    Calcium Carbonate 99%: High-Purity Mineral for Industrial and Commercial Use

    Calcium Carbonate 99% is a high-purity, naturally occurring mineral compound with the chemical formula CaCO₃. It is widely recognized for its versatility, stability, and eco-friendliness, making it a valuable material across industries such as plastics, paints, paper, construction, agriculture, and pharmaceuticals. With a purity level of 99%, this grade of calcium carbonate is considered ideal for applications that demand consistency, whiteness, and minimal impurities.

    Sourced from natural limestone or marble deposits, Calcium Carbonate 99% is processed into powder or granules of various particle sizes to meet specific industrial requirements. Due to its chemical neutrality and low abrasiveness, it is especially preferred in formulations where performance and safety are critical.

    Key Applications of Calcium Carbonate 99%

    1. Plastic and Polymer Industry

    Calcium carbonate acts as a filler and reinforcing agent in plastic products like PVC pipes, cables, and injection-molded parts. It enhances strength, durability, and surface finish.

    2. Paints and Coatings

    Used as an extender and pigment, it improves paint brightness, consistency, and opacity while reducing production costs.

    3. Paper Manufacturing

    Calcium carbonate improves the whiteness, printability, and bulk of paper. It replaces kaolin in many coated and uncoated paper types.

    4. Construction Materials

    In the construction sector, it is used in cements, adhesives, sealants, and tiles as a mineral filler to enhance compressive strength and workability.

    5. Agriculture

    Calcium carbonate is used as an agricultural lime to neutralize acidic soils and supply essential calcium for plant nutrition.

    6. Pharmaceutical and Food Grade Use

    With proper certifications, high-purity calcium carbonate is used as a dietary calcium supplement, antacid, and a food additive (E170).

    Benefits of Using Calcium Carbonate 99%

    • ✅ High purity (99%) ensures consistent performance

    • ✅ Brilliant whiteness for superior aesthetics in paints and plastics

    • ✅ Cost-effective filler that reduces production costs
