Polyurethane composite panel production line, rigid polyurethane low thermal conductivity, good thermal performance. Rigid polyurethane capacity twilight 35 ~ 40kg/m3 Thermal conductivity of only 0.018 g ~ 0.023w / (m.K), equivalent to about half of the EPS, all insulation materials is the lowest thermal conductivity. Rigid polyurethane moisture-proof, waterproof performance. The rigid polyurethane Obturator rate belong to the hydrophobic material, not more than 90%, due to moisture absorption to increase the thermal conductivity, the walls are also not seepage. 3, rigid polyurethane fire, flame retardant, high temperature. Polyurethane additive flame retardant, a flame retardant self-extinguishing material, its softening point up to 250 degrees Celsius or more, only to appear in the higher temperature decomposition: addition, polyurethane burning in foam formed on the surface of ash, this layer of ash can help isolate the foam below. Can effectively prevent the spread of fire. Moreover, the polyurethane at high temperatures do not produce harmful gases. Polyurethane sheet with excellent thermal insulation properties, to achieve the same insulation requirements can reduce buildings external structure thickness, thereby increasing the indoor area. Resistance to deformation, not easy to crack, finishes, security. 6, the porosity of the structure of the polyurethane material is stable, basically a closed-cell structure, not only excellent thermal insulation properties, and freeze-thaw resistance, sound absorption or a. The average life expectancy of the structure of rigid polyurethane foam insulation, under normal use and maintenance conditions, can reach more than 30 years. Be able to do in the lifetime of the structure under normal use conditions, in the dry, wet or galvanic corrosion, as well as insects, fungi or algae growth, or, are not damaged due to the destruction of rodents and other external impacts. 7, the low overall cost-effective. Rigid polyurethane foam material unit price than other traditional insulation materials unit price, but the increase in cost will significantly reduce heating and cooling costs and offset. The product uses the Company's production of rigid polyurethane insulation sheet can be widely used for color steel sandwich panel, central air conditioning, building wall materials, cold storage, cold rooms, incubators, chemical tanks and other fields. Features: ● specifications varieties, bulk density range: (40-60kg/m3); length range: (0.5 m -4 m); width range: (0.5 m -1.2 m); thickness range: (20 mm - 200 mm). ● high precision cutting, thickness error disabilities 0.5mm, thus ensuring the flatness of the surface of the finished products. ● dense foam cell uniform. ● light weight, can reduce the self-weight of the finished goods, is 30-60% lower than traditional products. Compressive strength, can withstand the enormous pressure in the process of manufacturing finished products. ● facilitate the inspection of the quality, and removed during the cutting process around the epidermis, the quality of the sheet material at a glance, to ensure the insulation effect of the manufactures. Thickness of the production and processing according to user requirements, product specifications rigid polyurethane foam bubbles block (the company to provide a different density foam blocks used to manufacture a variety of profiles) varieties of polyurethane foam the bubbles block (in mm) specifications 4000 × 1200 × 1000 2000 × 1200 × 1000 the board density rigid polyurethane foam plate varieties polyurethane 40-60kg / m Specifications Length :4000-500mm width :1200-500mm thickness: according to customer requirements customized special specifications can be foam block any cutting
