Fumed Silica
Fumed Silica (fumed white carbon black) is one of the most important high-tech ultra-fine inorganic new materials. With CAS NO7631-86-9;white fluffy powder, non-toxic, tasteless and pollution-free.Because of its small particle size.
Fumed Silica has a large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion, thermal resistance, resistance and other aspects, has unique characteristics in many disciplines and fields with its superior stability, reinforcement, thickening and thixotropy, It plays an irreplaceable role.
Nano-silica, commonly known as “ultra-fine silica”, is widely used in various industries as an additive, catalyst carrier, petrochemical industry, decolorizing agent, matting agent, rubber reinforcing agent, plastic filler, ink thickener, metal soft polishing agent, insulation filler, advanced daily cosmetics filler and spraying materials, medicine, environmental protection and other fields. It also provides new material foundation and technical guarantee for the development of relevant industrial fields.

Fumed Silica: Guide
Silica is a general term for white powdered X-ray amorphous silicic acid and silicate products, mainly Precipitated Silica, Fumed Silica and ultrafine silica gels, but also powdered synthetic aluminum silicate and calcium silicate.1. Reinforcement: improve the tensile strength, tear strength, toughness and impact resistance of the product;
2. Thickening, improve the product consistency of the liquid system, rheology control, thickening without dilution;
3. Thixotropy, a touch of change, to improve the rheology and thixotropy of the liquid system;
4. Anti-caking, promote and maintain the fluidity of powder particles and anti-caking properties;
5. Anti-flowing and hanging: prevent liquid flow and hanging, improve the flatness of the construction surface;
6. Anti-settling: excellent thermal conductivity and heat preservation;
