Product Description

• Brand Name: Haixu abrasive
• Silicon carbide black SiC 400# from China
  
  Description：
  Silicon carbide black SiC 400# from China is a suspension treated black SiC powder. It is of higher purity since its acid washing and water flow sieving process. The Black silicon carbide powder has a sharper granule than that of F grit powder. That shape make grains more easily to glue sand onto coated abrasive base such as cloth and paper and stick tight on those bases.
   
  Silicon carbide black SiC 400# from ChinaProperties:
  Very clean with few impurities such as free carbon, etc.
  High hardness, retaining hardness and high wear resistance.
  Excellent thermal shock resistance with high thermal conductivity and low linear thermal expansion.
  Good particle distribution with narrow particle range.
  Good ability to withstand the strongest alkalis and acids.
