Silica micropowder is a widely used inorganic non-metallic material with excellent dielectric properties, low thermal expansion coefficient, and high thermal conductivity. The series of silica micropowders are produced through ultra-fine grinding of pure quartz powder. It boasts high brightness, fine particle size, 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.
