About Precipitated Calcium Carbonate
High Purity lime stone is calcined in Lime Kiln to produce quick lime which is slaked and further carbonated to produce PCC slurry, which is filtered and dried to produce pure white PCC Powder.
In paints, PCC is used as an anti-setting agent and in emulsion paints as a white opacity agent. In Printing Ink used as an extender to control strength and body of the ink. As a polishing agents in window and mirror cleaners.
PCC is used for paper coating, and as a filler in paper. It imparts better opacity, gloss, high brightness, surface finishing and improves printability.
Most importantly, it reduces the amount of wood fiber required to make paper, subsequently reducing the number of trees needed.
Also used as a filler in Leather Cloth, Wallpaper, Footwear, Shoes Compounding etc.
Precipitated Calcium Carbonate serves as a filler and extender in several sectors such as paper, plastics, paints, rubber, adhesives, and pharmaceuticals. Its smooth finish and high purity enable manufacturers to enhance product quality. Additionally, its used for pH adjustment, polishing, and as a dietary calcium supplement, making it an essential raw material in various processes.
Exceptional Physical and Chemical PropertiesWith an above 98% CaCO composition, PCC exhibits low moisture (max 0.2%) and a specific gravity of 2.72.9. Its microcrystalline powder form ensures a bright appearance and consistent performance, while the minerals low porosity and poor heat conductivity add to its stability in different manufacturing conditions. Its odorless, non-refractory, and maintains stability under ambient conditions.
Reliable Packaging and Shelf LifePCC is available in standard 25 kg or 50 kg bags, and customized packaging solutions are offered upon request. When stored properly in a cool, dry place, it remains stable for 1224 months, ensuring consistent supply and minimal waste for users. This reliable shelf life supports both ongoing production needs and extended storage requirements.
