Product brief:1、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 0.018~0.024w/ (m.k), equivalent to about half of the EPS, is the thermal conductivity of thermal insulation material in all.

2、 Rigid polyurethane has moisture proof and waterproof properties.The closed rate of rigid polyurethane is more than 90%, which belongs to hydrophobic material. It will not increase the thermal conductivity because of moisture absorption, and the wall will not seep.
3、 Rigid polyurethane fire retardant, flame retardant, high temperature resistant.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. The flame spread can be effectively prevented. Moreover, polyurethane does not produce harmful gas at high temperature.
4, due toPolyurethane board has excellent heat insulation performanceUnder the same insulation requirements, it can reduce the thickness of the building envelope, thereby increasing the indoor use area.
5、 Anti deformation ability is strong, not easy to crack, surface stability, safety
6、 Polyurethane material has a stable porosity structure and is basically a closed cell structure, which not only has excellent thermal insulation properties, but also has freeze-thaw resistance and sound absorption property.The average life of rigid foam polyurethane insulation structure can reach more than 30 years under the condition of normal use and maintenance. Can the normal conditions of use in the lifetime of the structure, in dry and wet or electrochemical corrosion, as well as insects, fungi or algae or rodents due to destruction of the external factors, will not be destroyed.
7、 Comprehensive cost-effective.Although the rigid polyurethane foam material than the price of other traditional insulation materials of high cost, but the cost will be increased by heating and cooling costs are substantially reduced and offset.
