Carbon black is an amorphous carbon. It is a black powder with a very large surface area ranging from 10 to 3,000 m2/g. It is a product of carbonaceous materials (coal, natural gas, heavy oil, fuel oil, etc.) that are decomposed under incomplete combustion under conditions of insufficient air. . The term "gas black" made of natural gas, "lamp black" made of oil, and "acetylene black" made of acetylene. There are also "slot black" and "furnace black". According to the properties of carbon black, there are "reinforced carbon black", "conductive carbon black" and "wear-resistant carbon black". Can be used as a black dye for the manufacture of Chinese ink, ink, paint, etc., also used as a reinforcing agent for rubber.
The most widely used model are carbon black N220, N330, N550 and N660 , etc .

Carbon Black Usage:
(1)Carbon black using as Coloring Agent for Ink and Paints
Carbon black has higher tinting strength compared to 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.
(2)Carbon black using as Resin and Film Coloring Agent
Carbon black has high tinting strength and is thermally stable, and therefore it is 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 automobile bumpers, wire coverings and steel pipe linings which require weather resistance in particular.
(3)Carbon black using as Electric Conductive Agent
Carbon black particles have the graphite-type crystalline structure, providing an excellent electric conductivity. Therefore, carbon black is widely used as conductive filler, being mixed in plastics, elastomer, paints, adhesives, 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.
(4)Carbon black using for Electronic Equipment Related Material
Carbon black also provides stable resistance, and therefore is used as electronic equipment related material in various display components, magnetic recording materials, and OA rolls.
Furthermore, Mitsubishi Chemical has been developing carbon black with various combined functions for special applications.
