Polyurethane foam wall panels Advisory: 18240214099 
 (1) flame-retardant polyurethane flame retardant, a flame retardant self-extinguishing materials to form a fire protection system, can effectively prevent the spread of fire. 
 (2) low thermal conductivity of 0.019 ~ 0.024W / (m? K) due to high strength polyurethane adhesive without any adhesive and anchors, is a natural adhesive material to form a continuous insulating layer, to ensure insulation material and the wall together and effectively block the thermal bridge. 
 (3) The bending strength of rigid polyurethane foam is a strength ratio (the higher material strength of the material and the bulk density ratio), its performance is better than foam polystyrene, Yan Jin, and other materials as insulation materials ability to resist external forces. strong. 
 (4) the water tightness of non-absorbent polyurethane materials have excellent water vapor barrier properties, the material does not contain water, water absorption is very low, can block the penetration of water and water vapor, so that the wall to maintain a good stable adiabatic conditions, and other insulation materials is difficult to achieve. 
 (5) does not decay. 
 (6) does not moth-eaten rat-bite. 
 (7) The porosity of of Nijhuis polyurethane material structural stability, is basically a closed hole, so not only excellent thermal insulation properties, and freeze-thaw resistance, sound absorption, or 
 (8) the temperature range of polyurethane is a flexible deformation of materials, it resist deformation capacity of the outside world, the external forces and temperature deformation of dry warm deformation under the action, not easy to crack, to ensure the stability of the system and durability. 
 (9) environmental performance is good for exterior insulation and polyurethane materials of a high chemical stability, acid, alkali, heat-resistant, polyurethane solvent-free, non-fluorinated lithium Aung type, and thus will not harmful gases, will not harm the environment.
