< P> in the period of high speed to carry out in China, the scope of construction in the future decades China will increase rapidly, thermal insulation building materials demand growth. Released recently, the China association of mayors of Chinese cities report, the report pointed out that China has entered the accelerating period of urbanization, estimates that by 2020, there will be 50% of the population living in urban areas, in 2050, 75% of people living in the city. In recent years, the construction energy conservation and emissions reduction has become an important local country strategy, Beijing, Shanghai, tianjin and other cities have successively introduced the related policies of energy saving and emission reduction. < / P> < P> building support for rigid polyurethane insulation market. As the developed construction energy conservation policy, energy-saving materials, especially as a green pu heat preservation material, absorb the attention from all walks of life. Polyurethane material, have excellent performance can meet the energy saving of building roof and exterior wall heat preservation and heat insulation at the same time, also can avoid insulation layer water penetration. Architect said, pu heat preservation material outside the wall heat preservation performance is good, high strength, very strong. < / P> < P> according to relevant organizations, building of polyurethane raw materials consumption in 2009 reached 200000 tons, the estimated 2010 polyurethane raw materials will be close to 240000 tons, the demand for growth beyond 15%. Increase of construction scope, support the demand for thermal insulation material, it will give polyurethane rigid demand growth to provide favorable conditions. Some experts predict, the polyurethane hard foam building insulation will be the future for a period of time the rigid polymerization MDI and PPG consumption growth. < / P>
