Polyurethane sandwich panel is a kind of heat preservation performance is good, high strength of the retaining structure with boards. With good heat insulation performance of PU as the filling material, the outside is made of color steel sandwich type library board, can reduce the heat transfer due to the temperature difference between inside and outside, in order to achieve the maximum efficiency of refrigeration, cold storage system.
Standard Honor PU sandwich panel thickness is 50、75、100、120、150、175、200、250mm.
Honor PU sandwich panel is connected by bump tank eccentric hook lock box, two panels’' gap is sealed by sealing material. PU sandwich panel technical parameters：
PU sandwich panel thickness error is ±2mm; fire is self-extinguished from fire for 3~5s; heat conductivity coefficient≤（0.023±0.001）W/m.k; inside of the entire sandwich board has no endless void cracking phenomenon and uniform density; stable size≤1%; percentage of close area≧90%; Water absorption≤3%;
Thickness of double-sided color steel is national standard (0.5mm); both sides of the insulation board is connected by bump slot eccentric hook.
