Nano calcium carbonate

Main Uses
Nano Calcium Carbonate ManufacturerUsed in plastics, it has good affinity with resins and can effectively increase or adjust material rigidity, toughness, and flexural strength, among other properties. It also improves the rheological properties of the plastic processing system, reduces plasticization temperature, and enhances the dimensional stability, heat resistance, and surface finish of the final product. In rubber systems such as natural rubber, polybutadiene rubber, and styrene-butadiene rubber, it is easy to mix and disperse evenly, making the rubber compound softer. It also improves extrusion processing performance and mold flowability. The resulting rubber products exhibit characteristics such as a smooth surface, high elongation, high tensile strength, low deformation, good flexural resistance, and high tear strength.
Due to its high gloss, low abrasion rate, surface modification, and oleophobic properties, nano-calcium carbonate can be used as a filler in polymers such as polyvinyl chloride (PVC), polypropylene (PP), and phenolic plastics. It is now widely applied in the production of PVC profiles, pipes, wires and cables' outer sheath granules, films (calendered films), and footwear manufacturing. It is also suitable for modifying plastics such as polypropylene (PP), polyethylene (PE), and polycarbonate (PC). Because activated nano-calcium carbonate has an oleophilic and hydrophobic surface, it exhibits good compatibility with resins, effectively improving or adjusting the rigidity, toughness, gloss, and flexural strength of products. It enhances processing performance, improves the rheological properties, dimensional stability, and heat resistance of products, and provides filling, reinforcing, and toughening effects. It can replace some expensive fillers and additives, reduce the amount of resin used, thereby lowering production costs and improving market competitiveness.
Nano Calcium Carbonate ManufacturerIn the coating industry, it can be used as a pigment filler, offering advantages such as fineness, uniformity, high whiteness, and good optical performance. Nano calcium carbonate exhibits a steric hindrance effect, which, in paint manufacturing, helps suspend lithopone with higher formulation density, preventing sedimentation. After paint production, the whiteness of the paint film increases, gloss is enhanced, while the hiding power does not decrease. This characteristic has led to its widespread application and promotion in the coating industry.
Raw materials that can be used for coated processing paper, particularly forCoated paper. Due to its good dispersion performance and low viscosity, it can effectively improve the whiteness and opacity of paper, enhance smoothness and softness, improve ink absorption performance, and increase retention rate.
As a filler, it can replace the more expensive colloidal calcium, enhancing the gloss and brightness of ink. Nano calcium carbonate is also used in the feed industry as a calcium supplement to increase the calcium content of feed, and in cosmetics, it can replace titanium dioxide.
