Among many chemical materials, white carbon black (scientific name: silica aerogel or precipitated silica) has quietly become the "invisible champion" of many industries due to its unique physical and chemical properties. As a high-performance inorganic non-metallic material, white carbon black not only has extremely high specific surface area and excellent adsorption performance, but also exhibits good chemical and thermal stability. In the rubber industry, as a reinforcing agent, it significantly improves the wear resistance, tear resistance, and rolling resistance of tires, promoting the development of green tires; In the fields of coatings and inks, white carbon black is used as a thickener and anti settling agent to improve the leveling and storage stability of products; In addition, in industries such as medicine, food, and cosmetics, white carbon black also plays an indispensable role, such as serving as a drug carrier, food additive, and oil absorbing ingredient in cosmetics. With the advancement of technology, the application fields of white carbon black are constantly expanding, becoming an important force in promoting industrial upgrading.
