White carbon black has many unique properties, mainly used in rubber as a reinforcing agent, and its amount has accounted for 70% of the total amount. With the continuous development of white carbon black application fields, applications in the non-rubber field are being widely used. Abroad, non-rubber use has risen to a quarter of the total.

1.1.1 Application in rubber
The main purpose of white carbon black is to play a cross-linking role in rubber as a reinforcing agent. White carbon black is used as a filler for rubber. It is used to make shoe strips and transparent or opaque light-color soles. The rubber rollers and films and the tyre rubber compounds play the role of anti-ozone aging and ice grip.

1.1.2 Application in inks, paints and coatings
In inks, paints and coatings, white carbon black can be used as a thickener, thixotropic agent, dispersant, flow control agent and anti-settling agent. Vapor phase white carbon black is also used as a dispersant and flow control agent in the toner cartridge of copiers and laser printers. When the concentration is large and the diffusion performance is reduced, it can be used as a matting agent [2].

1.1.3 Application in Plastics
In the plastic industry, the addition of white carbon black can improve the strength and toughness of the material, and significantly improve the water resistance and aging resistance. White carbon black is added to polyvinyl chloride for the production of high-voltage wires; it is used in polyethylene plastic products to improve tension and wear resistance. Adding white carbon to various plastic films can change the surface properties of the film, making the film easy to open and not stick. In addition, white carbon black can also play a variety of properties in a variety of resins, polystyrene resin castings.

1.1.4 Application in other aspects
In addition to the application of white carbon black to the above fields, it can also be applied to the fields of medicine, pesticides, cosmetics, toothpaste, and paper. Activated white carbon has a large internal and external specific surface area, so it is an ideal carrier for medicine and pesticides; it can absorb a large amount of pesticides in pesticides; in the application of toothpaste, white carbon has good compatibility Physical properties, using white carbon as a toothpaste abrasive can clean teeth and remove spots; in the papermaking industry, it can increase the whiteness of paper and lighten paper quality, which is suitable for high-speed printing.

In short, as a functional additive, the application range of white carbon black will be more extensive, and its addition performance will be greatly improved [2].
