Pu sleepers are highly concerned by the industry and become a hot research topic

at present, Pu sleepers have been highly concerned by the PU and railway industry, and are a hot topic in the global PU material industry. According to the report on the highlights of the development of China's polyurethane industry, according to the national long-term plan for the development of high-speed railway, in order to meet the requirements of high-speed train speed increase, the development of Pu sleepers to replace or partially replace concrete sleepers will be the future development trend

pu sleepers use glass fiber reinforced rigid PU microporous elastomer, which has excellent properties such as high specific strength, shock absorption, noise reduction, electrical insulation resistance, high durability and environmental protection. At present, it has been highly concerned by Pu and railway industry, and is a hot topic in the global PU material industry. According to the long-term plan of the national development of high-speed railway, the measured force value will be smaller in order to adapt to the slow loading rate. In response to the requirements of high-speed train speed increase, the development of Pu sleepers to replace or partially replace concrete sleepers will be the future development trend

according to foreign experience, about 1800 sleepers are required for 1km high-speed railway. The market scale of Pu sleepers for 7000km high-speed railway will reach 50billion yuan, which will undoubtedly bring huge market space to the new PU elastomer

in Japan, Pu sleepers have been used for 25 years, with an application volume of 3million, and have been applied on the Shinkansen rail line of Japanese high-speed trains. Pu sleepers made in Japan have also been partially used in Guangzhou, Shanghai and Taiwan in China. In addition, such Pu sleepers have also been used in Vienna Metro in Austria. Bayer materials technology has successfully made Bayflex microporous PU elastomer sleepers, which are planned to be used in the construction of China's high-speed rail
