Hydrophilic Fumed Silica
Fumed silica, or pyrogenic silicon dioxide, is one kind of pure amorphous white inorganic powder that has a high specific surface area, nano-scale primary particle size, and a relatively high (among silica products) concentration of surface silanol groups. The properties of fumed silica can be chemically modified by reaction with these silanol groups.
Synonyms: Pyrogenic silica, Fumed Silica Dispersion, Silicon Dioxide, Fumed SiO2
Vapor phase 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, it 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.

1.Reinforcing: Improve the tensile strength, tear strength, toughness and impact resistance of the product;
2.Thickening, improving the product consistency of liquid system, rheological control, thickening without thinning;
3.Thixotropy, one touch change, improve the rheological and thixotropy of liquid systems;
4.Anti caking, promote and maintain the fluidity and anti caking performance of powder particles;5.Anti sagging: prevent the liquid from flowing and sagging, and improve the flatness of the construction surface;
6.Anti sedimentation improves the adhesion of various systems, effectively prevents layered sedimentation, and is an ideal suspending agent;
Thermal insulation: thermal conductivity and excellent thermal insulation effect;
Fumed silica is a very useful industrial chemical used in a variety of industrial and consumer products. Fumed silica poses a variety of health hazards to workers in various end-use industries and to those using products that use fumed silica.
1. in various resin additives, medicine, food and other fileds.
2. rubber, sealant, silica gel, adhesive, tile grout etc.
3. paint, coating, UPR,
4. CMP suspension etc;
5. Digital photo paper etc.
1.Paint and coating: as a hexagonal additive, it can effectively prevent pigment filler from settling and layering, improve the weather resistance, scratch resistance, sagging and leveling of the coating;
2.Ink, air silicon has good thickening and sedimentation performance, which can adjust the viscosity of ink and prevent pigment sedimentation.;
3.Resin, improve numerical thixotropy, make it have good tensile strength, bending resistance, milk, heat resistance and other properties;
4.Chemical fertilizer plays the role of adsorption, moisture absorption and anti caking in powder fertilizer and suspension and anti sedimentation in liquid fertilizer;
5.Silicone rubber, air silicon is a very ideal reinforcing agent for silicone rubber, which can greatly improve its tensile strength and tear strength.;
6.Adhesive sealant can be used as thickener and thixotropic agent to increase bonding strength and prevent sagging and collapse during fixed line operation;
7.Medicine: gas silicon can be used as anti caking agent, drug carrier and excipient of drugs, so as to prolong the efficacy;
8.Food: gas silicon in powder food can improve fluidity, prevent powder agglomeration and carrier adsorption;
9.Thermal insulation materials, gas silicon has low thermal conductivity, which makes it have base thermal conductivity and excellent
10.Toner: improve the fluidity, charge retention and environmental storage stability of toner, and improve the defects such as bottom ash and ghosting during printing;
11.Catalyst carrier: gas silicon has good adsorption, dispersion and high purity, which can effectively improve the catalyst effect. It is an excellent catalyst carrier;
