Product Name:

Silica

Molccular Formular:

SIO2.NH2O

Appreance:

Powder

Advantage of silica use for food additives:

1.Good fluidity

2.High porosity, strong absorbability                                                      

3.Mainly used as anti-caking agent                                                                

4.To be as carrier, is not easy to agglomerate,

excellent anti caking property, fluidity of the powder can enhance the liquidity of the production.
