Good quality brucite fiber
Brucite
1. Features
1) Brucite fiber a rare magnesium hydroxide fiber at home and abroad. |
2) It is white , easy to split and high velvet rate. |
3) Its unique and excellent performance and low price is the important element of replacing asbestos. |
4) It could be used in reinforcing materials and additives. |
5) It supplies a good opportunity for many enterprises which produce asbestos, cement, rubber, brake, friction, sealing, thermal insulation, paint, textile, absorbent, flame retardants. |
6) The use of fiber brucite will enable your product to become non-asbestos products, meet with requirements of domestic and foreign customers. |
7) Brucite fiber will give your business with a new vitality. |

6.Main Features and Application of Brucite
1)The chemical composition of brucite fiber is different from other asbestos. Physical property is similar to asbestos. It is the ideal material to replace asbestos. The last two years, many enterprises produce successfully qualified non-asbestos products in friction and sealing industry. They have declared the patent. In asbestos-cement products,it has successfully replaced asbestos completely and partly. |
2)Brucite fiber is hollow fiber. It has high melting point. It plays an important role in high-temperature areas.Especially it has a unique use in the production of microporous calcium silicate. It is preferred raw material in insulating materials ,such as section material, powder, paste. |
3)Brucite fiber is a natural, inorganic and flame retardant materials.It not only has greater economic advantages than magnesium hydroxide extracted from the water, but also has better use features than organic flame retardant. In this areas, the prospects are very broad.. |
