Rubber industry: Calcium carbonate is used in rubber products. The higher the oil absorption value, the better the wettability and reinforcement of rubber
Plastic industry: Calcium carbonate is used in plastic products to reduce costs, improve stability, hardness, and stiffness, improve the processing performance of plastics, improve their heat resistance, improve their astigmatism, scratch resistance, smoothness, and toughening effect on notch impact strength, as well as the viscosity and flowability during mixing
Coating industry: Calcium carbonate added to coatings can serve as a high-quality filler for whitening, improving the glossiness of coatings and paints, while also playing a reinforcing role
Ink industry: Calcium carbonate is used in ink products, exhibiting excellent dispersibility, transparency, excellent gloss and covering power, as well as excellent ink absorption and dryness.
