Product Overview
Kulubrite 10 is a floated, high-brightness calcium carbonate powder designed for use as a filler, extender and functional mineral raw material across industrial manufacturing.
Compared with Kulubrite 5, the larger approximately 10 µm median particle size makes Kulubrite 10 suitable for formulations where economical filler loading, controlled texture and good processing characteristics are required.
