Brucite is a fibrous magnesium hydroxide rarely at home and abroad. It is white colour and easy to split.Nowadays brucite becomes ideal substitute for asbestos due to excellent performance and competitive price.Brucite is used as reinforcing material and additives. It also offers a good opportunity for for the domestic and international enterprises which produce asbestos, cement, rubber,braking,friction,seal, heat insulation materials,coating, textile, adsorbent, fire retardant etc.Brucite materials make your products be asbestos-free. It can meet the demands of Chinese and foreign customers.To research and develop new products with brucite injects new life into your enterprise.
