Calcium carbonate occurs abundantly in several natural minerals. It can be crystallized in a wide variety of morphologies, which makes it very versatile and is, therefore, used for changing physical and chemical properties of filled or coated papers. The product of a controlled synthesis that produces a desired morphology and particle size is called precipitated calcium carbonate or PCC. PCC has a higher purity than natural or ground calcium carbonate (GCC).
Maximizing Efficiency and Performance with GCC/PCC
Calcium Carbonate is a foundational filler, but its true value is unlocked when optimized. Implementing these strategies helps manufacturers improve cost-efficiency while simultaneously boosting product performance characteristics:
- Choosing the Right Coating: How surface treatment (coated vs. uncoated) critically affects dispersion and compatibility in polymers and high-viscosity coatings, impacting final material strength.
- Smart Filler Replacement Ratio: Strategies for successfully substituting more expensive pigments (like Titanium Dioxide) with high-brightness Calcium Carbonate without sacrificing essential opacity or color properties.
- Improving Rheology in Paints: Utilizing ultrafine Ground Calcium Carbonate (GCC) to enhance viscosity control, leveling, and overall stability in high-solids coating formulations and sealants.
- Dispersion Technique Review: Actionable tips for reducing shear energy during compounding to achieve optimal particle separation and prevent the costly issue of particle aggregation.
- Minimizing Scrap Rates: Understanding how consistent material quality directly correlates with reduced processing variation, leading to higher output yields and significant reduction in industrial waste and scrap material.
Optimized material use is not just about cost reduction—it’s about gaining a competitive edge by achieving superior end-product characteristics with high-quality, dependable mineral input.
