Graphite powder for rubber and plastics can exert its functions of high temperature resistance, abrasion resistance and corrosion resistance, so that the rubber products and plastics products can be used in complex environments such as high temperature and severe friction in industry for a longer life and a wider range of applications. Different rubber and plastics products need different specifications of graphite powder, and appropriate size of graphite powder for rubber and plastics can play the role of rubber and plastics products. The role of toner in rubber and plastics is very important.
