Ground calcium
carbonate
Ground calcium carbonate products can be widely
used for paper making, plastics, PVC tubular products,
chemicals, rubber, coatings, paints and pharmaceutical
industries. Jinxiang ground calcium carbonate features
high whiteness, high purity, stable chemical property,
smooth surface and uniform granularity.
