Polyurethane insulation board, heat insulation board, Class-A fireproof board, interior wall, roof of roof, flame retardant and thermal insulation material

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. Applicable to; sunshine house top insulation, indoor ceiling, wall insulation, Beijing, Tianjin, Jiangsu, Zhejiang and Shanghai package!

         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, and is the lowest thermal conductivity of all thermal insulation materials.

2. Rigid polyurethane has moisture proof and waterproof properties. Hard ammoniaThe closed rate of ester 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 additionFlame retardant is a refractory self extinguishing material. Its softening point can reach above 250 degrees Celsius and only decompose at higher temperature. In addition, polyurethane will form product on its foam surface when it is burningCarbon, this carbon layer, helps to isolate the foam underneath. 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. It can be used in the normal service life of the structure, and it is dry and humidOr galvanic corrosion, and the external effects of insects, fungi or algae, or the destruction of rodents,Will not be destroyed.

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.
