What is hydrophobic white carbon and its parameter indicators

Hydrophobic silica is a porous amorphous silica with a white powder. Its primary particle size is nanoparticle. The final particle size is 2~3um. After blending with rubber, plastic and paint, it can make the product have A variety of good physical properties, it is a good filler for natural rubber and synthetic rubber light-colored products, on the one hand to reduce the amount of rubber, reduce costs, on the other hand can improve the hardness, wear resistance, reduce deformation, increase of rubber products Oil resistance; used in latex plastic leather, light material products, easy to release film and shape, reduce the weight of the product; used in wire and cable, can improve its insulation performance; used in paint ink, it is a good increase Thickener; used in coatings with excellent high temperature resistance, so this product is widely used in rubber, plastics, leather, paint, sports and cultural products.

Hydrophobic silica has a very high surface activity and is transparent and translucent in certain rubber products; it is especially suitable for light, bright, transparent and translucent rubber products. In addition, it can be used as a release agent for latex, an anti-settling agent for paints and inks, a thickener, a thixotropic agent, a mouth-opening agent for various plastic foil films, a pesticide granule, a dispersant, a binder material and a lightweight material product, and Toothpaste abrasives, etc., and can be used in medium and high-grade atomic ash series products.
