Rigid polyurethane foam-based palm oil polyol/polyepropylene glycol blend

A mixture of palm oil polyol (POP)-polyethylene glycol (PEG) was prepared by mixing POP with either PEG600 or PEG1000 at 1.5:1 wt% ratio. The mixture was then reacted with polymeric 4, 4-diphenylmethane diisocyanate (p-MDI) to form rigid polyurethane foam (PU). Effects of POP-PEG blend on thermal st...
