PIR Rigid Foam Insulation Board
1. Rigid polyurethane has low thermal conductivity and good thermal performance. When the density of rigid polyurethane is 35 ~ 40kg / m ³ The thermal conductivity is only 0.018 ~ 0.024w / (m.k), about half of EPS, which is the lowest among all thermal insulation materials.
2. Rigid polyurethane has moisture-proof and waterproof properties. The closed cell rate of rigid polyurethane is more than 90%, which is a hydrophobic material. It will not increase the thermal conductivity due to moisture absorption, and the wall will not seep.
3. rigid polyurethane fire, flame retardant, high temperature resistance. Polyurethane after adding flame retardant, it is a kind of flammable self extinguishing material, its softening point can reach more than 250 degrees Celsius, only at higher temperature will decompose: in addition, polyurethane in combustion will form carbon deposition on its foam surface, this layer of carbon will help isolate the following foam, and effectively prevent the flame from spreading. Polyurethane will not produce harmful gas at high temperature.
4. Due to the excellent thermal insulation performance of polyurethane plate, under the same thermal insulation requirements, it can reduce the thickness of the outer envelope of the building, so as to increase the indoor use area.
5. It has strong deformation resistance, is not easy to crack, and the finish is stable and safe.
