Silica fume
Fumed silica is made by the hydrolyzed chlorosilane with high temperature in hydrogen and oxygen blaze. It is a kind of inorganic fine chemical products which is white, nonpoisonous, odourless and amorphous. HS972, HS974, and HS976 are hydrophobic fumed silica.
Hydrophobic fumed silica is produced by the chemical reaction of hydrophilic fumed silica and active silane (DMCS or HMDS). It presents hydrophobic property because its surface is replaced by the unhydrolyzed methyl groups. It is white powder with high purity and cannot be dispersed in water.
It is the combination of the chemical treament agent and the original hydrophilic oxide with chemical bond. Besides the advantages of hydrophilic products, hydrophobic fumed silica has low moisture absorption, great dispersion and rheological adjustment ability towards the polar system. Some products will be helpful to the R&D of new products by structural modifications based on a water repellent treatment. They can also improve the product performance in this way, e. G. In the liquid system, hydrophobic fumed silica can reach large addition amount with little effect on system.


Application
Rheology for the process.
Thickening for polar liquid, e. G. Epoxy resin.
Reinforcement for organosilicon elastomer.
Large volume of addition, e. G. Molded products.
Excellent Hydrophobicity to enhance anti-corrosion property.
Improvement of dielectric property, e. G. Cable compounds.
Flow agent for powder, e. G. Fire extinguishing agent.
Promotion of scratch resistance in coating and plastics
