Specifications and Other Information of Our Silicon dioxide CAS 7631-86-9
Product features
Silicon dioxide has high purity, small particle size, uniform distribution, large specific surface area, high surface activity, high temperature resistance, and low bulk density ;
Silicon dioxide has good dispersibility, suspension, vibration liquefaction ; and good thixotropy, as well as good reinforcement and thickening effects ; after surface treatment, it has better hydrophilicity and lipophilicity ;
There are a large number of unsaturated residual bonds and hydroxyl groups in different bonding states on the surface. Due to the lack of oxygen on the surface, it deviates from the stable silicon-oxygen structure, so it has high reactivity, the powder has a relatively small bulk density, and is easy to disperse and use ; it has high reflectivity for both ultraviolet and visible light. The reflectivity of ultraviolet short waves (200~280nm) is 70%-80%; the reflectivity of ultraviolet medium and long waves (280~400nm) is 80%-85%; the reflectivity of visible light (400~800nm) is more than 85%; the reflectivity of near-infrared rays in the 800~1350 band is also more than 70%.

Known Application
Rubber modification, sealant ceramic toughening, adhesive modification, functional fiber additives, plastic modification, paint aging resistance additives ; ceramics, nano-ceramics, composite ceramic substrates ;
Polymers : can increase the thermal stability and aging resistance of polymers ;
Flame retardant materials, coatings, advanced grinding media, cosmetics and other products ;
Adding a small amount of nano-SiO2 to solution-polymerized butadiene styrene and chlorinated polyethylene to produce colored rubber products with toughness, strength, elongation, flexural resistance, and resistance to ultraviolet aging and heat aging, etc., all reach or exceed EPDM rubber ; adding a small amount of nano-silicon oxide to traditional coatings can solve the problems of poor suspension stability, poor thixotropy, poor aging resistance, and low finish.
