As a polymer material with excellent performance, polyurethane has become the fifth largest plastic after polyethylene, polyurethane, polypropylene, and polystyrene. The total global output has exceeded 10 million tons per year. Polyurethane high-pressure foaming equipment essential. In recent years, my country's polyurethane industry has achieved rapid development and has been widely used in refrigerators, containers, leather, shoemaking and textiles. Approximately 49% of building insulation materials in developed countries such as Europe and the United States are polyurethane materials, but in my country, this proportion is still less than 10%.
The application fields of polyurethane in the development of the national economy will be very extensive, and the scale of application will continue to expand. Polyurethane high-pressure foaming equipment will be widely used in building energy conservation, automobiles, home appliances, textiles and other industries. China’s accelerated urbanization process and increased investment in high-speed railways have brought huge market opportunities for the polyurethane industry. China has become a major producer and consumer of polyurethane in the world, with the world's largest output of most raw materials and products, but in terms of per capita consumption, there is still a big gap compared with developed countries, and it is still a low polyurethane consumer. Moreover, the current capacity of major polyurethane raw materials is rapidly expanding, and the pressure of overcapacity in the industry has increased significantly. Therefore, expanding the application of polyurethane through product transformation and upgrading is not only the need of the downstream market, but also the inherent demand of the development of the industry.
The polyurethane industry should seize the opportunity, unswervingly promote industrial upgrading, and regard meeting the needs of the national economy and the people's livelihood as a means of structural transformation. Due to the rapid development of my country's building energy conservation, it is expected that the market for rigid foam polyurethane insulation materials used for building insulation will show a leapfrog development.
Industry analysts said that due to the late start of domestic polyurethane high-pressure foaming equipment, the overall industry maturity is low, large enterprises are relatively small, and the industry concentration is low, resulting in a relatively chaotic overall industry competition pattern. However, with the development, the industry will become more and more standardized, and some mixed products are bound to be eliminated.
From a global perspective, building energy consumption accounts for about 30% of the total energy consumption of the whole society. At present, my country is the world's largest construction market, and construction is not only a major energy consumer but also the main battlefield for future energy conservation. It is imperative to promote building energy efficiency.
Vigorously promote building energy saving, it is bound to drive the rapid development of the polyurethane rigid foam industry. According to related reports, China has the world's largest construction market, and at present, more than 95% of new buildings in China are still high-energy buildings. According to the specific goals of the Ministry of Urban and Rural Housing Construction for building energy conservation, by 2010, new buildings in cities and towns across the country will achieve energy savings of 50%, and by 2020, new buildings in the northern and coastal economically developed areas will achieve energy savings of 65%. The proportion of domestic rigid foam used in insulation materials in the construction field is about 10%. Therefore, it can be seen that the use of polyurethane rigid foam is increasing year by year, and the overall competition is fierce. The future development of the polyurethane rigid foam industry is considerable.
