Abstract
Polyethylene terephthalate (PET) was depolymerized using trimethylolpropane (TMP) and glycerin as a binary solvent mixture to provide oligomeric polyol for rigid polyurethanes foam formulation. Recyclate containing rigid polyurethane foam nanocomposites were prepared by introducing of different portions (1-5%) of nanoclays namely, NaMMT, 30B, 20A, 15A Cloisites. The parallel effects of recycled polyol and nano clays on mechanical and thermal characteristics of the nanocomposites were investigated. Dispersion of clay nano particles in polymer matrix was characterized by SEM what confirm the exfoliation of nanoparticles. The thermal properties were also studied by TMA and DMA.
