SPC 10 CN is a superfine, stearic acid-coated calcium carbonate powder engineered for high-performance industrial applications. Sourced from superwhite limestone and processed with advanced technology, it delivers exceptional purity (≥99.46% CaCO₃), ultra-fine particle size (D50: 4.3µm), and superior dispersibility in polymer matrices. Ideal for plastics, rubber, paints, and masterbatches, it enhances mechanical strength, reduces formulation costs, and improves surface brightness and whiteness.
