• Rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35~40kg/m3, the thermal conductivity is only 0.018g~ 0.023W /(M.K), about half of EPS, is the lowest thermal conductivity of all thermal insulation materials.
•  Polyurethane sandwich panels have moistureproof and waterproof properties. The closed cell rate of rigid polyurethane is more than 90%, which belongs to hydrophobic materials. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep. 
• Polyurethane cold storage panels are fireproofing , flame retardant, high temperature resistance. Polyurethane, when added with flame retardants, is a non-flammable, self-extinguishing material with a softening point of more than 250 degrees Celsius, breaking down only at higher temperatures: in addition, polyurethane burns to form a layer of ash on the surface of its foam, which helps insulate the underlying foam and can effectively prevent the spread of fire. Polyurethane also does not produce harmful gases at high temperatures.
• Due to the excellent thermal insulation performance of polyurethane sheet, it can reduce the thickness of building envelope and increase the indoor use area under the same thermal insulation requirements.
• Polyurethane material has stable porosity structure, which is basically closed cell structure. It not only has excellent thermal insulation performance, but also freeze-thaw resistance and sound absorption.The average life of rigid foam polyurethane insulation structure can reach more than 30 years under normal use and maintenance conditions.The cost of rigid foam polyurethane insulation board is relatively high, but the increased cost will be offset by a significant reduction in heating and cooling costs.
