Among many industrial materials, white carbon black (scientific name: hydrated silica) may not be well-known to the public, but it plays a crucial role in various fields such as rubber, plastics, coatings, cosmetics, and can be called the "hidden champion" of the industrial field.


1、 Basic characteristics of white carbon black


White carbon black is a white, non-toxic, and odorless non-metallic oxide with high specific surface area, porous structure, excellent reinforcement properties, and chemical stability. These characteristics enable white carbon black to significantly improve the physical and mechanical properties of materials, such as enhancing hardness, improving wear resistance, and increasing tear strength.


2、 Application in rubber industry


The rubber industry is the largest consumer area of white carbon black. In tire manufacturing, white carbon black as a reinforcing agent can replace some carbon black, improve the wet grip and rolling resistance of tires, thereby enhancing fuel economy and driving safety. In addition, white carbon black can also improve the wear resistance and anti-aging performance of tires and extend the service life.


3、 Contribution in the plastics industry


In the plastic industry, white carbon black as a filler can increase the volume of plastics, reduce costs, and improve the processing and physical mechanical properties of plastics. For example, adding white carbon black to plastics such as polyethylene and polypropylene can improve their hardness, rigidity, and heat resistance, making them more suitable for manufacturing automotive parts, household appliance casings, and so on.


4、 Performance in Coatings and Inks


White carbon black is mainly used as a thickener, anti settling agent, and thixotropic agent in coatings and inks. It can increase the viscosity of coatings and inks, prevent pigment settling, and improve the leveling and glossiness of coatings. In addition, white carbon black can enhance the weather resistance and chemical corrosion resistance of coatings and inks, extending the service life of coatings.


5、 The wonderful use in cosmetics


In the field of cosmetics, white carbon black is favored for its excellent oil absorption and skin sensation regulation ability. It is often used as the filler of foundation make-up, powder and other cosmetics, which can absorb the oil on the skin surface, maintain the durability of makeup, and give the product a silky and delicate touch.


6、 Future prospects


With the advancement of technology and the improvement of environmental awareness, the application fields of white carbon black will continue to expand. For example, in the field of new energy, white carbon black can be used to prepare high-performance lithium-ion battery separators; In the field of environmental protection, white carbon black can be used as an adsorbent to treat heavy metal ions in wastewater. It can be foreseen that the "invisible champion" of white carbon black will showcase its unique charm in more fields.
