Material instruction
1)Suface sheet: Usually the surface sheet of PUR or PIR sandwich panels is PPGI or PPGL steel color coated sheets.PPGI is prepainted galvanized coated steel and PPGL is prepainted Al-Zn coated steel.For coating type,you could choose PE, PVDF, HDP, SMP,ect.Our strategic cooperation brands are Bluescope, Bao-steel, Shougang steel, Guanzhou steel, Yieh Phui steel,Xinyu steel,etc.
2)Polyurethane core material: Our polyurethane core material strategic cooperation brands are D·BASF, Huntsman, WANHUA, etc.Properties of polyurethane sandwich panel: Color range: offwhite,silver gray,sea-blue,crimson and so on Insulated core:PU/PIR/PUR Painting:Polyester coating PE,SMP coating,HDP coating,fluorocarbon coating PVDF,ect Galvanzing:Hot-dip zinc coating,hot-dip aluminum-zinc coated Allowable vertical load and heat transfer coefficient of polyurethane sandwich wall panel (allowable defiection f≦L/200) | Thickness (mm) | Heat transfer coefficient (W/m2k) | Weight (kg) | Load (KN/m2) | 0.60 | 0.80 | 1.00 | 1.20 | 1.50 |
