Powder Surface Modification Technology Trends

Powder Surface Modification Technology Trends

Powder surface modification technology trends and developments. Surface coating machines for GCC, talc, and kaolin to improve plastic, rubber, and coating performance.

Growing Demand for Coated Powder

Surface-modified mineral powders are gaining market share in the plastics, rubber, and coating industries. Coated GCC (stearic acid), modified talc (silane), and treated kaolin (polymer) offer improved dispersion, reduced moisture absorption, and enhanced mechanical properties in composite materials. LIMING's powder surface modification machine provides continuous coating with 95%+ activation degree.

Modification Technology Advances

Recent advances include: (1) continuous pin-mill coating for uniform stearic acid distribution; (2) plasma-assisted surface treatment for polymer grafting; (3) dual-coating systems combining hydrophobic and hydrophilic treatments for multi-functional powders. These technologies enable mineral powder producers to create differentiated, high-value products for specialized applications.
