Product Name: Silica, Precipitated Silica, Silicon Dioxide
Silica Powder Grade, a highly absorbent and fluid-enhancing agent suitable for applications like anti-caking and carrier functions in various industries. Silica Powder Grade offers excellent fluidity and strong absorbability, packaged for convenience in various sizes.
Molccular Formular: SiO2, NH2O
Appreance: Powder
Package: 15kg & 20kg PP woven bag, 25kg paper valve bag, 14.4kg EVA bag, 360kg/625kg big bag.
Advantage of Silica Powder Grade：
1. Good fluidity
2. High porosity, strong absorbability
3. Mainly used as anti-caking agent
4. To be used as carrier, is not easily agglomerated, excellent anti-caking property, fluidity of the powder can enhance
the liquidity of the production.
