2022-07-13
As early as the 1930s, polyurethane (PU) was developed by German scientists. German scientists condensed liquid isocyanate and liquid polyether or glycol polyester to form a new material. The physical property parameters of this material are different from those of polyolefin materials at that time. Scientists named it polyurethane. With the end of the Second World War, the chemical manufacturing industry in the United States flourished, and in the 1950s, polyurethane flexible foam was synthesized, which was an important landmark research in the chemical industry at that time and provided a solid technical foundation for the future development of the polyurethane industry.
