HG--1 type special conductive carbon black is composed of shell-like high-chain structure. After special treatment, the product has a primary structure particle diameter of 7 nm, larger than surface area and high dispersibility. Due to the mesh structure formed by floe aggregates, it is itself With special conductivity, specific resistance 0.20kΩNaN, PH value 6.0, now widely used in conductive rubber, plastic, anti-static pipe, anti-static fuel tank, cable PVC, EVA shielding materials and other materials that need to be mixed with conductive materials .
