Carbon Black
Application
As an economical means, a small amount of carbon black is generally added to the cable insulation layer and sheath layer. Carbon black not only plays a role in dyeing, but also a kind of light shielding agent, which can absorb ultraviolet light, thereby improving the UV resistance performance of the material. Too little carbon black will result in insufficient UV resistance of the material, and too much carbon black will sacrifice physical and mechanical properties. Therefore, the carbon black content is a very important material parameter of the cable material.
Advantages
1. Surface smoothness
In order to avoid electrical breakdown when the electric field is enhanced, the surface smoothness depends on the dispersion of carbon black and the amount of impurities
2. Anti-aging
The use of antioxidants can prevent thermal aging, and different carbon blacks have different aging properties.
3. Peelability
Peelability relates to a correct peeling force. When the insulating shielding layer is removed, there are no black spots in the insulation. These two characteristics largely depend on the selection of suitable carbon black.
