PRODUCTS
Main ingredients: Calcium carbonate, chemical formula CaCO3
Features:
Use high-quality limestone as raw material, with less impurities, uniform particle size, and low oil absorption. It is widely used in plastics, rubber, building material additives and other industries. Used in plastic composite materials, it can significantly improve the bonding strength and mechanical properties of the composite material interface; when used in various plastic pipes, profiles, plastic products, degradable plastics, and wire and cable materials, it can strengthen and strengthen. Improve gloss, improve quality, etc. Used in the rubber industry, it can improve the tensile, tensile, heat resistance, aging resistance, tear resistance and other properties of the product. Used in the coating industry, it can increase the thickness of the film, improve the wear resistance and weather resistance of the coating, and increase the powdering rate and spray area of the powder material.
