Polyether polyols for rigid polyurethane (PU) foams are low molecular weight (MW) adducts of propylene oxide (PO) [sometimes together with ethylene oxide (EO)] to polyols having 3-8 hydroxyl ...
In contrast to the open cell structure of flexible polyurethane foams, rigid foams have a mainly closed cell structure. They are expanded using physical blowing agents which are retained in the closed ...
