high loading level

N990 Carbon black is a kind of thermal black.
Carbon black N990

It's made by thermal decomposition of nature gas at low temperature.

Since it has large particle size and low structure, high loading level could be achieved in rubber. The rubber filled with thermal black has good processing properties and low hardness, decrease dispersion time and increase the fluidity of compound.

Applications:
carbon black for rubber,It used as filler for rubber and plastics, higher temperature insulation materials, etc.
