New building materials of polyurethane insulation board
polyurethane insulation board structure with high intensity, physical and chemical performance is stable, there is no loose powder polystyrene particles insulation mortar cracking and obturator perlite vitrified beads insulation mortar dry shrinkage cracking.
polyurethane insulation board heat stability, good dimensional stability, safe use temperature as high as 120 ℃, and EPS, XPS board is only 70 ℃; Better dimensional stability than XPS plate, more than double the size coefficient rate & le; 1%.
is commonly used in the structure of the roof outer plate, the plate has good heat preservation, heat insulation, sound insulation effect, and polyurethane as auxiliary combustion, comply with the fire control safety. Polyurethane were added on the joint action, has the very high strength and stiffness, the lower plate is smooth level off, the line is clear, increase indoor aesthetic, flatness. Easy installation, short time limit, and beautiful, is a new kind of building materials. http://www。 juanzhibwb。 com
