Summary：　Polyurethane foam is currently the best insulation and energy-saving material, with better performance indicators than traditional XPS and EPS external insulation systems. This type of external insulation system technology has received attention from relevant leaders and experts in various provinces and cities of the country. The Science and Technology Department of the Ministry of Construction has established a working group to promote the energy-saving application of polyurethane buildings, and held the "International Exchange Conference on Polyurethane Wall Energy saving Application Technology" in Beijing in mid October 2005. Nearly 100 representatives from energy-saving wall renovation offices and design and development units of the Science and Technology Department (Construction Commission) of the Construction Department (Construction Commission) of various provinces, municipalities, autonomous regions, and municipalities directly under the central government participated.

China is the largest refrigerator producer in the world. In 1998, 80000~100000 tons of rigid foamed plastics were consumed, and 15% of them were used as thermal insulation materials for oil transmission pipelines, chemical storage tanks and industrial equipment; Building materials are another large application field of rigid polyurethane foam. In 2000, the construction industry consumed more than 70000 tons of rigid PUR foam. Due to the rapid development of China's construction industry, 10% of foamed plastics are used for building heat insulation, sound absorption, decorative materials and activity rooms; Insulation materials used for transportation account for 10%; Others account for 7.5%, with significant consumption of furniture, clothing, bicycles, and other items.

In addition, the development of China's automobile industry and motorcycle industry also provides a broad market for soft PUR foam. According to experts' predictions, due to the excellent plasticity and practical properties of polyurethane, its application in automobiles is increasingly expanding. It is expected that the demand for polyurethane in China's automotive industry (excluding Taiwan Province) will reach 44100 tons in 2005, including 30400 tons for sedans and jeeps, 3000 tons for heavy-duty sedans, 7200 tons for light-duty vehicles, and 500 tons for micro cars. The average usage per vehicle will reach 14.71 kg

Polyurethane foam plastic is the most important polyurethane product, which has a wide range of uses and excellent performance: soft PUR foam plastic and semi-rigid PUR foam plastic are mainly used in furniture cushion and decorative materials, vehicle cushion materials, carpet bottom lining, clothing lining, building sound-absorbing materials, sports cushion materials, as well as mattress and instrument packaging materials. The main uses of molded soft polyurethane foam are car seat cushion, motorcycle seat cushion, bicycle seat cushion, etc; Rigid polyurethane foam is mainly used as thermal insulation materials in refrigerators and cold storage industries, accounting for 57.5% of the total consumption of rigid polyurethane foam
