Brucite Fiber

Brucite fibre (Mg (OH) 2), is a rare fibrous magnesium hydroxide at home and abroad stone, color white, easy to split and high easy splitting and high cashmere rate 

characteristics, its unique and excellent performance and low price, become the preferred natural substitute for asbestos today. As enhancement, reinforcing materials and additives, no asbestos cement, rubber, mainly used in brake, friction, sealing, thermal insulation, paint, textile, adsorbent, flame retardants and other products. Tensile strength: 892.4 to 1283.7 Mpa, moderate tensile strength and heat resistance: dehydration temperature is 400-500 ℃, melting point 1960 ℃
