3. The characteristic of brucite and flame retardant 
3.1 By improving the surface of our product, it improves the compatibility 
with the high polymer material. Strengthen its strong function. In this way it can make good use of material and reduce the cost of the final products. 
3.2 This product doesn’t produce the poisonous gas while burning. Its hot stability is fine, resolve temperate is high which suits for processing in high temperature. 
3.3 Preventing from burning and good restrain smoke function, which can make the products up to the standard of UL—94VO. 

4. Functions
Brucite powders with or without coating belong to the class of  non-halogen, smokeless, no leaked, no toxicity fire retardant.
4.1 Brucite is ideally suited as a fire retardant for rubber and plastic in generl and in particular used by industries operating in the field of plastic coatings for all kind of electric apparatus. It is also widely used in PP. PE. PS. PC. ABS. EVA. PVC, EPDM and etc. 
It also can be used in such kinds of engineering plastic as PBT, PA in conditions of high temperature.
4.2 Bucite can be mixed with many other kinds of fire retardants to achieve finished products with very good retardant performance and  of smokeelimination. 
It is suitable for wires, cables, electric apparatus, building 
material, glass fiber, and so on. 
The use of 50% magnesium hydroxide in replacement of hydrogen alumina in the PVC and rubber, dramatically  improves the smoke elimination function  as well as the  rate of oxygen.
