The conductor shielding material is composed of semi-conductive material based on polyethylene and carbon black. It is still widely used in wire and cable. The quality of conductor shielding materials directly affects the quality of cables, and conductive carbon black also plays a key role in conductor shielding materials. Correspondingly, many friends in the carbon black industry do not know much about it. This article will tell you about the relevant knowledge points of conductive carbon black used in conductor shielding materials.
The role of conductive carbon black in conductor shielding materials
Conductive carbon black can impart conductivity or antistatic effect to products, and its role in conductor shielding materials is mainly conductive shielding.
Classification of conductive carbon black for conductor shielding materials
It can be divided into conductive carbon black for inner shielding materials, conductive carbon black for outer shielding materials, and conductive carbon black for cable shielding materials.
Conductor shielding material carbon black ratio formula
100 parts of ethylene-butadiene rubber, 50-120 parts of conductive carbon black, 20-45 parts of plasticizer, 1.0-6.0 parts of vulcanizing agent, 1.0-6.0 parts of co-curing agent, 1.0-10 parts of activator, 0.2-5.0 parts of coupling agent 0.5-5.0 parts of anti-aging agent. The semi-conductive conductor shielding material of this formula not only has low cost, but also has simple components. Of course, the specific use is for reference only.
Through the above knowledge points, everyone has a certain degree of understanding of conductive carbon black for conductor shielding materials, especially its function and classification. Of course, there are still many knowledge points about conductor shielding materials. Other specific content You can read other pages of this website.
