FQ-CACO3 is a high-quality calcium carbonate powder (CaCO₃) produced from naturally occurring limestone. Engineered to deliver superior whiteness and
consistency, this fine powder offers excellent chemical purity, low moisture, and
controlled particle size—making it suitable for a wide variety of industrial applications.
Applications
▪ Plastics & Masterbatch
Used as a key filler in plastic production to improve rigidity, reduce cost, and enhance surface finish in PE, PP, PVC, and other resins.
▪ Paints & Coatings
Improves opacity, gloss control, and rheological properties in interior and exterior paints, primers, and textured coatings.
▪ Paper Industry
Acts as a brightness and bulk enhancer in paper production, helping to reduce reliance on wood pulp.
▪ Construction Materials
Widely used in cement, dry mortar, wall putty, and tile adhesives for added strength, workability, and whiteness.
▪ Rubber Industry
Reinforces rubber products while enhancing processing and performance characteristics in tires, seals, and belts.
▪ Agriculture
Used as a liming agent and calcium supplement to balance soil pH and improve nutrient availability for crops.
