Heavy Calcium Carbonate - Storaen (Cangzhou) International Trading Co.|Food Grade, Industrial Grade

Calcium carbonate, a naturally occurring mineral, has become an essential component in modern industrial and food applications. Heavy calcium carbonate—available in both high-fine white food-grade and industrial-grade forms—exemplifies this versatility. Derived from natural limestone or chalk through a meticulous grinding and classification process, this mineral powder plays a crucial role in numerous industries due to its unique properties and wide range of applications. This article explores the product's features, technical specifications, and real-world use cases, while highlighting the expertise of its manufacturer, Storaen (Cangzhou) International Trading Co..

Product Overview

Heavy calcium carbonate is a multifaceted material that serves as a critical filler in coatings, plastics, and other industrial applications. Its ability to enhance dimensional stability, hardness, and scratch resistance in coatings makes it a preferred choice for manufacturers. In the plastics industry, it increases stiffness, reduces shrinkage, and lowers production costs, offering a cost-effective solution without compromising quality. The pure calcium powder variant, with its fine particle size distribution, is particularly suited for high-filling applications where a smooth, uniform finish is required.

Key Features and Benefits

Heavy calcium carbonate's advantages stem from its physical and chemical properties. With a purity range of 95-99%, it ensures consistent performance across applications. Its white color and powder form make it ideal for products requiring a clean, uniform appearance. The industrial-grade formulation is particularly effective in reducing material costs while maintaining structural integrity. For food-grade applications, the product meets stringent safety standards, ensuring it is safe for use in food packaging and other related industries.

One of the standout features of heavy calcium carbonate is its ability to improve the mechanical properties of materials. In coatings, it enhances scratch resistance and dimensional stability, making surfaces more durable. In plastics, it increases stiffness and reduces shrinkage during cooling, which is critical for maintaining product quality. These benefits are further amplified by the product's fine particle size, which allows for better dispersion and integration into various matrices.
