A practical guide for coatings producers on using precipitated calcium carbonate (PCC): how it cuts cost, improves gloss and brightness, and which specs to check before buying.

Oil absorption value decides how much filler you can load into CaCO3 masterbatch. Here is what it means and why surface-modified PCC saves resin and cost.

Precipitated and ground calcium carbonate look similar on paper but behave very differently in PVC, masterbatch and coatings. Here is how to choose the right one for your plant.

When buying precipitated calcium carbonate (PCC), check CaCO3 content, whiteness, D97 fineness, oil absorption, moisture, pH and surface treatment. SHAOFEI TRADING explains the key specs every PVC, masterbatch and coating buyer should verify before ordering.

PVC pipe makers add precipitated calcium carbonate to cut resin cost, improve rigidity and surface finish. Here is what PCC does in PVC pipes and which specs to check when buying.
