Food grade Silicon Dioxide

 

Product Name

Silica,Precipitated Silica,Hydrated silica(SIO2)

Molccular Formular

SIO2.NH2O

Appreance

White crystals or poeder

Advantage

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.

Applications

1) Shoes-making industry: rubber outsole reinforcement agent similar to black

carbon. It brings the light color and transparent appearance of rubber outsole

with excellent performance

2) Tyre industry: decreases friction on ground sharply, and increases the tyre

holding on the wet and icy ground. The bonding between curtain threads or

woven material and rubber compound is improved

3) Silicon rubber: its aging, resilience and compression set are increased

4) Plastic industry: increases the plastic products' flexibility, strength and

resistance to water

5) Coating industry: it provides the performance in preventing coating from

aggregating and hanging down. It can increase the viscosity and dull the

coating shine

6) Pharmaceutical industry: it gives a function of increasing the viscosity, floating

and dispersing. It can be a carrier and an anti-lumping agent
