Concrete Slab or precast concrete panels

The primary use is mainly concrete cast panels or precast concrete panels and cement mortar layer . Concrete mixing plants , both as a waterproof layer , but also as the insulation layer ; some as one of a waterproof layer. Rigid polyurethane foam used for roofing projects , can play the role of waterproof insulation can also play the role . In all building insulation materials, the thermal conductivity of ready mix concrete plant polyurethane lowest 0.033W / (m · K); internal structure of the sealing rate of ≥ 92%, foaming of the surface to form a smooth layer film, which obturator close to 100% , with a high hydrophobic ; density of 40kg/m3 the strength > 1.5MPa; have a certain flexibility , elongation of 10% ; on metal, concrete , masonry, wood, glass has good adhesion.
