Product introduction,1. Rigid polyurethane has low thermal conductivity and good thermal performance. When rigid polyurethanedensityFor 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 thermal conductivity of all thermal insulation materials.
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 resistance. 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 sheetIt has good heat insulation performance, and can reduce the thickness of building envelope and increase indoor environment when the same insulation requirement is achievedUse area。
5, resistance to deformation is strong, not easy to crack, surface stability, safety.
6, polyurethane material porosity structure is stable, basically is closed cell structure, not only insulation performance is good, and freeze-thaw resistance, sound-absorbing property is good. The average life of rigid foam polyurethane insulation structure can reach more than 30 years under the condition of normal use and maintenance. Under the normal service life of the structure, it can not be destroyed in dry, wet or electrochemical corrosion, and because of insects, fungi or algae growth, or because of the destruction of rodents and other external effects.
7, comprehensive cost-effective. Although the unit price of rigid polyurethane foam material is higher than that of other traditional thermal insulation materials, the cost will be offset by a substantial reduction in heating and cooling costs.
