SPC 25N is a high-purity, uncoated natural calcium carbonate powder derived from superwhite, high-grade limestone. Manufactured by PT. Supersonic Chemical Industry using advanced technology, it delivers consistent quality with a median particle size (D50) of 7.0 ± 0.5 µm and top cut (D98) of 36 ± 2 µm. Ideal for enhancing opacity, durability, and surface finish in paints, plastics, rubber, paper, glass, and porcelain applications. Its low moisture content (≤0.25%), high brightness (≥88.50%), and ultra-low impurities ensure superior performance and compatibility in demanding industrial formulations.
