聚氨酯保温板（Polyurethane insulation board） Polyurethane insulation board Catalog Polyurethane insulation board Two, product use Three, product features: Four, product specifications Five, performance index: Product shape and performance Edit this paragraph Polyurethane insulation board 1 、 rigid polyurethane, low thermal conductivity, good thermal performance. When the density of rigid polyurethane is 35 ~ 40kg/m3, the thermal conductivity is only 0.018~0.024w/ (m.k), which is about half of that of EPS. It is the lowest thermal conductivity of all thermal insulation materials at present. 2 、 rigid polyurethane has moisture-proof and waterproof properties. The closed rate of rigid polyurethane is more than 90%. It belongs to hydrophobic material. It will not increase moisture conductivity because of moisture absorption, and the wall will not seep. 3, rigid polyurethane fire retardant, flame retardant, high temperature. Polyurethane in flame retardant agent, a nonflammable, self extinguishing materials, softening point it can reach 250 degrees Celsius, only at higher temperature occurs when decomposition: in addition, polyurethane will form carbon on the foam surface in combustion, the carbon layer can isolate the foam. It can effectively prevent flame from spreading. Also, polyurethanes do not produce harmful gases at high temperatures. 4, because polyurethane board has excellent thermal insulation performance, in the same heat preservation requirements, can reduce the building envelope structure thickness, thereby increasing indoor use area. 5, resistance to deformation is strong, not easy to crack, surface stability, safety. 6, polyurethane material porosity structure is stable, basically is the closed cell structure, not only insulation performance is good, and antifreeze, sound absorption is good. The average life span of rigid foam polyurethane insulation structure can reach more than 30 years under normal conditions of use and maintenance. Can the normal conditions
