Pyrolytic carbon black is a product generated through pyrolysis technology. It is called pyrolytic carbon black because it differs from traditional carbon black production methods. According to electron microscope observations by the Shanghai Chinese Academy of Sciences and tests conducted by the National Carbon Black Quality Supervision and Inspection Center, the average particle size of pyrolytic carbon black is 40–50 nm, and its aggregates are similar to GPF carbon black. Due to its ash content of 14±2%, primarily composed of silica, cobalt salts, and zinc compounds, it exhibits unique chemical and physical properties, including a high degree of crosslinking.
