Silica micro powder is a widely used inorganic non-metallic material with excellent dielectric properties, low thermal expansion coefficient, and high thermal conductivity. The series of silica micro powder products are processed from pure quartz powder through ultra-fine grinding technology. It features high brightness, fine particles, uniform particle size distribution, large specific surface area, and high purity. It is extensively used as a filler in coatings, paints, adhesives, silicone rubber, precision casting, ceramics, and epoxy resin potting compounds.
