron pyrites (FeS2). Sulfex Red 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 Red 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.
