1、 Application of White Carbon Black
rubber industry
White carbon black is an important filler and reinforcing agent in the rubber industry. It can significantly improve the aging resistance, wear resistance and strength of rubber, and at the same time, make rubber have better compounding and curing effect. White carbon black is particularly suitable for manufacturing high-performance tires, which can improve tire grip and wear resistance.

Coatings and Ink Industry
White carbon black is commonly used in coatings and inks due to its high specific surface area and excellent dispersibility. It can increase the adhesion, transparency, and extensibility of pigments, while improving the printing effect and weather resistance of inks.

Plastic industry
White carbon black can increase the strength, impact resistance, and weather resistance of plastic products. In addition, it can also be used to make plastic electronic components, improving the conductivity and anti-static performance of the product.

Food and pharmaceutical industry
White carbon black is used in the food industry as an anti caking agent, stabilizer, and thickener to improve product texture and taste. In the field of medicine, it can be used as a filler for tablets and capsules.

Other fields
White carbon black can also be used as a carrier or diluent in pesticides and fertilizers, as a friction agent and thickener in toothpaste, and as a dispersant or matting agent in coatings.

2、 Application of Carbon Black
rubber industry
Carbon black is a commonly used reinforcing agent in rubber products, especially in tire manufacturing, as it can significantly improve the strength and wear resistance of rubber. In addition, carbon black can also be used for rubber seals and other rubber products.
Coatings and Ink Industry
Carbon black is widely used in coatings and inks due to its black appearance and good dispersibility, providing high coverage and color concentration.
Electronic field
Carbon black has good conductivity and is commonly used in fields such as battery materials, conductive plastics, and supercapacitors.
Other fields
Carbon black is also used in the production of black dyes, pigments, and as an adsorbent in the field of environmental protection.

3、 Comparison between White Carbon Black and Carbon Black
Characteristics/Application Fields White Carbon Black Carbon Black
Main components: silicon dioxide (SiO ₂), carbon (C)
Color White or Light Grey Black
High specific surface area (>1000 m ²/g) and low (100-500 m ²/g)
Chemical properties: Hydrophilic, with hydroxyl groups on the surface and oleophilicity, chemically stable
The rubber industry improves wear resistance and aging resistance, improves strength and wear resistance
Coatings/inks provide transparency and dispersibility, as well as coverage and color concentration
Used in the field of electronics for insulating materials and conductive materials
Environmental benefits: The production process is environmentally friendly and can replace traditional pigments with strong conductivity, but the energy consumption in the production process is relatively high

4、 Conclusion
Although white carbon black and carbon black overlap in certain application fields, their characteristics determine their respective advantages. White carbon black is more suitable for fields that require transparency, dispersibility, and adsorption due to its high specific surface area and hydrophilicity; Carbon black, on the other hand, is widely used in the fields of rubber, coatings, and electronics due to its conductivity and black appearance. With the advancement of technology, the application scope of white carbon black continues to expand, especially in the context of increasing demand for green and high-performance materials.
