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.
Mainly hydrophilic silica under appropriate conditions react with the silane coupling agent from the system for a surface with polysiloxane grafted solid powder silica, the hydrophobic contact angle up to 70 -150, not only has good hydrophobicity, as well as anti-foaming function.
Applications:
Applied to the textile dyeing and finishing, defoamers, lubricants, unsaturated polyester resins, powder fire extinguishers, and silicone rubber products.
Superfine white carbon black, silica, ultrafine silica price of superfine white carbon black manufacturers, nano-silica
