Precipitated Silica (White Carbon Black, Silicon Dioxide Nanopowder)

Product Overview

Precipitated silica, also called ‘white carbon black‘, is an amorphous form of silica (silicon dioxide, SiO2); it is a white, powdery material. Precipitated silica is produced by precipitation from a solution containing silicate salts.

Chemical Formula: SiO2
CAS Number: 10279-57-9
EINECS Number: 238-878-4

Precipitated Silica2

Q702 of ANYWHERE POWDER is a powder material with optical function, transparency and ultra-fine, can be used in coating, ink, adhesive, silicone rubber, plastic, toothpaste and papermaking. Features include high transparency, good toughness, ultra-fine and even particle size, etc. It can improve the transparency, tear resistance, adhesion, weather resistance and corrosion resistance of the material. Compared with other products of the same type, it has lower price and higher filling volume.
