Calcium carbonate is a versatile and widely - used inorganic compound. It occurs naturally in forms such as limestone, marble, and chalk. In industrial production, it can be processed into different grades and particle sizes to meet diverse needs. With high chemical stability, it serves as an excellent filler in various industries. In the plastics industry, it can enhance the stiffness and dimensional stability of plastic products while reducing costs. In the paper industry, it improves the paper's smoothness, opacity, and printability. In the paint and coating sector, it contributes to better hiding power and durability. Additionally, in the field of construction, it is used in cement and concrete to enhance strength. Its wide availability and excellent performance make it a staple material in numerous applications.

Product function:
1. In the rubber industry, it can improve dispersion performance and product demolding performance, increase the surface smoothness and tortuosity of products, and also improve the processing performance and physical and mechanical properties of products.
2.In the use of the plastic industry, it can improve the flexibility, strength, and stability of plastic products, as well as improve the processing performance of the products, significantly increase the filling amount, and reduce mold wear. The tensile strength and impact strength of calcium carbonate filled in plastics and rubber after surface treatment are significantly higher than those of calcium carbonate filled systems without surface treatment, and shorten the kneading time during the processing process, improving production efficiency.
3.It can improve electrical insulation performance in cable products; Moderate pH, good compatibility with resin, and can increase the filling amount; Low cost, suitable for filling PVC wires and cables with paint.
4.It has better dispersion and stability in advanced inks, coatings, and varnishes, and can increase the glossiness, transparency, and rapid drying of products.
