Natural gas semi-reinforced carbon black (carbon black) is a high-purity, coarse-grained, moderately structured carbon black product produced through combustion cracking in large-chamber furnaces. Many properties of this product are similar to those of spray carbon black (carbon black), and in cases where spray carbon black (carbon black) severely pollutes the environment, natural gas carbon black (carbon black) is replacing it due to its ease of control, high production volume, and low cost. It is used in many auto parts and machine tool accessories, and is manufactured through scientific formula design to create rubber products with the characteristics of spray carbon black (carbon black).
