Product introduction

Introduction and Application of CAS No.: 67762-90-7 / 68909-20-6 | Silanized Silica (SiO2)

Product features:

High purity, small particle size, uniform distribution, large specific surface area, high surface activity, high-temperature resistance, low packing density;

It has good dispersion, suspension, and vibration liquefaction.

It has good thixotropy and good reinforcing and thickening effects;

Better hydrophilic or lipophilic after surface treatment;

There are a large number of unsaturated residual bonds and hydroxyl groups in different bonding states on the surface, which deviate from the stable silicon-oxygen structure due to the surface oxygen deficiency, so it has a high reaction

Should be active, loose powder density is relatively small, easy to disperse use;

It is highly reflective to both ultraviolet and visible light. The reflectance of ultraviolet short wave (200~280nm) is 70%~80%. The reflectance of ultraviolet medium long wave (280~400nm) is 80%~85%. The reflectance of visible light (400-800nm) is more than 85%; The reflectance of near infrared rays in 800~1350 band is more than 70%.

Package, transportation and application of Silanized Silica

Package: 1kg (sample package), 2.5kg (Normal package)

Can be packaged according to customer requirements, please contact the salesman to negotiate.

Transportation: by courier/ by air/ by sea

Application:

Rubber modification, sealant ceramic toughening, binder modification, functional fiber additives, plastic modification, anti-paint aging additives;

Ceramic, nano-ceramic, composite ceramic substrate;

Polymer: can increase the thermal stability and aging resistance of the polymer;

Flame-retardant materials, coatings, advanced grinding media, cosmetics and other products;

The toughness, strength, elongation, folding property and anti-ultraviolet aging and thermal aging properties of the colored rubber products produced by adding a small amount of nano Si02 to dissolved styrene butadiene and chlorinated polyethylene reached or exceeded EPDM;

The problems of poor suspension stability, thixotropy, aging resistance and poor finish were solved by adding a small amount of nano silicon oxide into the traditional coating.

Storage precautions:

After receiving the goods, it should be sealed and stored in a dry and cool place, and should not be exposed to the air for a long time to prevent moisture agglomeration, otherwise, it will affect the dispersion performance and use effect.
