CSRC produces furnace black in granular form through the cracking, dehygrogenation and nucleation of hydrocarbons. This product is a reinforcement agent which is indispensable to the rubber industry, and is widely used in rubber products. By the reinforcement it can increase the modulus, stiffness and abrasive resistance of the elastomer. The reinforcement mainly results from the carbon gel formation, carbon gel is formed through the creation of an infinite network structure by the carbon black and elastomer molecules; the strength of this crosslinked network structure determines the characteristics of the elastomer matrix. Since the reinforcement action is derived from the molecular interaction of carbon black with elastomer, the particle properties of carbon black are very important, including particle size, DBP structure, moisture content, tinting strength, pH and volatile content. Therefore, it can be classified as ISAF, HAF, FEF, GPF or SRF grades depending on processing requirements.
