SURFACE-MODIFIED ACTIVE MINERALS
Coated Calcium Carbonate Powder (CaCO3)
Ultra-fine active ground calcium carbonate surface-treated with high-purity Stearic Acid for superior polymer compatibility, high loading, and dispersion.
HIGH PERFORMANCE HYDROPHOBIC ACTIVE FILLER
Viet Lao Stone produces premium coated calcium carbonate powder processed from self-owned high-purity limestone quarries in Laos. Surface-treated with 1.0% – 1.2% stearic acid via continuous automated European coating systems, our powder achieves complete hydrophobic conversion (>= 98.0% activation rate).
The stearic acid coating significantly reduces compound viscosity, eliminates particle agglomeration, and improves mechanical tensile and impact strength in polymer compounding.
