Metal insulation polyurethane sandwich panels

Rigid polyurethane has low thermal conductivity and good thermal properties. 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 that of EPS, which is the lowest of all thermal insulation materials at present. Rigid polyurethane has moisture-proof and waterproof properties. The closed porosity of rigid polyurethane is more than 90%, which belongs to hydrophobic material. Rigid polyurethane fire resistant, flame retardant, high temperature resistance. Polyurethane, after adding flame retardants, is a refractory self-extinguishing material, with a softening point of more than 250 degrees Celsius and decomposition only at higher temperatures: in addition, when the polyurethane burns, it forms carbon deposits on the surface of its foam. This layer of carbon helps isolate the foam below. Yes.
