Carbon black

Carbon black is one of the main raw materials used in the production of tyres and other rubber products. It increases their durability and resistance. Carbon black is also a key filler reinforcing natural rubber. It improves the durability of the rubber compound. It is also used in the production of: tyres (perfect reinforcement of rubber), dyeing concentrates (used in manufacturing), packaging (plastics industry), films, pipes, printer toners, paints and varnishes, resin dyes, hoses, conveyor belts, washers, and as a main component of rubber compounds.

We offer carbon black from Russia, Ukraine and China. Available types:
