Carbon black manufacturers, conductive carbon black is a large surface area of material, so there is some moisture absorption. Moisture absorption in conductive carbon black is mainly determined by the size of the surface area. Measures can be stepped up to reduce the hygroscopicity of products, especially during packaging, storage and transport. Because moisture (moisture content) is too high will cause trouble to the process, so some varieties of conductive carbon black are required special packaging.

Powdered pigmented conductive carbon black or granular pigmented conductive carbon black for a given plastic blend depends on the type of dispersion and the characteristics of the resin, but the processing power is also a very important factor, and most of the dispersion equipment can play the role of shear Shear, sufficient to granular uniform.

It is generally believed that carbon black manufacturers analyze that the conductive carbon black can be explained by the conductive energy band and the tunnel effect. In the conductive carbon black filled polymer, the electrical conduction is along the contacted particles or separated into small gaps . The average internal aggregation distance is affected by many parameters, including concentration, structure, size and shape of aggregate, size distribution, mixing effect, temperature, and the like.

Carbon black manufacturers, according to the system of carbon black, raw materials can be divided into different types, suitable for conductive fillers is only part of them must have some basic characteristics, such as large specific surface area, capture less electronic impurities, the degree of crystallinity So good
