After surface modification treatment, enhance the compatibility with rubberand plastics, stable performances, better dispersion property, lower water absorption and oil absorption compared with ordinary aluminum hydroxide, which enable the stuffing to be increased in products, and reduce process viscosity, strengthen affinity, improve flameproof property, improve antioxidation and mechanical performance. They are used as ideal stuffing for plastic, rubber, artificial marble, and widely used in communication,[...]
