Nanometer Silicon Dioxide - China

price: contact company for price

Nanometer silica is one of the new super fine inorganic material is

extremely important in, because its particle size is very small, so the

large specific surface area, adsorption capacity, surface energy, due to

the specific properties of high chemical purity, good dispersion, heat

resistance, resistance and so on, with its superior stability,

reinforcement, thickening and thixotropy, unique properties in many

disciplines and fields, has an irreplaceable role. Nanometer silica,

commonly known as ' super fine white carbon black' , is widely used in

various industries as all kinds of packing materials, catalyst carrier,

bleaching agent, flatting agent, reinforcing agent of rubber, plastic

filling agent, ink thickening agent, metal soft polishing agent, a

thermal insulating filler, high daily use cosmetics packing and

petrochemical, spraying materials, medicine, environmental protection

and other fields. And for the development of related industry provides

new material basis and the technical guarantee. Because it compared to

show a specific functions in magnetic, catalyst, optical absorption,

heat resistance and melting points and I conventional materials, thus

gained much attention.
