Brucite
1. Brucite is a rare fibrous magnesium hydroxide. Its chemical formula is Mg(OH)2.
2. Brucite is white colour and easy to split.
3. Brucite is ideal substitute for asbestos with excellent performance.
4. Brucite is used in producing rubber, braking, friction, seal, heat insulation materials, coating, textile, adsorbent, fire retardant etc. The finished product is asbestos-free.
