Carbon Black

Polykem factory supplies Carbon Black (CAS 1333-86-4), a fine black powder used as a reinforcing filler, pigment and conductive additive in rubber, plastics, coatings and ink systems. It is available in different grades including rubber grade, pigment grade and conductive grade, with performance varying according to particle size, structure and surface area.

It can help improve mechanical strength, wear resistance, UV stability and color performance depending on the formulation system. Grade selection is typically based on application requirements such as reinforcement level, dispersion behavior and conductivity demand.

Polykem can provide COA, TDS and SDS for quality review and technical evaluation. Free samples are available for customers testing new formulations or evaluating alternative suppliers before bulk purchase.

Product Parameter

The differences mainly lie in surface area (or particle size), aggregate morphology, mass distribution and chemical composition of particles and aggregates.

Product Grades

Carbon Black is broadly classified into three main grade directions based on particle size, surface area and intended application. The right grade depends on the performance requirement of the final product. Dotachem can supply different grades including N220, N330, N550 and N660 for rubber, plastics, coatings and conductive applications.

N220 – High reinforcement, suitable for tires and high-wear rubber products

N330 – General-purpose grade, widely used in tire and rubber compounds

N550 – Medium reinforcement, used in rubber products requiring balance of strength and processing

N660 – Low reinforcement, suitable for extrusion rubber, hoses and general industrial rubber applications

Key Selection Parameters

When selecting Carbon Black grades, customers typically evaluate several key parameters that determine final performance in rubber, plastics and coating systems. These parameters are directly related to reinforcement strength, dispersion behavior and end-use performance.

Particle Size

Particle size affects reinforcement level and color intensity. Smaller particle size generally provides higher reinforcement and stronger tinting performance.

Surface Area

Surface area is closely related to reinforcing ability and interaction with polymer systems. Higher surface area usually results in better mechanical strength and wear resistance.

Structure

Structure describes the degree of aggregate formation. Higher structure grades typically provide better reinforcement and conductivity performance in rubber and conductive applications.

Oil Absorption (DBP Value)

DBP absorption reflects the void volume between carbon black aggregates, which influences processing behavior, viscosity and dispersion in rubber compounds.

Applications

Rubber - Used as a reinforcing filler in tires, belts, hoses and seals to improve strength, wear resistance and durability.

Plastics - Used for black coloration and UV protection in pipes, cables, packaging materials and engineering plastics.

Coatings - Provides deep black color, tint strength and weather resistance in industrial coatings and protective paints.

Inks - Used in printing inks to improve optical density, color depth and stability.

Conductive Applications - Used in conductive and antistatic materials such as cables, electronic components and functional plastics.
