Common Silica Powder
Silica powder series products are formed by carrying out beneficiation, crushing, acid pickling, grinding, deionized pure water treatment, drying, high-temperature smelting and ultrafine grinding on high-purity quartz ore resources. Silica powder is divided into common silica powder products, high-whiteness high-purity silica powder products, fused silica powder products and active silica powder products (formed by coupling agent modification according to customer requirements) according to the differences of purity and processing modes. Silica powder is main applied to the fields of unsaturated resin, epoxy resin, epoxy resin castables, potting compounds, molding compounds, coatings, adhesives, silicone rubber, electronics, electricians, etc.
