Lihat Profil SellerUltra-fine, ultra-white calcium carbonate with D50 of 3.0 μm for high-performance paints, plastics, and paper
SWR 8N is a premium-grade calcium carbonate powder manufactured by HighT using state-of-the-art technology from select limestone deposits. Renowned for its exceptional purity, ultra-fine particle size (D50: 3.0 ± 0.2 μm), and brilliant whiteness (brightness ≥92.00%), SWR 8N delivers consistent performance across demanding industrial applications. With minimal moisture content (≤0.25%) and extremely low impurity levels (Al₂O₃ < 0.01%, SiO₂ = 0.01%), this powder ensures superior dispersion, enhanced aesthetic quality, and long-term stability in end products. Ideal for industries requiring high brightness, smooth finishes, and reliable filler performance.
