Solution Description:
Ultrafine silica powEPTis a sort of inorganic non-metallic mineral purposeful powEPTmaterial, which is created from normal quartz ore and fused quartz by fine processing such as color separation, acid leaching, flotation, magnetic separation, grinding and precision classification. It has good particle dimensions, no huge particle, excellent suspension and slim particle dimension distribution. It has the traits of massive distinct area spot, excellent settlement resistance and specific reinforcing impact, as properly as superb houses of acid and alkali corrosion resistance, poor thermal conductivity, substantial insulation, minimal growth and higher purity.
Application: commonly employed in electronic resources, electrical insulation resources, paint coatings, ink, silicone rubber, combined silicone rubber, plastics (plastic film, plastic particles), practical rubber, sole rubber, chemical resources, nano-components, built-in circuit (IC) plastic sealing supplies and filling materials, precision casting, precision ceramics, adhesive, navy defense and other fields.
Major characteristics:
1. Wonderful particle dimensions, no big particles, high purity, great whiteness and uniform particle dimension distribution.
2, Reduced ion material, reduced conductivity, excellent electrical insulation.
three. Stable chemical properties, no response with any other substances besides hydrofluoric acid and strong foundation.
four, Very good suspension, good settlement resistance.
five, Acid and alkali resistance, higher temperature resistance, great insulation performance.
six,Large dress in resistance, increase the scratch resistance to coating.
