Nano magnesium hydroxide: nano magnesium hydroxide molecular formula Mg(OH)2, relative molecular mass 58.30. white microfine powder, non-toxic, tasteless, non-corrosive, relative density 2.36. 350℃ start to decompose; decompose rapidly at 430℃; all decompose at 490℃. Soluble in strong acid solution and ammonium salt solution, insoluble in water. Flaky crystals, with typical nano-lamellar structure, decompose at 340℃ and produce 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 more uniformly dispersed in rubber and plastic products such as PA, PP, ABS, PVC, etc. It is widely used in high-end products such as rubber and plastic elastomers, high-grade cable materials and household appliances.
In the case of almost does not affect the use of strength significantly improve the material flame retardant, smoke suppression, anti-drip and other properties, but also according to customer needs, the nano magnesium hydroxide generation at the same time using appropriate in situ modification methods, for special flame retardant magnesium hydroxide. With its unique dispersion, nano magnesium hydroxide will gain significant growth in the amount of military, aerospace and other industries, and the demand for this product will grow in the next 5 years in regions such as Central Asia Pacific and Middle East, with an expected CAGR of 9% from 2020-2025.
The average growth rate of global flame retardant market size from 2017 to 2020 is 3.6%, and the global flame retardant market size is about 6.5 billion USD in 2017 and 7.2 billion USD in 2020.The global magnesium hydroxide nano market size is growing from 2017 to 2020, and the market size of magnesium hydroxide nano market is 1.18 billion USD in 2017 and 2020 Nano magnesium hydroxide market size is 1.94 billion U.S. dollars. 2020 China’s magnesium hydroxide market size is 1.457 billion U.S. dollars, of which, nano magnesium hydroxide market size is 763 million U.S. dollars, the market share is 52.38%.
China’s economy and society are developing continuously and rapidly, and the gap between industrial technology and developed countries is getting smaller and smaller, there is enough reason to think that China’s nano magnesium hydroxide industry will catch up and catch up with the developed countries in the world. Magnesium hydroxide industry is known as a sustainable sunrise industry, with the demand of Asia and the level of industrial production, the center of the world magnesium hydroxide market is shifting, and China becomes the fastest growing region of magnesium hydroxide market demand. Magnesium hydroxide is mainly used as filler in flame retardant, plastic, rubber, coating, sealant and other industries. In recent years, with the rapid development of these industries, magnesium hydroxide demand is further increasing, and flame retardant, plastic industry will play a leading role in the growth of demand for magnesium hydroxide.
First, the global flame retardant market size analysis
The average growth rate of global flame retardant market size is 3.6% from 2017 to 2020, and the global flame retardant market size is about USD 6.5 billion in 2017 and USD 7.2 billion in 2020.
Second, (different) application market share analysis
With the continuous development of modern industry, polymer materials such as plastics, rubber and synthetic fibers are widely used. However, the vast majority of these organic polymer compounds are combustible and can produce a large amount of deadly toxic gases during combustion. To solve this problem and improve the flame-resistance of synthetic materials, the most effective method is to add flame retardants. In this regard, flame retardants for the purpose of flame retardant research and material flame retardant technology has developed significantly in recent years, and has become one of the important components of the world’s industrial system.
At present, Asia, Western Europe and North America as the world’s major consumer of flame retardants. The United States and Western Europe as the birthplace of flame retardants, the industry developed earlier, and the market is mature and stable. The flame retardant industry in Asia started late, but with the rapid economic development of China and India, the flame retardant industry has grown rapidly and has become the world’s largest consumer market for flame retardants.
At present, foreign flame retardants are mainly inorganic systems, of which inorganic flame retardants account for more than 55% of the market share in Europe and the United States, and are mainly aluminum hydroxide and magnesium hydroxide. The production and consumption varieties of flame retardants in China are mainly organic flame retardants, and the proportion of inorganic flame retardant production and consumption is still relatively low. More than 80% of domestic flame retardants are halogen flame retardants.
Today, global annual consumption of flame retardants exceeds 2.25 million t. Aluminum hydroxide is the most used flame retardant, accounting for 38% of the total. 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%. Organophosphorus and other flame retardants, such as inorganic phosphorus compounds, nitrogen and zinc-based flame retardants account for the remaining 31%.
Among the applications in the industry, sales of flame retardants used in construction applications will see the strongest growth. The construction market will also account for the largest share of global demand for flame retardants, about 28%.
