Polyurethane insulation board (chemical name: PU) 1, rigid polyurethane thermal conductivity is low, good thermal performance. When the rigid polyurethane density of 35 ~ 40kg / m3, the thermal conductivity of only 0.018 ~ 0.023w / (m.k), equivalent to about half of the extruded board (EPS), is the thermal insulation of all the best thermal conductivity of. 2, rigid polyurethane with moisture, water resistance. Rigid polyurethane closed porosity of 95% or more, are hydrophobic materials, will not increase the thermal conductivity due to moisture absorption, the wall will not seepage. 3, rigid polyurethane fire, flame retardant, high temperature. Polyurethane after the addition of flame retardant, is a flame retardant self-extinguishing material, its softening point can reach 250 degrees Celsius above, only in the higher temperature will be decomposed: In addition, the polyurethane in the combustion of its foam The surface of the formation of carbonized layer, this layer of carbonization layer to help isolate the following foam, can effectively prevent the spread of fire. Moreover, the polyurethane does not produce harmful gases at high temperatures. 4, because the polyurethane sheet has excellent insulation properties, to achieve the same insulation requirements, can reduce the thickness of the building outside the envelope, thereby increasing the indoor use area. 5, anti-deformation ability, easy to crack, finishes stable and safe. 6, polyurethane material porosity structure is stable, basically closed-cell structure, not only excellent insulation properties, and anti-freeze-thaw, sound absorption is also good. The average life expectancy of the polyurethane foam insulation structure can reach more than 30 years under the condition of normal use and maintenance. Can be done under normal conditions of use in the life of the structure, in the dry, wet or electrochemical corrosion, and because of insects, fungi or algae growth or damage due to rodents and other external factors, will not be destroyed. 7, comprehensive cost-effective. Although the price of rigid polyurethane foam is higher than that of other traditional insulation materials, the increased cost will be offset by a significant reduction in heating and cooling costs.
Product range: Length range: (0.5 m -4 m); Width range: (0.5 m -1.2 m); Thickness range: (20 mm -200 mm) Size: (40-60 kg / m3) Cutting precision, thickness error of 0.5mm, thus ensuring the smoothness of the finished product surface. Foam fine, cell evenly. Light weight, can reduce the weight of manufactured goods, lower than the traditional 30-60%. Compressive strength, can withstand the great pressure in the process of manufacturing finished products. To facilitate the quality of the inspection, as in the cutting process to remove the surrounding skin, the quality of the plate at a glance, to ensure that the finished product insulation effect.
