Why is carbon black vulcanized after adding silicone rubber not ripe? According to the manufacturer's technical analysis, it is likely that the purity of carbon black is not high enough and the sulfur content is high, so it is recommended to use acetylene carbon black as silicone rubber packing.
As we all know, acetylene black is a kind of conductive carbon black, with high purity, good thermal conductivity, ash content, low sulfur content, surface water absorption characteristics.
Its low sulfur content is an important reason for its suitability for conductive silicone rubber products, which is related to the vulcanization process of silicone rubber. High purity acetylene black is due to its low sulfur content, which has overcome the problems of poor vulcanization and premature vulcanization in the vulcanization process of silicone rubber.
When we choose carbon black, we can tell the carbon black manufacturers what products we need to make and the physical requirements of carbon black, so that the carbon black manufacturers can give us better Suggestions, so that the quality of our products can be better guaranteed.
