Natural Heavy Calcium Carbonate
1.Product Introduction:
Natural heavy calcium carbonate selects natural,snow-white calcite as raw material, and processes through domestic advanced grinding equipment and foreign sorting equipment. Which is produced strictly according to ISO9001 Certificate of international quality management system, It is an all-purpose filler materials due to identical grain size, stable lustre, and excellent dispersion.
