2, hard polyurethane with moisture-proof, waterproof performance. Closed cell rigid polyurethane at a rate above 90%, belongs to the hydrophobic material due to moisture absorption, will not increase the coefficient of thermal conductivity, the walls are not seepage.
3, rigid polyurethane fire, flame retardant, high temperature resistant. Polyurethane in flame retardant agent, is a non flammable self extinguishing materials, softening point it can reach 250 degrees Celsius, the decomposition will appear at higher temperatures. In addition, polyurethane will form carbon on the foam surface in combustion, the carbon layer can isolate the foam. Can effectively prevent the spread of flame. Moreover, polyurethane at high temperature does not produce harmful gases.
4, because the polyurethane sheet has good insulation properties, with the same insulation requirements, can reduce the thickness of building envelope, thereby increasing the use of indoor space.
5, strong resistance to deformation, not easy to crack, surface stability and safety.
6, the polyurethane material porosity structure is basically stable, closed cell structure, good insulation property, and freeze-thaw resistance, sound absorption. The average life span of rigid polyurethane foam insulation structure, in normal use and maintenance conditions, can reach more than 30 years. Can the normal conditions of use in the lifetime of the structure, in dry and wet or electrochemical corrosion, as well as insects, fungi or algae or rodents due to destruction of the external factors, will not be destroyed.
7, a comprehensive cost-effective. Although the rigid polyurethane foam material than the price of other traditional insulation materials of high cost, but the cost will be increased by heating and cooling costs are substantially reduced and offset.
