Polyurethanes from plant- and fossil-sourced polyols: Properties of neat polymers and their sisal composites

Polyurethanes are synthesized from polyols, which can be fossil- or plant-sourced. The goal of this study was to investigate how the use of plant-sourced polyols, i.e., the ricinoleic acid triglyceride (the main component of castor oil, CO) and lignosulfonate, impacts the properties of the materials, as well as of their composites reinforced with sisal fibers. To reach this objective, the properties of polyurethanes from plant-sourced polyols...
