Bao Lai’s Stearic acid-coated CaCO3 powder is produced from white marble (marble) originating from quarries formed in Yen Bai, Vietnam. Bao Lai marble has the characteristics of low impurities, crystals with uniform dispersion, high gloss, good hardness. The characteristics from the original materials along with the excellent machine chain system come from the leading countries in the field of supplying CaCo3 stone powder production lines
Typical application: Paint and plastic industry, paper industry…
