Precipitated silica is mainly used as rubber strengthening agent and additives. It can be used to manufacture white, transparent rubber products, also widely used in the industries of plastic, Paint, ink, Paper, Pharmaceutical, Daily chemicals and food because of its non-toxicity and smelless.

We have many type about this porduct, such as 336,356,178,601,178K,356GJ, etc; also powder or sheet form is all.
