Polyurethane foam composite insulation board: Polyurethane foam composite insulation board refers to specialized factory production line, the polyurethane foam as a core material, or both sides of the composite sheet covered with some kind of decorative surface layer. Surface layer is typically to increase the bond strength of polyurethane foam insulation board and base surfaces, the UV and reduce transport damage. Features: 1, rigid polyurethane low thermal conductivity, good thermal performance. When rigid polyurethane density 35 ~ 40kg / m3, thermal conductivity of 0.018 ~ 0.024w / (m.k), equivalent to about half of the EPS, is the insulation material in all the lowest thermal conductivity. Building density 3.5 ~ 4KN / m3. 2, rigid polyurethane with moisture, water resistance. Rigid polyurethane closed cell ratio of above 90%, are hydrophobic material will not absorb moisture increases the thermal conductivity, the wall is not water seepage. 3, rigid polyurethane fire retardant, high temperature. After the addition of a flame retardant polyurethane, is a nonflammable, self-extinguishing material, its softening point can reach 250 degrees Celsius, will appear only at higher temperatures decomposition: In addition, polyurethane foams when burned in their carbon surface, this layer of carbon will help isolate the underlying foam. Can effectively prevent the spread of flame. Further, the polyurethane does not produce harmful gases at high temperatures. 4, since the polyurethane sheet has excellent insulation properties, achieve the same insulation requirements under, can reduce the thickness of the external structure of buildings, thereby increasing the indoor area. 5, resistance to deformation, not easy to crack, finishes stable and safe. 6, polyurethane material porosity structural stability, is essentially closed-cell structure, not only excellent thermal insulation properties, and freeze-thaw resistance, sound absorption or. The average life expectancy rigid polyurethane foam insulation structure, under normal use and maintenance conditions, can reach more than 30 years. We can do in the life of the structure under normal use conditions, in dry, wet or galvanic corrosion, and because insects, fungi or algae growth or damage due to the external factors rodents, etc., are not undermined. 7, comprehensive cost-effective. While the rigid polyurethane foam material is priced higher than the unit price of other traditional insulation materials, but the increased costs will be offset by a significant reduction in heating and cooling costs. Uses: large sheet of rigid polyurethane insulation can be used in sandwich panels, central air conditioning, building wall materials, cold storage, freezer, incubator, chemical tanks, and other fields. Performance indicators: specifications varieties, density range: (40-60kg / m3); length: (0.5 m -4 m); width: (0.5 m -1.2 m); Thickness: (20 mm -200 mm) . ● high precision cutting, thickness error ± 0.5mm, thus ensuring the flatness of the finished surface. ● foam fine, cell uniform. ● light weight, you can reduce the weight of manufactured goods from, lower than the traditional 30-60% of the product. ● compressive strength, can withstand the manufacturing process of the finished enormous pressure. ● Easy quality inspection, due to the removal of the epidermis, the quality of the sheet in the process of cutting around a glance, to ensure that the insulation effect of manufactured goods. Thickness according to user requirements and processing. Shen Yang-Ming Hui of insulation Building Material Co., Ltd. "Auspicious card" rigid polyurethane foam insulation board is the company through continuous production line of polyurethane industrial production to rigid polyurethane foam as insulation, reinforced membrane interfacial layer insulation composite board material . Enhanced web polyurethane foam adhesive on both sides of the relay through a strong and rigid polyurethane foam insulation layer of the composite, and strengthen the insulation layer and the base wall, the outer facing of adhesive strength, is widely used in insulation, sound insulation, fire-retardant, cold , corrosion, has become the construction, transport, petroleum, chemical, electric power, refrigeration and other industrial sectors essential insulation, sound insulation material. Specification: Standard size: 1200mm * 600mm (insulation thickness according to user needs) specific procurement standards, please call the business, detailed communication, sincere cooperation!
