Magnesium Hydroxide Inorganic Flame Retardant Has Great Development Potential

The magnesium hydroxide belongs to additive type inorganic flame retardant. Compared with congeneric inorganic flame retardant, it has a better smoke suppressing effect. 80 percent of people died due to smoke in fire hazard, therefore, smoke suppression is more important than inflaming retarding in modern fire retardant technology.

During the process of production, use and abandon, magnesium hydroxide has no hazardous substance. What’s more, it can neutralize acid gas and acid gas produced by combustion process. So it is a environment friendly green flame retardant. The magnesium hydroxide has a high thermal decomposition temperature. It has 140? higher compared with common inorganic flame retardant aluminium hydroxide. The synthetic material with magnesium hydroxide can bear higher processing temperature. It is beneficial to accelerate the extrusion molding speed and shorten the molding time. At the same time, it is conducive to improve the flame retardance efficiency.

The magnesium hydroxide has small grain size, and is less wear on equipment. It is help for prolong life-span of processing equipment. Because of the low production cost, it can be widely used in polypropylene, polyethylene, polyvinyl chloride, high-impact polystyrene, ABS and other fields. At present, there are more than 20 enterprises to produce more than 20 varieties. The total annual production capacity is about 17 thousands tons. Now, a large number of countries is building or designing to build new equipment of magnesium hydroxide. According to the pertinent data, the total annual production capacity of magnesium hydroxide equipment is about 14 thousands tons in recent years.

At present, the domestic annual production capacity of magnesium hydrate fire retardant is about 13000 tons. Due to the increasing awareness of environmental protection, the foreign has used a large number of inorganic flame retardant. Among these, the inorganic flame retardant consumption quantity of America, Japan and Western Europe respectively accounts for 60%, 64% and 50%. And in the inorganic flame retardants, it centers on the aluminium hydroxide and the magnesium hydrate. Compared with aluminium hydroxide, the magnesium hydroxide has numbers of advantages. Therefore, the magnesium hydroxide occupies more and more proportion. Analysis of foreign statistical data, the magnesium hydroxide fire retardant consumption quantity of western developed countries occupy more than 30% of total measure of consumption. The American consumption is 50000 tons, the Western Europe is 80000 tons and the Japan is 30000 tons. The next 5 years, it anticipated that their average growth rate of the consumption will be about 12%, 8% and 7%. Based on the above analysis, the magnesium hydroxide fire retardant has a bright future.
