China factory high purity high quality low ion content good suspension white silica powder at best price

Product introduction: Silica powder is a kind of inorganic non-metallic mineral functional powder material, which is made of natural quartz ore and fused quartz by fine processing such as color separation, acid leaching, flotation, magnetic separation, grinding and precise classification. It has good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, high purity, high hardness and other excellent properties.

Application: Widely used in electronic materials, electrical insulating materials, adhesives, special ceramics, precision casting, paint coatings, ink, silicone rubber, functional rubber, liquid crystal glass, medical materials, dental materials, chemical materials, nano-materials, integrated circuit (IC) plastic sealing materials and filling materials, advanced construction materials, national defense and other fields.

Main features:

1. High purity, good whiteness and even particle size distribution.

2. Low ion content, low conductivity, excellent electrical insulation.

3. Stable chemical properties, no reaction with any other substances except hydrofluoric acid and strong alkali.

4. Low oil absorption, low viscosity, good dispersibility and fluidity.

5. Acid and alkali resistance, high temperature resistance, good insulation performance.

6.High wear resistance, improve the scratch resistance of the coating film.
