Black Pigment(Carbon Black)

Black Pigment (Carbon Black) is a micronized processed product obtained from soot, an organic composition obtained from defective burning of natural gases. Carbon and hydrogen are its constituent elements and it is used in painting industry as a basic black pigment.This pigment is dissolved in resins. It is one of the main factors of equal distribution of organic particles, average size of particles oil absorption amount.It is applied in paint, P.V.C, Masterbatch, granole, wire and cable, tire and plastic industry and also in artificial leather.Carbon blacks are classified in intensely black submicron size pigments, composed of pure carbon and made by the darkest and most finely separated materials known.  Chemically, carbon black composition of hydrocarbons in an open diffusion flame, in a partial combustion chamber, or in a thermal decomposition chamber in absence of air. 


The most popular application of carbon black is in rubber production with two main categories specifically tires and mechanical rubbers such as hoses at automotive belts.


Performance and lifespan of the rubber material is improved by reinforcing properties of carbon black. Its application in rubber is basically divided into and N100 to N900 series blacks where N represents the nitrogen surface area.


Carbon black properties impacts on rubber on the performance of rubber by its higher the tensile strength, smaller particle size and reduced rebound and dispersibility as well as abrasion resistance.


As the porosity picks up, the tear strength and conductivity increase with the consecutive decrease in rebound. As the surface activity increases the abrasion resistance increases along with an increase in the rebound and modulus.

Rubber Industry

Carbon black is having a much higher tinting strength in comparison with iron black or organic pigments, and is widely used for newspaper inks, printing inks, India inks, and paints.


Carbon black is also used as black pigment for inkjet ink or toners.

Ink and Paint

Due to its high tinting strength carbon black is thermally stable and suitable for coloring resins and films that are heat-formed.


Carbon black is also excellent for absorbing ultraviolet light, providing both a superb resistance against ultraviolet rays and a coloring effect when just a small amount is mixed with resins.


Carbon black is widely used for general coloring for resins and films. Resins with carbon black are used in wire coverings, automobile bumpers and steel pipe linings which require weather resistance in particular.

Resin and Film

Due to graphite-type crystalline structure of carbon black particles, it provides an excellent electric conductivity. Therefore, carbon black is widely used as elastomer, conductive filler, being mixed in plastics, adhesives, paints, films and pastes.


Fuel caps and fuel-introducing pipes of automobiles, for example, are required of electric conductivity for preventing static. Therefore, carbon black is used as an excellent antistatic agent.

Conductive Agent

Carbon black also provides stable resistance, and therefore is used as electronic equipment related material in various magnetic recording materials, display components and OA rolls.


Furthermore, Mitsubishi Chemicals has been developing carbon black with various combined functions for special applications.


Other applications of carbon black are refractories, fibers, electronics, metallurgy, batteries, cosmetics, etc.
