The specific gravity of white carbon black is usually between 2.319 and 2.653, and the specific value may vary slightly due to differences in preparation process and application field. The chemical name of white carbon black is silicon dioxide (SiO2), which is a white, non-toxic, amorphous powder with highly dispersed nano-scale non-metallic material properties.
The specific gravity of white carbon black is affected by the preparation process and application field. For example, the specific gravity of white carbon black prepared by different raw materials or production methods may vary. In the rubber industry, white carbon black is a high-quality reinforcing filler, and its specific gravity directly affects the performance of rubber products. White carbon black with a moderate specific gravity can be better dispersed in the rubber matrix, thereby improving the wear resistance, tear resistance and aging resistance of rubber products.
In addition, other physical properties of white carbon black are also worthy of attention. Its melting point is as high as 1750℃, which allows it to maintain stable performance under high temperature environment. Silica gel also has good reinforcement, anti-slip properties and shoe surface adhesion, so it has broad application prospects in the shoemaking industry.
