Anti-caking agent silicon dioxide is a white fluffy powder, the product can be solved by blocking the formation of moisture absorption under pressure, and with adsorption. Mainly added to particles, powdered food for preventing aggregation particles or agglomerated powdered food, or to maintain its free-flowing bulk material.
BT-40 series silicon dioxide is mainly used as food additives, pharmaceuticals and feed anti-caking agent, thickener, stabilizer and carrier, clarify adsorption desiccant additives, flavors and spices. Milky appearance uniform powder. Due to the large submicroscopic silica and large specific surface area, making it among the particles in the powder substance acts as a spacer, while promoting a free-flowing powder substance.
BT-401 is a pharmaceutical grade, mainly used in the pharmaceutical industry.
