Polyols from recycled poly(ethylene terephthalate) flakes

and rapeseed oil for polyurethane foams (in English)

Polimery 2015, No 9, 572


DOI: dx.doi.org/10.14314/polimery.2015.572

Summary
Bio/recycled polyols from rapeseed oil (RO) and poly(ethylene terephthalate) (PET) were prepared using a continuous, two-step synthesis method. The bio/recycled polyol properties were compared to RO and commercially available PET based polyols. Rigid polyurethane foams with a unified apparent density of 40—45 kg/m3 were prepared from these polyols. The thermal conductivity, thermal properties, water absorption and mechanical properties of foams were tested. The results indicated that the RO/PET polyols can be successfully used for preparing polyurethane foams as energy efficient thermal insulation material.
