3.Application:
Mainly used for black dyes, Chinese ink, printing ink, paint, etc, also and rubber reinforcing agent.
Carbon black is mainly used in rubber products, the fine particle size of carbon black, the reinforcing performance is superior; The higher the degree of structure carbon black, the stress and set out the higher modulus. Fine particle size of reinforcement are mainly used in tire surface, give the tyres excellent wear resistance. Other parts of the tires, such as the side of the tire, shade cloth layer, take bunch of buffer layer and lined with layer, request compound anti-bending cracked, ozone oxidation resistance, good recovery and low heat performance, the general selection are coarse particle size of the semi-reinforcing type (specific surface area less than 40 m2 / g) furnace black.
