Characteristics Of Polyurethane Wall Panels

Hard 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), which is about half of EPS and has the lowest thermal conductivity among all insulation materials.

1. Hard 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), which is about half of EPS and has the lowest thermal conductivity among all insulation materials.

2. Hard polyurethane has moisture-proof and waterproof properties. The closed cell rate of rigid polyurethane is over 90%, which belongs to hydrophobic materials. It will not increase its thermal conductivity due to moisture absorption, and the wall will not leak water.

3. Hard polyurethane is fire-resistant, flame-retardant, and heat-resistant. Polyurethane, after adding flame retardants, is a flame-retardant self extinguishing material with a softening point of over 250 degrees Celsius, and only decomposes at higher temperatures. In addition, polyurethane will form carbon deposits on its foam surface when burning, which will help isolate the foam below. Can effectively prevent the spread of flames. Moreover, polyurethane does not produce harmful gases at high temperatures.

4. Due to the excellent thermal insulation performance of polyurethane panels, they can reduce the thickness of building envelope structures and increase indoor usable area while meeting the same insulation requirements.

5. Strong deformation resistance, not easy to crack, stable and safe finish.

6. Polyurethane materials have a stable porosity structure, basically a closed cell structure, which not only has excellent insulation performance, but also has good frost resistance and sound absorption. The average lifespan of hard foam polyurethane wall panels can reach several decades under normal use and maintenance conditions. They can withstand dry, humid, or electrochemical corrosion, as well as external factors such as insect, fungal, or algal growth or damage from rodents, without being damaged during the structural lifespan under normal use conditions.
