Basic Information:
Name: Nano Silicon Dioxide nanopowder
CAS NO.: 7631-86-9
Molecular formula: SiO2
Molecular weight: 60.084
Characteristic: White powder
Assay: 99.9%
Product Description:
Silica (chemical formula: SiO2) is an acidic oxide, and the corresponding hydrate is silicic acid (H2SiO3). Silica is the most important compound of silicon. The natural silica present on the earth accounts for about 12% of the mass of the earth's crust. Its existence is crystalline and amorphous. It is collectively called silica.
Application Area:
1 Rubber modified, sealant ceramic toughening modification, adhesives, functional fiber additive, plastic modification, paint aging additives;
2 Ceramics, nano ceramic, composite ceramic substrate;
3 Polymer: can increase the thermal stability and anti-aging polymer;
4 Flame retardant materials and coatings, high grinding medium, cosmetic products;
5 In cluster butyl benzene and chlorinated polyethylene adding a small amount of nano SiO2produce color rubber tenacity, elongation, strength, flexural performance and ultraviolet resistance and thermal aging performance and achieve or exceed epdm;
6 In traditional coating adding a small amount of nano silicon oxides, good solve the suspension stability, thixotropy and poor, poor finish.

FAQ
Application Area:
Uridine 5-Mophosphate Disodium are produced through the hydrolytic reaction from Ribonucleic acid(RNA) as raw material by enzymatic catalysis to form four kinds of nucleotides 5- 'AMP (adenosine-5'-monophosphate), 5'-GMP•2Na(guanosine-5'-monophosphate, disodium salt), 5'-CMP(cytidine-5'-monophosphate)-, 5'-UMP•2Na (uridine- 5'-monophosphate,Disodium salt) .By the chromatographic isolation, four kinds of separated 5'-nucleotide products with high purity can be obtained. These products can be widely applied in medicine, reagent, fine chemical industry, and additive of food fields etc.
