- Dec 13, 2018-

There are many kinds of carbon black, such as pigment carbon black, special carbon black, white carbon black, etc. Among them, white carbon black is a special kind of carbon black, the color is white, the texture is soft, and it is widely used in many fields.


White carbon black can be used as a reinforcing agent for rubber. After super-fine treatment, the reinforcing performance is even better than that of pigment carbon black. It is more suitable for making light-colored rubber.


Silica can also be used as a thickener, which plays an important role in the blending of oils and lacquers. At the same time, it can also be used as a light-reducing agent for paints, a thixotropic agent for electronic component packaging materials, a precipitant for phosphors when fluorescent screen coating, a filler for color printing rubber sheets, a casting release agent, and the like.


When the white carbon black is added to the resin, the moisture resistance and insulation properties of the resin can be improved. Filled in plastic products, it can increase the slip resistance and oil resistance. Filled in silicone resin, it can be made into plastic with resistance above 200 °C.


Silica is used as a filler and paper surface ingredient in the paper industry. There are also carriers or dispersants for use as insecticides and pesticides, anti-caking agents, liquid adsorbents and lubricants, and the like.


In general, silica is a versatile type of carbon black that can be used in a variety of fields to produce heat.
