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 doesnt 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 UL94VO.4. Functions This products belong to non-halogen, smokeless, have no leaked, no toxicity retardant. It is the ideal retardant material on rubber, plastic rubbers, electric apparatus, engineering plastic etc. And it can be widely used in PP. PE. PS. PC. ABS. EVA. PVC, EPDM etc. It also can be used in such kinds of engineering plastic as PBT, PA under the conditions of high temperature and simultaneously used with many other kinds of retardants, thus make the products have very good retardant performance of smoke elimination. In product of application, it is suitable for wires, cables, electric apparatus, building material, glass fiber, and so on. Provided using 50% magnesium hydroxide instead of hydrogen alumina in the PVC and rubber, it would obviously improve the function of restraining smoke and the rate of oxygen.
