Dustless black silicon carbide abrasive grain
Description：
99% SiC black silicon carbide grit produced by a premium reshape milling process. Then the material is washed by acid and fully cleaned by water. So there is much less dust in the grits. In the meantime, it get higher bulk density. That type of black silicon carbide grit is suitable for making abrasive wheels.
Dustless black silicon carbide abrasive grain Properties:
High cleanness with few dust.
High bulk density.
High SiC purity up to 99%.
High hardness, retaining hardness and high wear resistance.
Excellent thermal shock resistance with high thermal conductivity and low linear thermal expansion.
Good particle distribution.
Good ability to withstand the strongest alkalis and acids.
High bulk density black silicon carbide grit Applications:
Semiflex grinding wheel for marble.
Vitrified grinding wheel and SiC cup grinding disc.
Brush buffing wheel.
Nylon polishing wheel for paint remove.
Black silicon carbide Sanding wheel.
Fiber grinding disc.
