China is in a period of rapid development. In the coming decades, the scale of construction in China will increase rapidly, and the demand for insulation building materials will also increase. A few days ago, the China Mayors Association released the "China Urban Development Report." The report pointed out that China has entered an accelerated period of urbanization, and it is expected that by 2020, 50% of the population will live in the city, and by 2050 there will be 75%. Live in the city.

In recent years, building energy conservation and emission reduction have become an important part of the national strategy. Beijing, Shanghai, Tianjin and other cities have successively issued policies concerning energy conservation and emission reduction.

The building insulation market supports polyurethane rigid foam demand. With the successive introduction of building energy conservation policies, energy-saving materials, especially as a green environmental protection polyurethane insulation material, have attracted wide attention from all walks of life. The properties of polyurethane materials are excellent, and they can prevent insulation from leaking while maintaining the insulation and heat insulation of roofs and external walls of energy-saving buildings. According to an architect, the polyurethane insulation material outside the wall has good insulation properties, high strength and is very firm.

According to statistics from relevant agencies, the consumption of polyurethane materials for construction reached 200,000 tons in 2009, and it is expected that the demand for polyurethane materials will approach 240,000 tons in 2010, with a growth rate of more than 15%. The increase in the size of the building supports the demand for insulation materials, which will provide favorable conditions for the growth of polyurethane rigid foam. Some experts predict that the construction of polyurethane rigid foam insulation will become a bright spot for the growth of aggregated MDI and rigid bubble PPG consumption in the near future.
