Note: According to user requirements of particle can provide different size products.

Product performance:

1. There are a large number of unsaturated residual bonds and hydroxyl groups in different bonding states on the surface, which deviate from the stable silica structure due to the lack of oxygen on the surface, so it has high reactivity, low bulk density and easy to disperse.  

2. Nanoscale silica prepared by sol gel method in our company is prepared by sol-gel method. The particle size is small, uniform and controllable. In view of the different system of customer use, the company can carry out targeted surface treatment packages so that nano-sized silica powder can be dispersed in solvent system stably, forming transparent or semi transparent colloidal colloids. It is used in coatings, glass surface, electronic packaging, etc.

3. Both ultraviolet and visible light have high reflectivity, reflectivity of ultraviolet short wave (200-280 nm) is 70%-80%; reflectivity of ultraviolet medium-long wave (280-400 nm) is 80%-85%; reflectivity of visible light (400-800 nm) is more than 85%; reflectivity of near infrared line in 800-1350 band is more than 70%.

Application Fields:

1. Rubber modification, sealant ceramic toughening, binder modification, functional fiber additive, plastic modification, anti-aging additive for paint;
2. Ceramics, nano-ceramics and composite ceramic substrates;
3. Polymer: It can increase the thermal stability and aging resistance of polymer.
4. Flame retardant materials, coatings, advanced grinding media, cosmetics and other products;
5. The toughness, strength, elongation, flexural property, anti-ultraviolet aging and thermal aging properties of color rubber products produced by adding a small amount of nano-SiO_2 into solution-polymerized styrene-butadiene and chlorinated polyethylene reach or exceed those of EPDM.
6. The problems of poor suspension stability, thixotropy, aging resistance and low finish were solved by adding a small amount of nano-silica in traditional coatings.
7. Drug carrier, sustained-release microcapsules.
