How to choose carbon black for UV resistance and carbon black for conductivity

Anti-ultraviolet carbon black is mainly used in plastics and rubber and plastics, and carbon blacks with medium particle size and slightly higher structure are selected, and their anti-ultraviolet performance is good.

The carbon black for electrical conductivity should choose good electrical conductivity, such as conductive carbon black, acetylene carbon black, etc. Conductive carbon black is a kind of special carbon black, they must have some basic characteristics, such as large specific surface area, less impurities to capture electrons, good crystallinity and so on. According to this characteristic, when choosing conductive carbon black, try to choose carbon black with high structure, large specific surface area, few surface functional groups, weak basic or neutral carbon black.
