Large calcium carbonate
Weighty calcium carbonate also named ground calcium carbonate, is developed by organic superior calcite, which has higher purity and whiteness. The dimensions ranges from unEPT400 mesh which is referred to as main merchandise, to 3000 mesh or previously mentioned, dependent on your necessity.
Hefty (Floor) Calcium Carbonate is commonly used as filler and improver in plastic, paint, paper-making, rubber, pharmacy, feed, daily chemical, ceramics, adhesives and ink industry.
