Non-rubber carbon black (special carbon black)
① Conductive carbon black
Conductive carbon black is a high-performance carbon black, which can give the material better technical indicators such as strength and toughness. The resistivity is much smaller than that of ordinary carbon black. The conductive network formed by adding insulating polymers (plastics, rubber) makes the original The volume resistivity of plastics and rubbers that are insulators is significantly reduced, which can provide products with conductive or antistatic effects. 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 raw material for dry batteries. It has broad application prospects in aerospace, defense and military industry, electric vehicles, wireless communications, consumer electronics and other fields.
②Pigment carbon black
Pigment carbon black is carbon black for coloring pigments. According to color strength (or blackness) and particle size, it is generally divided into four types: high pigment carbon black, medium pigment carbon black, ordinary pigment carbon black and low pigment carbon black, mainly by contact method And oil furnace method production. The blackness of pigment carbon black is directly related to the particle size of carbon black. The smaller the particle size, the larger the surface area and the higher the blackness of carbon black. Pigment carbon black is mainly used in industries such as plastic masterbatch, chemical fiber dyeing, paint, ink, and coating.
During the reporting period, the company gradually strengthened the research and development, production and sales of special carbon black. Specialty carbon black uses carbon black's dyeing properties, electrical conductivity, anti-ultraviolet and anti-aging properties, and is used in ink, paint, color masterbatch, cable shielding materials and other industries.
The special carbon black produced by the company mainly includes 3 series and 7 types of products. The related product types, product performance and application fields are listed as follows:
