Properties of Conductive Carbon Black
May 29, 2022
Conductive carbon black is a product with good effect and low cost among all conductive fillers, and it is not easy to cause the physical properties of the product to deteriorate.
Large specific surface area
The larger the specific surface area, the smaller the size of carbon black particles, the more particles per unit volume, the easier it is to contact each other to form a network path, so the larger the specific surface area, the better the conductivity.
Good dispersion performance
High structure and soft particle appearance, easy to process and disperse, so that the electrical properties/mechanical properties of the material are balanced, and the final product has a smooth and smooth appearance.
Surface chemical properties
In the production process of carbon black, some active oxygen-containing groups are often formed on the surface of carbon black. The existence of these functional groups affects the migration of electrons and reduces the conductivity. The PH value can be used to characterize this index. Carbon black with few surface functional groups Usually weakly alkaline or neutral.
Excellent electrical conductivity
High-structure carbon black can achieve excellent electrical conductivity with a very low addition amount, and the electrical conductivity is basically unaffected after secondary crushing.
Conductive carbon black products have great flexibility. Metal coating, particle core type, particle size and particle shape can be selected according to different application needs to achieve different conductivity and shielding requirements.
