CALCIUM CARBONATE

We stock calcium carbonates of different particles sizes which are very pure and very white. The ASCOM carbonates are some of the whitest in the world and are widely used for paint, paper, plastics and other uses.

Our coated calcium carbonate is well known to offer processing advantages in master-batch and PVC applications.
