Train roof, floor and wall panels can be rigid polyurethane foam insulation, which is particularly important for low-temperature areas of the train. All with polyurethane insulation train, six sides of the average spraying 60ram thick rigid polyurethane foam, each car about 900kg. The train will travel in the outdoor temperature of -30 ℃ area, the car can still be maintained at 20 ℃, with the general blanket material can only be around 0 ℃, showing excellent cold performance.
Japan with glass fiber reinforced rigid polyurethane foam made of composite sheet, and then a number of composite sheet paste into a "synthetic sleepers", after 10 years of laying application test is not damaged, not maintenance, life expectancy of up to 60 years, The long-term economic assessment is comparable to 30% for wood sleepers. Due to the light weight, durability, has been used in bridges, tunnels and fork and other places.
