Product Description
Product Description
Silicon Dioxide
1. Introduction of Aerosil SiO2 Silicon Dioxide
Hydrophilic fumed silica is manufactured by hydrolysing volatile chlorosilanes in an oxyhydrogen flame. The loose white powder consists of highly pure amorphous silicon dioxide. Hydrophilic silica is wetted by water and can be dispersed in water. Hydrophobic silica is produced by the chemical reaction of hydrophilic silica with reactive silanes. It has water-repellent properties and is no longer dispersible in water.
Aerosil SiO2 Silicon Dioxide: Mainly for HTV silicone rubber, ink, powder coating, PVC resin, unsaturated resin, thixotropy agent, cable insulation, gel, powdery and flaky pharmaceuticals, cosmetics and etc.
2. Main characteristics of Aerosil 200 Fumed Silica (SiO2)in physical and chemical aspects
High purity
Aggregated structure
Submicron particle size
Low bulk density
3. Applications of Aerosil SiO2 Silicon Dioxide
It can be applied as a thickening and thixotropic agent in many organic systems, e. G. In unsaturated polyesters, coatings, printing inks, adhesives, cosmetics and others. It is used as a reinforcing filler in elastomers, mainly silicone-elastomers, like HTV and RTV-2K. And act as a free flow additive in the production of technical powders, in food and feed and in pharmaceutical products.
4. Packing and Storage of Aerosil 200 fumed silica
Packing: Carton packaging, 10 kg/bag, and
Storage: Seal at low temperature, ventilated, dry place.
Shelf life: At least two years under normal storage conditions.
