silica

Compared with traditional power silica, our micro pearl production is environment friendly, has stronger appetency, biggish dispersiveability, upper diaphaneity, good mechanical capability. In general, It is widely used in rubber, shoes-making industry, like light-colored, color and high-grade transparent rubber products.
