Introduction

Ultrafine crystalline quartz silica powder  is a natural product , high purity(SiO₂  content of 99.5%) ,large surface area , high chemical purity , good dispersion , high whiteness , high brightness , low moisture content . It can be used in rubber , resins , coatings , paints , unsaturated polyester polymer materials as reinforcing filler materials . It is also known by its low expansion , good reinforcement , superior stability , products `physical strength , insulation properties , and can work with all kinds of other mixed powder filler without affect other powders ‘basic performance .

Application

Widely used i in rubber , plastics , unsaturated polyesters , paints , coatings and other polymer materials reinforced , modified ceramics , etc., but also for flat glass , foundry sand , glass fibers , ceramic color glaze , rust removal by sandblasting , sand filtration , flux , and the manufacture of lightweight refractory concrete bubbles .
