Silica Powder

Product Description

Hello Good day. Our Crystalline silica powder made of white natural silica stone, is through selecting, purity water treating, grinding, drying and sieving. For its high content, pure with color, stable physical and chemical properties and reasonable controllable partical size distribution it is widely used as material for epoxy potting compound, epoxy molding compound of electronic and electrical industries and engineering plastics, silicon rubber, precision casting, ceramic, refractory, artificial marble, paint and ink industries etc. We also can supply active silica powder of every specification which sink time does not less *5 minutes.
