Product Description
Active silica powder is a kind of non-toxic, odorless, pollution-free hydrophobic (lipophilic) high purity white silica powder. We adopt special technology for customers of different industries and use different composite coupling agents to effectively modify and coat the surface of silica powder particles at high temperature, which improves the mechanical, electronic and chemical properties of the mixture and 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. Strengthen the fluidity of the powder in the resin, so that the product can obtain better impact strength, stiffness, improve cold and heat resistance and other physical properties.
Application
It is widely used in pouring high voltage electrical appliances (such as dry transformers),functional fillers of rubber and plastics, main materials of artificial stone, fillers of building structural adhesives, pouring fillers of epoxy resin, fillers of electrical insulation. The use of active silica powder in rubber products can improve the wear resistance, high temperature resistance, weather resistance, increase mechanical properties and prolong the service life of rubber products. It is the filling material for various potting materials, castables, sealing materials and plastic sealing materials in the field of electronics and electrical appliances, as well as filler in products such as paint and coatings, rubber and plastics.
