HS Code:HS code 280300.
CAS NO. : 10279 - 57 - 9
EINECS NO.: 238 - 878 - 4.
Molecular Formula:White carbon black is amorphous silicon dioxide, and its molecular formula is usually written as SiO2. However, there are usually a large number of hydroxyl groups and other groups on the surface of white carbon black. A more accurate representation may be SiO2.nH2O, where n represents the number of bound water molecules. It is an uncertain value and will vary depending on factors such as the preparation method, treatment conditions, and application environment of white carbon black.
Appearance : typically appears as a fine, white powder,granular.
It is an Amorphous Silica, lacking a well - defined crystalline structure. It has a high specific surface area, which can range from 50 to 600 m²/g depending on the production method and grade. This high surface area contributes to its excellent reinforcing and thickening properties. The particle size can vary, with some grades being Ultrafine Silica Dioxide or even in the form of Silica Nanoparticles or Nano Silica, with diameters in the nanometer to sub - micrometer range.
In terms of hydrophilicity, there are two main types: Hydrophilic Silica and Hydrophobic Silica.Hydrophilic White Carbon Black has a surface rich in hydroxyl groups, which makes it highly reactive with water and other polar substances. In contrast, Hydrophobic White Carbon Black has been treated with organic compounds to modify its surface, reducing its affinity for water and enhancing its compatibility with non - polar materials.

Silica in Rubber and Tires
1）Reinforcement in Rubber: White Carbon Black is widely used as a Silica Filler and Reinforcing Silica in the rubber industry. In Silica in Rubber applications, especially in the production of high - performance rubber products, it can significantly improve the mechanical properties of rubber. When added to rubber compounds, it forms strong interactions with the rubber molecules, enhancing properties such as tensile strength, tear resistance, and abrasion resistance. Rubber Grade Silica is specifically designed to meet the demanding requirements of the rubber industry.
2) Tire Applications: In the tire industry, Silica in Tires or Silica for Tyres has become increasingly important. By using White Carbon Black as a filler in tire tread compounds, it can reduce the rolling resistance of tires, which in turn improves fuel efficiency. At the same time, it also enhances the wet - skid resistance of tires, improving driving safety. Different types of White Carbon Black, such as precipitated silica and fumed silica, can be used depending on the specific performance requirements of the tires.
Other Applications
3)Cosmetics and Personal Care: In cosmetics, White Carbon Black can be used as a thickening agent, absorbent, and opacifying agent. Its fine particle size and high surface area make it effective in controlling the texture and stability of products such as creams, lotions, and powders. In toothpaste, it serves as a mild abrasive and thickener.
4)Coatings and Paints: As a Silica Additive in coatings and paints, White Carbon Black can improve the rheological properties, such as viscosity and thixotropy. It also enhances the scratch resistance, durability, and gloss of the coatings. Hydrophobic White Carbon Black is particularly useful in coatings where water - resistance is required.
5）Food and Pharmaceutical Industries: In the food industry, White Carbon Black can be used as an anti - caking agent to prevent the clumping of powdered food products. In the pharmaceutical industry, it can be used as a flow - aid in tablet manufacturing and as a carrier for drugs in some formulations.
