Carbon black in rubber, the main function lies in reinforcing and improving wear resistance, reduce the cost. For example, many synthetic rubber butadiene, styrene butadiene must use the carbon black reinforcing, to achieve the ideal of the tensile strength, abrasion, or stretched out.

acetylene black is mainly used in tire as the main products of rubber industry. Tire industry use carbon black accounts for the rubber industry needs more than 80% of the carbon black. Generally to all kinds of motor vehicles (including motorcycle) tire and other rubber products are collectively referred to as "rubber". Rubber carbon black consumed each year about 20% of the rubber with carbon black.

Carbon black is mainly used in rubber, carbon black particle size is fine, the reinforcing performance more superior; carbon black structure degree is higher, the higher stretch stress and modulus. Fine particle size of bolt-on varieties, mainly used in tire surface, giving excellent wear-resisting performance tires. Other parts of the tire, such as sidewall, cord fabric layer, buffer layer and the lining layer beam, anti-bending of request rubber crack, resistant to ozone oxidation and have good resilience and low thermal performance, relatively coarse particle size is generally selected half a bolt-on (specific surface area is lower than 40 m2 / g) furnace black
