Rubber Carbon Black (Carbon Black) N990 is a variety with larger particle size among all carbon black types, 200-500nm. Earlier on, it was later discovered that natural gas rubber carbon black has high filling capacity, excellent elasticity of the rubber compound, and superior permanent deformation resistance, leading to its extensive use in automotive, machine tools, and other rubber products. The price has also increased with rising demand and higher natural gas prices.

Physicochemical properties: This product has low specific surface area and structure, with almost no organic functional groups on the surface, resulting in excellent chemical and heat resistance. It is a granulated product with soft particles, easy dispersion, and good fluidity.

Uses: Used as a filler in rubber or plastics, and also in the metallurgical industry as a raw material for carbide products or high-temperature insulation materials, reducing agents, etc.
