The polyurethane material coming into the golden period of development

Update Time：2015-08-26 Author：admin Source：

In recent years, the polyurethane fireproof insulation material popular on the market for its unique molecular structure and special use function has made itself become a new material with widest scope of using, strongest applicability and it is the most popular material in the market.

In terms of physical structure and chemical composition, PU is short for polyurethane, it is composed of a polyisocyanate and a polyether polyol or polyester polyol, amine chain extender, a crossing agent and other raw materials of the polymer. By changing the varieties of raw materials or regrouping additives, it can significantly change the form of products and their functions and the finally get the product from soft to hard. It can be used to manufacture the plastics, rubber, fiber, rigid and flexible foams, adhesives and coatings and other functions.

At present, polyurethane is used widly in modern industries. Data shows that polyurethane demand today is growing with the rate of the world economy GDP 1.5-2 times. since 2000, global polyurethane applications bisically grows with the rate of double rate. Only 2010, the total amout of polyurethane reached 18.7million. Meanwhile, China's polyurethane’ production grows rapidly, in 2000, the PU production was only 1 million tons, in 2007, it is about 3.5 million tons, and by 2010, it has been up to 6.5 million tons. In addition with the rapid development of our Coating Market these years, so the demands towards PU is growing too. There are many varieties of PU coatings, and they are used widly, It generally has good mechanical properties, high solids content, with more stable performance, it is a promising paint variety. It is understood that Special polyurethane coating on the wood surface, car repair, as well as organics, electronics, etc. anticorrosion and waterproof applications function, have a good effect. Water is the main medium of aqueous polyurethane coating, it has a low VOC content, with low pollution and convinient for construction. It is one of the alternatives to solvent-d coatings.

PU is not only the necessary new material, but also it is used widly in construction industry at present. For the recent use of building fire insulation materials in China, polyurethane has become the first choice of energy-saving and insulation. Some analysis shows that in the early days, , due to many reasons such as scientific research, technology and the economy, most of China's construction buildings are high energy-consuming. In Northern China winter is cold, each year, maybe coal purchasing for warmness is much more than ever about 18 million tons; The national universally is with high temperature in summer, the full operation of the power sector still can not meet the peak demand, and have to cut the power to achieve building energy efficiency. Polyurethane sets fire insulation and energy saving in-one, and will act as the main force for China's building energy efficiency, which will bring great chance for PU industries.

Reportedly, China's Ministry of housing and Urban-Rural Development released that the long-dated target for building energy saving is : by 2010, new buildings of cities and towns can achieve energy saving 50%; By 2020, new buildings of the northern and coastal economically developed areas can achieve energy saving 65%. China has the world's largest construction market, currently more than 95% of our new buildings are still high-energy buildings. If we do not take effective actions to save energy, by the end of 2020, there will be 50 percent of the national energy will be comsumed on construction. Now the ratio of pu used on construction in China is not up to 10%, with the improvement of parameters requirements and standarding policies towards the insulation materials, we believe that PU material will have the largest market potential in the construction market.

It is reported that: global polyurethane market demand in 2010 was 13.65 million tons, it is expected to reach 17.946 million tons in 2016, with a compound annual growth rate of 4.7%. Watching the good prospects for the development of polyurethane industry, western developed countries have already entered the mature stage of development of polyurethane industries. Asian emerging market grows rapidly, especially for the strong growth in China market. Many multinational chemical enterprise have turned their focuses and R & D centers on business transferred to the Chinese market, which have greatly pushed the domestic polyurethane industry's rapid rise, and also brought development opportunities for domestic enterprises.
