Detail

① Conductive Carbon Black
Conductive carbon black is a high-performance carbon black that can give materials better strength, toughness and other technical indicators. The resistance coefficient is much smaller than that of ordinary carbon black. The conductive network formed by adding insulating polymers (plastic, rubber) significantly reduces the volume resistivity of plastics and rubber, which were originally insulators, and can give products a conductive or anti-static effect. It is characterized by small particle size, large and rough specific surface area, high structure, high purity, and easy dispersion.
Conductive carbon black can be used in power cables and shielding materials, and can also be used as a raw material for dry batteries. It has broad application prospects in aerospace, national defense, military industry, electric vehicles, wireless communications, consumer electronics and other fields.
② Pigment Carbon Black
Pigment carbon black is a carbon black for coloring pigments. According to the coloring strength (or blackness) and particle size, it is generally divided into high pigment carbon black, medium pigment carbon black, ordinary pigment carbon black and low pigment carbon black. It is mainly produced by the contact method and oil furnace method. The blackness of pigment carbon black is directly related to the particle size of the carbon black. The smaller the particle size, the larger its surface area, and the higher the blackness of the carbon black. Pigment carbon black is mainly used in plastic masterbatch, chemical fiber dyeing, paint ink, coating and other industries.
During the reporting period, the company gradually strengthened the research and development, production and sales of special carbon black. Special carbon black uses the dyeing properties, electrical conductivity and UV resistance and aging resistance of carbon black, and is used in industries such as inks, coatings, color masterbatches, and cable shielding materials.
