The specific applications of hydrophobic white carbon black in the rubber industry are mainly reflected in the following aspects:
1. Improve the mechanical properties of rubber
Hydrophobic white carbon black, through its high specific surface area and surface activity, can form a good physical cross-linking network with rubber molecules, thereby significantly improving the tensile strength, elastic modulus, and wear resistance of rubber products. In addition, the addition of hydrophobic white carbon black can increase the hardness and compressive properties of rubber, making it more suitable for high load rubber products.

2. Improve the weather resistance and thermal stability of rubber
Hydrophobic white carbon black has good chemical stability and antioxidant properties, which can effectively prevent the aging and deterioration process of rubber materials under harsh environmental conditions such as sun exposure and oxidation. Its high specific surface area and adsorption capacity enable it to capture and neutralize free radicals, reduce the occurrence of harmful oxidation reactions, and thus delay the aging rate of rubber products. In addition, hydrophobic white carbon black can improve the thermal stability of rubber and resist desulfurization and decomposition processes at high temperatures.

3. Optimize the processing performance of rubber
The hydrophobicity of hydrophobic white carbon black improves its dispersibility in the rubber matrix, reducing heat generation and energy consumption during the mixing process. Compared with traditional hydrophilic white carbon black, hydrophobic white carbon black has a more uniform dispersion in rubber, which can avoid particle aggregation and improve the uniformity and consistency of rubber products.

4. Improve the surface properties of rubber
The hydrophobicity of hydrophobic white carbon black can improve the surface gloss and hand feel of rubber products. In addition, its surface activity can also regulate the electrical and thermal conductivity of rubber, making it more widely used in fields such as electronic rubber.

5. Used for the production of green tires
The application of hydrophobic white carbon black is particularly prominent in green tires. It can significantly reduce the rolling resistance of tires while maintaining rubber wear performance, while improving wet skid resistance. This balance of performance is of great significance for the industrialization of green tires.

6. Application of Wet Mixing Technology
Wet mixing technology is an important progress in the rubber industry in recent years, and the application of hydrophobic white carbon black in it has also attracted much attention. Through wet mixing, hydrophobic white carbon black can be more evenly dispersed in the rubber matrix, thereby improving the mechanical properties and durability of rubber products. For example, the white carbon black/natural rubber masterbatch produced by Zhongce Rubber Group using wet mixing technology has significantly improved mechanical properties and significantly reduced heat generation and hysteresis losses.

In summary, hydrophobic white carbon black has a wide range of application prospects in the rubber industry, which can significantly improve the performance and processing efficiency of rubber products. It is an indispensable and important material in the rubber industry
