PYRICAL®

PYRICAL®, distributed by Washington Mills, is prepared from carefully selected pure monocrystallic iron pyrites (FeS2). PYRICAL® 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. 

PYRICAL® 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. PYRICAL® is a non-toxic active filler based on a mix of minerals (mainly iron pyrite) developed for bonded abrasives. Similar to Sulfex Rosso, it is more basic; with a pH between 6 and 8, it is ideal to help polymerization of resins.
