Superfine Ultra White Nano Calium Carbonate CaCO3 for Rubber and Plastic Products¹

Product Description Product Description: Product name: Nano calcium carbonate   Specification: CCR-802Rubber and plastic specialized nanometer calcium carbonate CCR-800 has the following advantages:Ultra high whiteness:  up to 96.5% whiteness.1. Excellent flowability: During the plasticization process of PVC products, the flow performance is improved throughout the entire process, making the mixture easy to mix, and changing the processing performance, such as reducing product shrinkage, improving surface smoothness, and making the product more resistant to yellowing.2. Improving surface gloss performance: thanks to its good mixing with PVC, it can improve the surface gloss of the product. It has good tear resistance and low density in thin film PVC products.3. Excellent nanometer characteristics: because of its nanometer characteristics, its surface is active, and can decompose freely moving negatively charged electrons under sunlight and ultraviolet radiation, leaving positively charged holes. It has extremely strong activity, and is very easy to react with oxygen or organic substances, improving anti-aging performance.4. Mature application practice: It can be widely added to PVC soft products and hard plastic products, and through a large number of customer accumulation, it is a mature filling product.Packaging: 25kg/bag, inner PP bag and outer woven bag.Executive standard: GB/T 19590-2011Product Info Index NameStandard Calcium carbonate (dry base meter),% ≥95 Whiteness  ≥95MgCO3%  ≤2.5Specific surface area(m2/g)  ≥18Average particle size(nm)90-120moisture% ≤0.4Oil absorption ml/100g ≤36Crystal shape Cube,PrismHydrochloric acid insolube content%≤0.3PH value8-10.5Degree of activation% ≥99%
