Fumed silica is one of the extremely important nano-scale inorganic raw materials. Because of its small particle size, it has large specific surface area, strong surface adsorption force, large surface energy, high chemical purity, good dispersion performance, thermal resistance, electrical resistance, etc. With specific properties, it has unique characteristics in many disciplines and fields with its superior stability, reinforcement, thickening and thixotropy, and plays an irreplaceable role. Widely used in various industries as additives, catalyst carriers, petrochemicals, decolorizers, matting agents, rubber reinforcing agents, plastic fillers, ink thickeners, metal soft polishing agents, insulating fillers, advanced daily cosmetics Filling and spraying materials, medicine, environmental protection and other fields. It also provides a new material foundation and technical guarantee for the development of related industrial fields. Because it shows special functions compared with conventional materials in terms of magnetism, catalysis, light absorption, thermal resistance and melting point, it has attracted great attention.

Fumed Silica - Product Characteristics
The product is an artificial synthetic amorphous white fluidity powder with strict particle size distribution of various specific surface areas and volumes. This product is a white, loose, amorphous, non-toxic, tasteless, odorless and non-polluting non-metallic oxide. Its primary particle size is between 7 and 80nm, and its specific surface area is generally greater than 100㎡/g. Due to its nano effect, it shows excellent properties such as reinforcement, thickening, thixotropy, insulation, extinction, and anti-sagging in materials. Therefore, it is widely used in polymer industries such as rubber, plastics, coatings, adhesives, and sealants.
As a liquid thixotropic agent and thickener, anti-sedimentation, anti-sag; improve the suspension and dispersion of pigment fillers in liquid systems; used as dispersion and grinding aids; improve coating corrosion resistance; improve powder fluidity , storage stability; improve powder charge and charge stability; improve water resistance; improve paint film scratch resistance; improve color brightness; fix special effects; improve paint film physical and mechanical properties; improve paint film adhesion and flexibility ;Improve the viscoelastic properties of rubber and elastomer, reinforce; defoaming effect in defoamer; improve coating surface hardness, anti-scratch; prevent adhesion in film and elastomer; as adsorbent and carrier; used for inkjet Printing coating; as advanced filling of dental materials; as catalyst carrier, remarkable thermal insulation, for low temperature and high temperature insulation.
