Detailed Description

Nanometer silicon dioxide Nanometer silicon dioxide(Nm-SiO2) is a new kind of inorganic materials, because of its extra small size. It has many special characteristics,such as big surface volume, quanta tunnel, and so on. Product name: Nanometer silicon dioxide CAS No.: 14808-60-7 Synonyms: Nanometer silica Formula: SiO2 Chemical structure: O==SI==O Mol. Wt.: 60.08 Specification: Item No. Particle size Density Assay Hydroxyl Percent UV reflectivity (nm) (g/cm3) (%) (%) (%) VK-SP50 50±5 0.12 max 99.5 min 45 min 85 min VK-SP30 30±5 0.12 max 99.5 min 45 min 85 min VK-SP15 15±5 0.12 max 99.5 min 45 min 85 min Application: 1. Rubber: Nm-SiO2 can be used in re-attrite rubber for it can improve the functions of rubber such as intensity, tenacity, anti-aging, re-attrite and so on. It also can be used in transparent pastern of sole. 2. Plastic: Nm-SiO2 can improved the intensity, tenacity and anti-aging capabilities of plastic. Adding nm-SiO2 into organic glass (PMMA) can improve PMMA's intensity, impactive tenacity, attrited resistance, transparence, anti-ultraviolet and anti-aging capabilities. 3. Epoxy resin :Its rigidity, intensity, tenacity, high temperature resistance and anti-aging capabilities can be improved after being modified by nm-SiO2. 4. Coating: Using nm-SiO2 in coating can improve its suspend stability, thixotropic, weatherability, anti-washing and anti-infra-red. 5. Gooey and sealant: Adding nm-SiO2 into gooey or sealant can improve the ropy of gooey and the sealed ability of sealant. 6. Other industries It can be also used in electronic encapsulation, polymer of macromolecule, paint, adhesive, functional fiber, cosmetics and many more applications. Packing: 5kgs/bag
