Product Detail
White carbon black Precipitated silica white powder Molecular formula:SiO2nH2O Have rubber,tyre,sole,medicine,feed,food grade

  WHITE SILICA

Chemical name: Silica, precipitated, hydrated, White carbon black

Molecular formula: SiO2 · nH2O

Appearance: white granules or powder

Use:

It is widely used in the shoe making and tyre industry, besides these it may be used for the following aspects such as husk rice roller, spinning weaving roller, adhesive for paper making, pesticide carrier anti-coagulator for pesticides, viscose-increasing agent for toothpaste, additives for foodstuff and medicines, and anti-inflammation agent in hygiene and fire-proof materials.

Used for [medicine, feedstuff]: 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 transparency. 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.
