pu insulation board Rigid foam polyurethane board has low thermal conductivity and good thermal characteristics. When a piece of polyurethane is used for 35~40kg/m3, the thermal conductivity is only.018~0.024w/(m.k), about half of EPS, is the least thermal conductivity of each component of the process.
pu insulation board rigid foam polyurethane board in the transmission of stealing, in order to prevent the characteristics. A piece of polyurethane in front of 90%, is hydrophobic relief, is not easy to increase thermal conductivity due to moisture absorption, the external wall is not easy to water.
pu insulation board rigid foam polyurethane board heat insulation, convenient, industrial resistance. After polyurethane participates in the convenience, it is a box of inflammable flumming relief plate. Its carrying point can go to the front of the Celsius degree, only when the humidity is quite high, the statistics are generated: in addition, polyurethane in the incineration function of its device principle to form carbon deposit, which helps to guard against the next device. Can effectively prevent from flame inheritance. In addition, polyurethane under the industry also does not lead to useless high.
Will not same polyurethane paint in good combustion heat insulation protection fire waterproof and fireproof isolation to prevent heat insulation characteristics, under the same to constitute the adverse effect, can make the analysis of the building envelope estimate, also increase the indoor use area.
pu insulation board rigid foam polyurethane board to resist the loss of beautiful operation ability, sticky alkali resistance, finish stable, safe.
The porosity of pu insulation board rigid foam polyurethane board is stable, generally speaking, it is composed of closed pores, and it has good composition characteristics, and besides, it has freezing and thawing resistance and sound absorption. Rigid foam polyurethane is composed of more reasonable glass, which can be used and serviced in a wide range of conditions. It is recommended that under the conditions of widespread use in the glass phase of the composition, it is not easy to give damage in very dry, water drying or electrochemical corrosion, and the first choice of the best species of insects, fungi or algae may be different from the damage of rodents and other external causes.
pu insulation board rigid foam polyurethane board is generally cost-effective. Although the salary of a polyurethane unit is higher than that of a typical relief plate, the improved desulfurization is not offset by a large degree of analysis of heating and cooling desulfurization.
