Carbon black is divided into many kinds, such as pigment carbon black, special carbon black, white carbon black and so on. White carbon black is a kind of special carbon black with white color and soft texture, which is widely used in many fields.

Silica can be used as reinforcing agent of rubber, and its reinforcing performance is even better than that of pigment carbon black after superfine treatment. It is more suitable for making light colored rubber.

Silica can also be used as thickener, which plays an important role in the blending of oils and paints. At the same time, it can also be used as a paint fading agent, a thixotropic agent for electronic component packaging materials, a precipitant for phosphor when the screen is coated, a filler for color printing plate, and a mold release agent for casting.

The moisture-proof and insulation properties of the resin can be improved by adding silica into the resin. Filled in plastic products, can increase the skid resistance and oil resistance. Filled in the silicone resin, it can be made into plastics resistant to more than 200 ℃.

Silica is used as filler and surface ingredient in paper industry. It can also be used as pesticide carrier or dispersant, anti caking agent, liquid adsorbent and lubricant.

In general, silica is a kind of multifunctional carbon black, which can emit light and heat in different fields.
