PCC

Precipitated Calcium Carbonate

An Introduction to Precipitated Calcium Carbonate (PCC)

Precipitated Calcium Carbonate (PCC) is an exquisitely refined, synthetic variant of calcium carbonate, crafted through a meticulously controlled reaction between calcium hydroxide and carbon dioxide. This process affords unparalleled precision in regulating particle size and morphology, yielding a product distinguished by its exceptional purity and uniformity.
At Yamuna Calcium, our PCC emerges from an exacting synthesis, producing ultra fine calcium carbonate particles of remarkable clarity and consistency. This makes it an exemplary choice for industries demanding superior brightness and opacity, such as paper manufacturing, plastics production, and paint formulation.

Key Properties & Advantages of PCC
Exceptional Brightness: Imparts striking whiteness and enhanced opacity to finished products, rendering it indispensable for the paper and paint sectors.
Precisely Engineered Particle Size: Facilitates a flawless surface finish and lustrous gloss, elevating the quality of applications in plastics and coatings.

Uncompromising Purity: Devoid of contaminants, it guarantees optimal efficacy in delicate applications, including pharmaceuticals and food-grade formulations.
