Classification and application of carbon black

In rubber products, a certain amount of carbon black can be used to compensate and fill to improve the performance of rubber products, which is called carbon black for rubber. 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 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 a poor reinforcing effect and 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; Black, general purpose carbon black, semi-reinforced furnace black), gas furnace black and warm carbon black are soft carbon blacks.

Uses of carbon black

According to different uses, 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, etc. Widely used in rubber, ink, paint, paint, battery, electronic materials and other industries. Among them, rubber carbon black, pigment carbon black and conductive carbon black are the most commonly used.
