Plastics & PolymersFunction:Reduces material costs (20-40% loading in PVC/PP/PE).Enhances impact strength (nano CaCO3 for engineering plastics).Grades:Stearic acid-coated: For better polymer bonding.Nano CaCO3: For high-end composites. 2. Paints & CoatingsBenefits:Replaces 10-30% TiO2 (cost savings).Improves opacity & weather resistance.Recommended: 1250+ mesh for smooth finishes. 3. Rubber IndustryRole:Reinforcing filler in tires, hoses (10-30% loading).Silane-treated CaCO3 boosts tensile strength. 4. Construction MaterialsUses:Cement additive (5-15% for faster setting).Tile adhesive filler (improves workability). 5. Paper ManufacturingAdvantages:Coating pigment for high-gloss paper.Filler to reduce pulp usage. Usage Guidelines Dosage RecommendationsIndustryTypical LoadingNotesPlastics (PVC)20-40%Higher loading reduces costPaints10-30%Adjust based on TiO2 replacementRubber10-30%Use coated CaCO3 for better dispersionConstruction5-15%Mix dry with cement Critical Precautions Storage:Keep in dry, sealed containers (RH <60%) to prevent caking.Avoid contact with acids (releases CO2 gas). Handling:Wear dust masks (for fine powders) and goggles.Use anti-static equipment for bulk loading (dust explosion risk). Compatibility:Not suitable for acidic environments (pH <5).Test heat stability if used in plastics >200°C.
