Product Description
Product Description
Aerosil 150 Fumed Silica (SiO2)
1. Introduction of Aerosil 150 Fumed Silica (SiO2)
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 150 Fumed Silica (SiO2): Mainly for acidic silicone rubber sealant, RTV silicone rubber (low water content), and neutral silicone rubber, and etc.
2. Main characteristics of Aerosil 150 Fumed Silica (SiO2)in physical and chemical aspects
High purity
Aggregated structure
Submicron particle size
Low bulk density
3. Applications of Aerosil 150 fumed silica
It can be applied as a thickening and thixotropic agent in silicone sealants, and used as a reinforcing filler in elastomers, mainly silicone elastomers.
4. Packing and Storage of Aerosil 150 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.
