Precipitated Silica IOTA FINE SIL7365 

 

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.

Silica for high transparent and reinforcing silicone rubber

IOTA FINE-SIL7365 has more reinforcing effect than ordinary precipitated silica in rubber industry, especially in the silicone rubber industry, it can provide not only good tensile strength and wear resistance but also provide good color, good transparency, good appearance, not whitening after stretching and no deformation.

 

Silica for carrier and filler

IOTA FINE-SIL7365 can be done with low impurity treatment, then they will have high specific surface area, can be used as carriers in feed additives, pesticides, laundry powder and other industries to increase their fluidity, and can be colored in ceramic glazes. The effect of solid color is good and it will not discolored by long term high temperature condition.
