The advantages of silica as a filler are mainly reflected in the following aspects:

Reinforcement and modification: White carbon black can significantly enhance the strength and stiffness of materials, while improving properties such as heat resistance, electrical insulation and fire resistance. In plastics, it can be used as reinforcing filler to improve the mechanical strength and tear resistance index of products.

Improve rheology: White carbon black has good dispersion properties and can fill the gaps in the material, thereby improving its fluidity and processing performance, and helping to improve product production efficiency.

Improve durability: Silica black can fill the pores in concrete and increase the compactness of concrete, thereby increasing its compressive strength and tensile strength. At the same time, it can also prevent concrete aging, corrosion and damage, improving durability.

Anti-aging properties: White carbon black can be combined with other ingredients to form a protective layer to prevent the material from being damaged by external factors such as ultraviolet rays and oxidation, thereby extending the service life of the material.

Wide range of applications: White carbon black is not only used in industry, building materials, coatings, plastics and other fields, but can also be used in cosmetics and personal care products to provide soft texture and emulsification effects, and to adjust the rheological properties and transparency of products. In the food industry, it can be used as a thickener, stabilizer and anti-caking agent to improve the texture and taste of food.

It should be noted that silica prepared by different preparation methods has differences in physical and chemical properties and microstructure, so its application effect as a filler will also be different. In practical applications, the appropriate silica type needs to be selected based on specific needs and material properties.
