Product Description

Hydrophilic Fumed Silica

A.Characteristic:

It is a white and colloidal micro-particle with its primary micro-particle from 5-40 nm and has obvious properties such as thixotropy, reinforcing, thickening and filling etc. and is

insoluble in all kinds of solvents and liquids except hydrofluoric acid and concentrated bases.
