Physical properties: white or pale yellow, Mohs hardness of 3 - 3.5, density of 4 ~ 4.5a / cm3 J falsePhysicochemical index: BaSO4:BaSO4:90%
Properties: friction material most widely used as a filler, it can make the stable friction coefficient, low wear, especially in the high temperature, it can form a friction boundary layer stability, can prevent the surface abrasion of dual material, thus dual surface more smooth grinding.
