Applications

The Fused Silica Block is out of super fine and high quality natural silica ore by selecting and melting, processing, classifying and so on. This technology enabled the Sino Surplus International Limited the first mover as well as the leading producer and research institute in this industry. 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, appliances and epoxy resins and especial in the semi-conductor products of the IT field etc.　

Because of its special properties and excellent characteristics the Fused Silica Block 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 Fused 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, the micro fused silica powder applies to both large-scale components and small-scale precise electrical components.
