Industrial-grade calcium carbonate is known for its excellent chemical stability, low oil absorption, and good compatibility with polymers and resins. It has a high surface area, which contributes to improved mechanical properties in rubber and plastic products. Additionally, it exhibits excellent weather resistance and thermal stability, making it suitable for long-term outdoor applications. Its controlled particle size and uniform dispersion enhance the smoothness and durability of coatings, providing improved gloss and abrasion resistance.
