White carbon black can be used as a filling material in plastic production, which can improve the elastic strength, wear resistance and hardness of plastic thermal stability. In addition, the use of white carbon black for cable can also improve the electrical insulation of the cable, such as methyl vinyl silicone rubber high-voltage wire will use gas phase white carbon black or high-quality precipitated white carbon black. Between the two layers of plastic film is often not easy to separate, bag mouth is difficult to open, and white carbon black is a very useful opening agent. Because it is difficult to mix gas phase nano white carbon black directly with plastic uniformly in the process of use, our company has developed high content of gas phase nano white carbon black masterbatch, which is suitable for the direct addition production of various plastic substrates.
