Q1: What is the primary function of Imerys 2500C Pigment in polymer systems?
A: Imerys 2500C Pigment is a high-purity, surface-treated calcium carbonate designed primarily to provide opacity, brightness, and controlled rheology in thermoplastic and thermoset compounds—particularly where consistent dispersion and minimal impact on mechanical properties are required.
Q2: Is Imerys 2500C Pigment suitable for food-contact or medical-grade applications?
A: While Imerys 2500C Pigment meets general industrial purity specifications and is manufactured under strict quality controls, its suitability for regulated applications such as food contact or medical devices depends on final formulation validation and compliance with applicable regional regulatory frameworks. Customers should consult Imerys technical support and conduct appropriate testing for their specific end-use requirements.
Q3: How does Imerys 2500C Pigment differ from standard ground calcium carbonates?
A: Unlike conventional ground calcium carbonates, Imerys 2500C features a tailored surface treatment that enhances compatibility with non-polar polymers, improves dispersion stability, and reduces agglomeration during compounding—resulting in smoother melt flow and more uniform color development in pigmented systems.
Q4: What are typical processing considerations when incorporating Imerys 2500C Pigment into masterbatches?
A: For optimal performance, pre-drying is generally not required due to its low moisture sensitivity, but good mixing energy and sufficient residence time during extrusion are recommended to ensure complete deagglomeration and uniform distribution. Dosage typically ranges from 0.1% to 2% by weight depending on the desired opacity and base resin characteristics.
