- Nowadays, due to economical and environmental concerns, polyurethane (PU) elastomer and rigid foam industry seeks ways to replace petrochemical polyols by renewable biomass. The aim of this study was to investigate lignin as a co-polyol in a solvent free production of castor oil based PU elastomers and tall oil amide based rigid PU foams. Lignin content correlation influence on PU elastomers and PU rigid foam physical-mechanical and morphological parameters were determinate.
