Silicon dioxide
White carbon black
Chemical name: Silica, precipitated, hydrated;
Molecular formula: SiO2 @ nH2O;
Appearance: White granules or powder
Use:

Used for [medicine, feedstuff]: Silica for medicine use is white granular powder with high purity, high fluidity, water absorption and flowage promotion, mainly used as auxiliary medicine materials and feedstuff additive.
Used for [silicon rubber]: For its special physical and chemical properties, it is the best transparent reinforcement additive in rubber-based blends. It can greatly improve the aging resistance, resilience and compressive deformation resistance of silicon rubber.

Used for [tyres]: If used in thread, it can greatly reduce the rolling resistance f tyres, and strengthen the holding power of types on wet or icy ground.

Used for [soles]: It is reinforcing filler for rubber soles with high reinforcing effect as that of carbon black, and it can make rubber products with light color or transmissivity.

Used for [food]: It is white fine powder with high purity, high fluidity and large specific surface area, mainly used as food anti-caking agent, antioxidant, thickener, coagulant, suspending agent, carrier of aromatical chemicals and active components, quality improver and oil absorber, etc.
