PolyurethaneAdhesivematerial is a multi-purpose synthetic resin with various product forms. The difference between polyurethane and other synthetic resins is that it has a rich variety of raw materials, many formula combinations, and a wide range of product forms and application fields. It is widely used in transportation ( Vehicles, ships, aircraft, roads, bridges), construction, machinery, electronic equipment, furniture, food processing, clothing, textiles, synthetic leather, printing, mining and metallurgy, petrochemicals, water conservancy, national defense, sports, leisure and entertainment, medical and other fields . For example, the thermal conductivity of rigid foam plastic is lower than that of other synthetic insulation materials and natural insulation materials. It can be cast on site and quickly formed. It is an increasingly versatile synthetic resin insulation material and is widely used in household appliances, pipeline insulation and Industrial thermal insulation; flexible foam plastics are widely used as cushion materials for beds, cars, boats, furniture seats, etc. due to their good elasticity and breathability. Polyurethane elastomer is famous for its wear resistance, low temperature resistance, high strength and oil resistance. It is an excellent special synthetic rubber used in various parts of mining and oil field machinery.
The development history of polyurethane is not as good as that of traditional synthetic resins, but it has developed rapidly. The total global polyurethane production was about 9.92 million tons in 2000 and about 13.75 million tons in 2005. Although it has experienced a global economic crisis, But it still reached 16.9 million tons in 2010, growing faster than conventional resin. Especially in China, the polyurethane industry has developed rapidly. In 2005, China's polyurethane products reached 2.91 million tons and about 4.3 million tons in 2010. The development rate is much faster than the global average.
Over the past 10 years, like other materials, polyurethane technology has developed rapidly, and some new technologies and products have emerged. For example, water-based polyurethane and other materials with better environmental protection have been greatly developed. The future development of the polyurethane market will be more extensive.
