Pyrite Powder for Abrasive Wheel Bonding

Transportation Hazard Assessment Report 下载

Product Overview

Pyrite (FeS₂) is an essential active mineral filler for resin-bonded abrasive wheels. With moderate Mohs hardness, stable chemical property and good high-temperature lubricity, it can optimize the internal bonding structure of grinding wheels, strengthen the adhesion between abrasive particles and resin, and avoid cracking, thermal deformation and excessive wear during high-speed grinding.
