CaCO₃
Premium Calcium Carbonate
Mined and milled in-house — calcium carbonate engineered for manufacturers who cannot compromise on consistency.
Overview
Mined and milled in-house — calcium carbonate engineered for manufacturers who cannot compromise on consistency.
Our premium calcium carbonate is mined from carefully selected mineral stock and milled in-house to tight particle-size tolerances, then quality-tested batch by batch before it leaves the plant. It is the raw material at the heart of our own paints and plastics — and a dependable, high-brightness filler and functional additive that behaves predictably in paints, plastics, rubber, ceramics, paper and construction materials, reducing cost while protecting the performance of the finished product.
