Pyrolytic carbon black produced by asphalt and the company into an average particle size of 40 ~ 50 nm, aggregation and GPF carbon black are similar, because ash is 14 + / - 2%, and silicon oxide, cobalt salts and zinc is given priority to, so performance is unique in the chemical and physical properties, a higher degree of crosslinking and diffusivity. Similar to N550 have the strengthening effect of (tensile strength), similar to N772 modulus value (and stress), similar to N330 tear strength. Therefore pyrolysis carbon black in rubber formula, not only has good filling reinforcing effect, and can improve the uniformity of the carbon black dispersion of mixing rubber, improve the processing performance of rubber tire, so nylon bias tyre pyrolysis carbon black has been applied in the inner fabric glue, outer layer cord fabric rubber, tire rubber, rubber and rubber inner lining layer, such as formula, without a change in the original formula of other conditions, chelating agent with 20-30 quality replacement 772 conventional carbon black N550 /, does not affect the quality of tire. In addition, pyrolysis carbon black is widely used in cable, tape, seals, rubber roller and other rubber products.
