Product Description

Carbon black, also known as pigment black 7, is an amorphous carbon. Light, loose and very fine black powder with a very large surface area ranging from 10-3000m2/g, it is the product of incomplete combustion or thermal decomposition of carbon-containing substances (coal, natural gas, heavy oil, fuel oil, etc.) in conditions of insufficient air.

Carbon black exists in the form of colloidal primary particles and aggregates that resemble spheres. It is generally processed (granulated) into granular products with a diameter of 1 to 2 mm. It is also available in powder form, with different processing techniques and different appearances.

Application

 

1. Rubber Carbon black is used as an important reinforcing agent in rubber products, it improves the abrasion properties of tyres, increases the tensile strength and tear strength of the rubber, etc. Of the carbon black used in rubber, about 75% is used to make tyres and the rest is used to make hoses, tapes, etc.
2. Ink Carbon black is mainly used in black pigments, and pigmented carbon black is mainly used in printing ink, because the blackness and colour level of pigmented carbon black are much stronger than ordinary carbon black.
3.Plastics Carbon black is mainly used in plastics to protect against UV ageing and to conduct electricity.
In addition, carbon black is also used in synthetic leather, coatings, batteries, printing and dyeing, gunpowder and other aspects have an important role.
