Precipitated silica is widely used as filler and filler for rubber and plastics.
In resin matrix composites, white carbon black particles can be dispersed fully and evenly into resin materials, so that the strength, toughness and ductility of epoxy resin are greatly improved, and the wear resistance and material surface finish are improved, and the aging resistance is improved.
So as to improve the properties of resin based materials.
If the white carbon is added to the ordinary rubber, the strength, wear resistance and aging resistance of the product will reach or exceed the top grade rubber products, as you know the color will remain unchanged for a long time.
