Ball silica powder
I. Characteristics and application:
The ball silica powder of our company is made of a kind of quality natural powder quartz development by us by special processing with SiO2 up to 98-99.5%, Fe2O3 < 0.02%, whiteness degree of 90-95%, and natural grain size of 325-1000 mesh. The quasi-ball microcrystal quartz grains are found under the microscope.
Such powder quartz after the special treatment has the excellent fluidity without any radioactive material. It can be broadly applied in sealing plastic for integrated circuit, pouring resin, pouring sealant, silicon rubber and painting, coating, plastic, fine casting, refractory material, glass fiber and artificial quartz.
