Product Description

Precipitated Silica White Carbon Black CAS NO. 10279-57-9

1.Description
his product improves the purity of silica, adopts the gel process, and optimizes the production equipment and production process, so that the product has a better particle size distribution, effectively improves the matting efficiency, and the transparency of the product is also greatly improved. improve. The refractive index of the matting powder is improved, making the refractive index of the powder and the resin closer, and it is also very easy to disperse under extremely unfavorable conditions, which is more conducive to the use of the matting agent to adjust the dullness. Special processing technology is adopted to make this product have good compatibility with various water-based resins, so as to achieve a good anti-settling effect.
A. Reinforcing: Improve the tensile strength, tear strength, toughness and impact resistance of the product;
B.Thickening, improving the product consistency of liquid system, rheological control, thickening without thinning;
C.Thixotropy, one touch change, improve the rheological and thixotropy of liquid systems;
D.Anti caking, promote and maintain the fluidity and anti caking performance of powder particles;
E.Anti sagging: prevent the liquid from flowing and sagging, and improve the flatness of the construction surface;
F.Anti sedimentation improves the adhesion of various systems, effectively prevents layered sedimentation, and is an ideal suspending agent;
G.Thermal insulation: thermal conductivity and excellent thermal insulation effect;

3. Application
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. 
A. in various resin additives, medicine, food and other fileds.
B. rubber, sealant, silica gel, adhesive, tile grout etc.
C. paint, coating, UPR,
D. CMP suspension etc;
E. 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).Thermal insulation materials, gas silicon has low thermal conductivity, which makes it have base thermal conductivity and excellent;
(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).Silicone rubber, air silicon is a very ideal reinforcing agent for silicone rubber, which can greatly improve its tensile strength and tear strength.;
(8).Food: gas silicon in powder food can improve fluidity, prevent powder agglomeration and carrier adsorption;
(9).Medicine: gas silicon can be used as anti caking agent, drug carrier and excipient of drugs, so as to prolong the efficacy;
(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;
(12).Optical fiber: gas silicon has excellent thickening thixotropy, which can effectively improve the filling efficiency of optical fiber filling paste;
