Precipitated Silica IOTA FINE SIL7325
IOTA FINE Precipitated Silica is a kind of superfine precipitated silicon dioxide (known as silica) made by special processing technology. It has excellent reinforcement and dispersion, many years of production practice shows that it can replace fully or partly of expensive fumed silica which has greatly reduce customers’ production cost.
