Our precipitated calcium carbonate is produced through the precipiration method using high quality limestone as the raw material. It is widely used in such industries as the rubber industry, the oil painting industry, the plastic industry, the papermaking industry, the paint industry, the daily chemical industry and so on.
The superfine calcium carbonate has an excellent affinity. It can be used to improve the surface roughness, the flexure and the aging resistance of the produced goods as well as their filling amounts.
