Rigid polyurethane foam from glycolysed polyethylene terephthalate dissolved in palm-based polyol

An investigation on the thermal and mechanical properties of rigid polyurethane (PU) foam from polyethylene terephthalate (PET) waste (of plastic drinking bottles) was conducted. The PET waste was glycolysed with ethylene glycol prior to blending with palm based-polyol (PKO-p). This blend was then r...
