SPW 25N is a premium-grade, uncoated calcium carbonate powder manufactured by PT. Supersonic Chemical Industry from high-purity, superwhite limestone. Engineered for exceptional dispersion and optical performance, it features a median particle size (D50) of 6.4 ± 0.3 µm and top cut (D98) of 36 ± 4 µm. With ≥99.46% CaCO₃ purity, ≤0.25% moisture, and brightness ≥90%, SPW 25N enhances opacity, durability, and cost-efficiency in paints, plastics, rubber, ceramics, and paper applications. Its low oil absorption (≤14 g/100g) and ISO-certified testing ensure consistent quality and compatibility across industrial formulations.
