What is the future investment potential of the flame retardant magnesium hydroxide market? Flame retardant magnesium hydroxide industry developed earlier, the market is mature and stable. The flame retardant industry in Asia started late, but with the rapid development of China and India’s economy, driving the rapid growth of the flame retardant industry, has become the world’s largest flame retardant consumer market. Magnesium hydroxide is an important magnesium chemical product, as a kind of alkali agent with strong buffer performance and high efficient chemical adsorption performance, it has a wide range of applications in the fields of environmental protection, ceramic materials, medicine and so on. In recent years, and because of its high decomposition temperature, high thermal stability, non-toxic, non-smoke and smoke suppression and other characteristics, in the field of inorganic flame retardants have been developed faster.
Magnesium hydroxide is a new type of filler-type flame retardant, through the thermal decomposition of the release of bound water, absorbing a large amount of latent heat, to reduce the surface temperature of the synthetic materials it fills in the flame, with the inhibition of the decomposition of polymers and the resulting combustible gases for the role of cooling.
China’s magnesium hydroxide production of raw materials are mainly water magnesite, light burning powder, brine and water chloride magnesite and so on. Liaoning mainly magnesite as raw material, the use of mechanical crushing and ultrafine crushing process to produce magnesium hydroxide products; Liaoning, Shandong, Hebei and other places to use light burnt powder direct hydration method to obtain heavy magnesium hydroxide; Hebei, Shandong, Jiangsu and Zhejiang coastal areas using brine synthesis of magnesium hydroxide; Shanxi, Qinghai and other places in the saline brine, magnesium chloride as raw material to synthesize the system to obtain magnesium hydroxide.
China formulated the industrial standard (HG/T3607-2000) for industrial powdered magnesium hydroxide, which was implemented on December 1 of the same year. This is the only professional standard seen so far. Foreign different specifications and varieties of magnesium hydroxide production scale is very large, in different areas of the application of nearly 20 years of history, but has not been seen by any official proposed standards issued. Therefore, the proposal of our industry standard is very pioneering. Flame retardant magnesium hydroxide industry share At present, foreign flame retardant magnesium hydroxide are mainly inorganic system, of which inorganic flame retardants in Europe and the United States accounted for more than 55% of the market share, and mainly aluminum hydroxide, magnesium hydroxide. China’s production and consumption of flame retardant varieties to organic flame retardants, inorganic flame retardant production and consumption ratio is still relatively low. More than 80% of domestic flame retardants are halogen flame retardants.
The global annual consumption of flame retardant magnesium hydroxide is more than 2.25 million t. Aluminum hydroxide is the most used flame retardant, accounting for 38% of the share. This is followed by halogenated flame retardant systems containing brominated and chlorinated products, which are usually used together with the synergist antimony trioxide, totaling 31%. Flame retardant magnesium hydroxide and other flame retardants such as inorganic phosphorus compounds, nitrogen and zinc based flame retardants account for the remaining 31%. Among the applications within the flame retardant magnesium hydroxide industry, sales of flame retardants used in construction applications will see the strongest growth. The construction market, in turn, will account for the largest share of global flame retardant demand at around 28%.
In 2021, global magnesium hydroxide consumption of the largest application consumption field is environmental protection (industrial wastewater treatment and industrial flue gas desulphurization, etc.), accounting for 45.0% of the total consumption; flame retardant applications accounted for 28.5%, other industrial applications accounted for 26.5%. Used as a flame retardant is the fastest growing area of magnesium hydroxide usage. In addition in the pulp and paper industry, magnesium hydroxide as a substitute neutralizer and cellulose protection agent is used more and more, 2022-2027 will also promote the growth of magnesium hydroxide.
At present, the domestic use of aluminum hydroxide is higher, but with the increase in polymer processing temperature, aluminum hydroxide is easy to decompose, reducing the flame retardant effect, the flame retardant magnesium hydroxide industry developed earlier, the market is mature and stable. Asian flame retardant industry started late, but with the rapid development of China and India’s economy, driven by the rapid growth of the flame retardant industry, has become the world’s largest flame retardant consumer market.
Nano magnesium hydroxide: nano magnesium hydroxide molecular formula Mg(OH)2, relative molecular mass 58.30, white fine powder, non-toxic, odorless, non-corrosive, relative density 2.36, refractive index 1.561, decomposition at 350 ℃; 430 ℃ decomposition is rapid; 490 ℃ decomposition of all. Soluble in strong acid solution and ammonium salt solution, insoluble in water. Flaky crystal, with typical nano-flake layered structure, decompose at 340℃ and generate magnesium oxide. Insoluble in water, soluble in acid and ammonium salt solution. The product has excellent properties such as high purity, small particle size, in-situ coating modification, etc. It can be dispersed more uniformly in PA, PP, ABS, PVC and other rubber and plastic products, and is widely used in rubber-plastic elastomers, high-grade cable materials, household appliances and other high-end products.
In the case of almost does not affect the use of strength significantly improve the material’s flame retardant, smoke suppression, drip and other properties, but also according to customer needs, in the nano-magnesium hydroxide generation at the same time using appropriate in-situ modification methods, for the special flame retardant magnesium hydroxide. Nano magnesium hydroxide by virtue of its unique dispersion, will be in the military, aerospace and other industries with the amount of significant growth, the next five years in Central Asia Pacific and the Middle East and other regions of the demand for this product will be increasingly large.
China’s economy and society in the sustained rapid development, industrial technology and other aspects of the gap between developed countries is getting smaller and smaller, there are enough reasons to think that China’s nano-magnesium hydroxide industry will catch up and catch up with the world’s developed countries. Magnesium hydroxide industry is known as the sunrise industry of sustainable development, with the Asian demand and industrial production level, the center of the world magnesium hydroxide market is shifting, China has become the fastest growing region of magnesium hydroxide market demand. Magnesium hydroxide is mainly used as filler in flame retardant, plastics, rubber, coatings, sealants and other industries. In recent years, with the rapid development of these industries, the demand for magnesium hydroxide is also increasing further, and the flame retardant, plastics industry will play a leading role in the growth of demand for magnesium hydroxide.
