Supply silica (food grade)

The analysis accord HG2971-1996(standard heavy metal content) and sanitation request.

I. Application of water reducing

BT-40 series silicon dioxide additive are main used as water reducing , viscosity, stabilization of food, medicine and animal food and carrier, clarify assistance and the attach water reducing of essence and spicery. The appearance of the product is white powder. Because of the sub-micro size and large BET of silicon dioxide, it can act as interval material between the granules of powder, at the same time, it also can prove the free flow of powder. Its water reducing feature can promote sorption and to prevent exist nubby.

BT-401 belongs to medicine grade, it is main used in medicine career.
