 Polyurethane Features: 
 Polyurethane is a new kind of organic polymer materials, because of its superior performance has been widely used in many areas of the national economy. 
 A low thermal conductivity of rigid polyurethane thermal performance. 35 ~ 40kg/m3 rigid polyurethane density, thermal conductivity of only 0.018 0.024w / (m.k), equivalent to approximately half of the EPS, which is the lowest thermal conductivity of all insulation materials. 
 2, rigid polyurethane moisture-proof, waterproof performance. Rigid polyurethane closed-cell rate in more than 90% of a hydrophobic material, will not increase the thermal conductivity due to moisture absorption, as the use of external insulation materials, the walls are not signs of water seepage. 
 3, the rigid polyurethane fire retardant, high temperature. Polyurethane additive flame retardant, a flame retardant self extinguishing material, and its softening point above 250 degrees Celsius, only to appear at higher temperatures, decomposition: In addition, polyurethane foam when burned in their formed on the surface of carbon deposition, this layer of coke will help isolate the following bubble. Can effectively prevent the spread of flame. Moreover, the polyurethane at high temperatures do not produce harmful gases. 
 4, the polyurethane material porosity structure and stability, is basically a closed cell structure, not only excellent thermal insulation properties, and resistance to freezing and thawing, the acoustic properties. The average life expectancy of the structure of rigid polyurethane foam insulation, under conditions of normal use and maintenance, can reach more than 30 years. Able to do in the structure of the life of the normal use conditions, in dry, damp, or electro-chemical corrosion, as well as insects, fungi or algae growth due to external impact of the destruction of rodents, are not damaged. 
 Polyurethane composite Class A fire insulation ultra-thin stone veneer on Hai Bangti ultra-thin stone granite stone binder paste in a special belt to strengthen the column polyurethane insulation composite board. The polyurethane composite plate once molding, industrial production, to avoid the wet work of the construction site, the the monomer installation, effectively preventing the exterior insulation and finish systems cracking, peeling and the hidden dangers of hot and cold bridge. As a result of advanced patented construction technology, to make polyurethane polymer mortar composite class A fire insulation effective bonding of ultra-thin stone veneer wall, thereby ensuring the polyurethane composite class A fire insulation thin stone ornaments the durability of the panel, two fifth freeze-thaw test, the indicators are at or better than national standards. Truly durable and does not fall off. The company also strengthen the use of special aluminum alloy special pendant, the polyurethane composite class A fire insulation thin stone veneer and wall connections, and a unique wet paste plus CLADDING combination of installation, and more to ensure high-level the safety of the building, completely solve the paste on the external walls of fire insulation layer of ultra-thin granite. 
 The polyurethane composite plate the outside can be arbitrarily applied, paste, decorative coatings and external decorative finishes, reflecting the flexibility of thermal insulation composite panels decorated. "Bangti ultra-thin stone cutting machine (patent number: 201110049122.6) the production of ultra-thin granite, thin marble and other stone, directly paste polyurethane composite Class A fire insulation thin stone veneer, thin stone thickness can be processed to 3mm, greatly reducing the weight of the external walls of a class A fire insulation polyurethane composite panels, reducing the weight of the building body to protect the building structure, to extend the useful life of buildings. Relative to the traditional granite stone hanging construction with the advantages of low cost, safe and beautiful, short construction period, a more fundamental solution to the traditional external decorative insulation, insulation can not be directly the problem of external decorative. 
 Specifications: 
 300mm × 300mm, 300mm × 600mm, 600mm x 600mm, 600mm x 1200mm, 600mm x 1800mm, 800mm × 800mm, but also according to the need to order more; In addition the company also can process all kinds of granite plates, marble, class A fire insulation composite panels external decorative composite panels, marble tile, travertine, external decorative glass cotton insulation composite panels, extruded polystyrene board sandwich external decorative composite panels, ultra-thin stone gray linen, white linen, ultra-thin granite external walls of stone and so on. 
 Thickness: 3mm ~ 10mm
