Carbon black (also called carbon black) is a colloidal particle similar to a sphere formed by incomplete combustion or thermal cracking of hydrocarbon compounds (liquid or gaseous). It exists in the form of aggregates and appears as pure black powder or granular form. The particle size, structure and surface activity of products vary greatly depending on raw materials, manufacturing methods and production processes. The main component of carbon black is carbon, and also contains trace amounts of hydrogen, oxygen, ash and moisture.
What are the functions of carbon black?
Mainly used as reinforcing agent and filler for rubber, its consumption is about half of rubber consumption. Rubber carbon black accounts for 94% of the total carbon black. About 60% of this is used in tire manufacturing. In addition, it is also used as a colorant for inks, coatings and plastics, and as a UV-shielding agent for plastic products. It is also an important additive in many other products, such as electrodes, dry batteries, resistors, explosives, cosmetics and polishing pastes.
Carbon black for rubber is used in the tire industry, rubber seals, shock absorbers, etc. A certain amount of carbon black can be used to reinforce and fill rubber products. To improve the performance of rubber products.

In rubber products, a certain amount of carbon black can be used to compensate and fill to improve the performance of rubber products. It is called rubber carbon black. It accounts for about 95% of the total carbon black. In the rubber industry, in order to express the reinforcing effect of carbon black on rubber and its application site on tires, it is also customary to divide carbon black into two categories: hard carbon black and soft carbon black. The former has a good reinforcing effect on rubber, while the latter has poor reinforcing effect and has a filling effect to a large extent. Most of the oil furnace carbon black (super wear-resistant furnace black, medium-super wear-resistant furnace black, high wear-resistant furnace black, fine particle carbon black) belongs to hard carbon black; a small part of oil furnace carbon black (quick-pressed furnace carbon Black, general carbon black, semi-reinforced furnace black), gas furnace black and heated carbon black are soft carbon blacks.
Use of carbon black
Carbon black is usually divided into pigment carbon black, rubber carbon black, reinforcing carbon black, insulating carbon black, spray carbon black, colored carbon black, Metallurgical carbon black, conductive carbon black and special carbon black can be widely used in rubber, ink, coatings, paints, batteries, electronic materials and other industries. Among them, rubber carbon black, pigment carbon black, and conductive carbon black are the most commonly used.
