Active Silica micropowder is a kind of non-toxic, tasteless, pollution-free, hydrophobic and lipophilic high-purity white silica powder. It is an effective high-temperature modified coating treatment on the surface of silicon powder particles with coupling agent, which improves the mechanical, electronic and chemical characteristics of the mixture and the filling system. It has good temperature resistance, acid and alkali corrosion resistance, poor thermal conductivity, high insulation, low expansion, chemical stability, high hardness and other excellent properties. The fluidity of the powder in the resin is enhanced, so that the products can obtain better impact strength, rigidity, cold and heat resistance and other physical properties.
Application scope: widely used in the pouring of high-voltage electrical appliances (such as dry-type transformer); rubber and plastic functional filler; artificial stone main material; building structure rubber filler; epoxy resin pouring filler; electrical insulation filler; used in rubber products can improve the wear resistance, high temperature resistance, weather resistance, increase mechanical properties, and extend the service life of products. It is the insulating filler of various potting materials, castables, encapsulating materials and plastic sealing materials in the field of electronics and electrical appliances, as well as the filler of paint, rubber and plastic products.
1. Improve the fluidity and affinity of silica powder in polymer and organic solvent such as resin.
2. Improve the wear resistance, weather resistance, high temperature resistance of products, increase the impact strength and mechanical properties of materials, and extend the service life of products.
3. Greatly improve the filling rate of silica powder and greatly reduce the cost of raw materials.
4. Enhance the dispersion in organic matter and improve the fluidity of products.
Main specifications: 400 mesh, 600 mesh, 800 mesh, 1000 mesh, 1250 mesh, etc.
