my country’s polyurethane industry started Beganin the late 1950s. In 1958, Dalian Dyestuff Factory began to study toluene diisocyanate. In 1962, it built a toluene diisocyanate production device with an annual output of 500 tons, laying the foundation for my country’s polyurethane industry. In 1959, the Shanghai Light Industry Research Institute began research on polyurethane foam. At the same time, the Jiangsu Institute of Chemical Industry also conducted experimental research on polyurethane resin and raw materials.
In 1964, Jiangsu Institute of Chemical Industry and Nanjing Plastics Factory Cooperation, polyether polyurethane flexible foam was put into pilot production. 1966China’s polyurethane industry began in the late 1950s.

Shandong Yantai Spandex Factory introduced Japanese technology and was established in my country in October 1989苐a spandex yarn production factory.
my country’s polyurethane industry had a certain scale of small industrial equipment production before 1978. For a long period of time, due to the weak foundation of raw material supporting industry and application development, the development was slow. At that time, the total production capacity of polyurethane resin Only 11,000 tons, the output is only about 5,000t, and there are only more than 30 varieties. This stage is the initial pioneering stage of my country’s polyurethane industry. In October 1984, the “National Polyurethane Industry Collaboration Group” was established. The collaboration group consists of six professional groups: polyether, isocyanate, foam plastics, elastomers, adhesives, and coatings. The “Polyurethane Industry” editorial department was also established. In December 1994, with the approval of the state, the China Polyurethane Industry Association was officially established.
Since font>After China began to implement the reform and opening up policy in the late 1970s, Shandong Yantai Synthetic Leather Factory introduced a 10,000 tons/year MDI/PAPI device from Japan and put it into production in 1984. This is China’s 苐 A set of equipment for producing MDI using contemporary advanced technology, enabling MDI production to meet the needs of the domestic market. Yinguang Chemical Industry Company introduced German technology and equipment and built and put into operation a 20,000 tons/year TDI device in 1990. In 1987, Shenyang Petrochemical Plant introduced a 10,000-ton/year polyether polyol unit from Italy and put into operation. In 1989, Tianjin Petrochemical Company No. 3 Plant and Jinxi Chemical General Plant each imported 20,000-ton/year polyether polyol units from Japan. Put into production successively. These three sets of devices have a high degree of automation and advanced technology, and their products meet the requirements of users in the domestic market. Due to the establishment of polyurethane raw material production equipment and the introduction of advanced equipment for the production of polyurethane products, especially after the 1990s, my country’s polyurethane industry has developed more rapidly, with output, variety, and technical level increasing and improving exponentially. The average annual growth rate of output remains above 15%. In 1998, the total output of polyurethane resin reached 770,000 tons. According to data from foreign consulting company IAL, China’s polyurethane production was only 7,000 tons in 1982, but reached 2.9 million tons in 2005, with an average annual growth rate of 25%. It is estimated that it will reach 4.3 million tons in 2010, with an average annual growth rate of 8.1%.
According to Chinese polyurethane According to industry association statistics, mainland China’s polyurethane product consumption in 2003 was 2.104 million tons, in 2004 it was 2.59 million tons, in 2005 it was 3 million tons, and in 2006 it was estimated to be about 3.6 million tons. my country’s polyurethane resin output has an average annual growth rate of more than 20%, which is about twice the GDP growth rate. Among them, rigid foam, elastomer, synthetic leather and spandex fiber are growing the fastest. The rapid growth of rigid foam is mainly due to the demand for energy-saving and thermal insulation of buildings.
Currently, Synthetic leather slurry, sole solution, spandex and coatings account for a large proportion in my country’s PU product consumption structure. The total consumption of PU products in 2008 was 4.8 million tons (including 1.6 million tons of solvents).
