The Refined Silica Powder, or Quartz Powder is out of super purified and high quality natural silica ore by applying special hi-tech methodology in the process of preliminary selecting, grinding, purifying, classifying and so on. This technology enabled the SinoSi the first mover as well as the leading producer and research institute in this industry. This product enjoys unmatched fineness, granularity, stability and know-how. The specific feature of free coarse granules and perfect chemical stability makes the super fine silica powder become the best filling materials and additive in comprehensive applications including paint-coatings, adhesive, sealants, silica gels and epoxy resins and etc.　

Because of its special properties and excellent characteristics the silica powder is widely used in areas of electronics, electrical apparatus, chemical industry, special micro motor, sealing of transistor and semi-conductor components, insulation casting of current transformer, voltage transformer, electronic transformer and dry-type transformer, epikote casting of high-tension cable connection, high-voltage insulator, high-voltage switch, insulation pipes and components of high-voltage electrical apparatus. The silica powder is also used in electric welding industry as protection coating. In addition, it acts well as epoxy powder coating and as the filling materials for arc resistant and weathering resistant surface painting. As the filling material for epikote, silica powder applies to both large-scale components and small-scale precise electrical components.

SinoSi’s Inspection is provided through Quality Control System(QCS) on production line by computer program, so SinoSi can guarantee the quality can be kept in a designed level.
