Elaboration and Properties of Innovative Biobased PUIR Foams from Microalgae

Original Paper


Foams were elaborated from biobased epoxides and polyols derived from highly unsaturated oil of microalgae (schizochytrium sp.). The same types of chemicals were also synthesized from rapeseed oil, and used as references. Triglycerides derivatives were characterized by IR, titration, NMR and SEC analysis. Epoxidation reaction led to fully epoxidized oils, from both bioresources. These epoxidized oils were transformed in polyols via epoxide ring opening reaction with methanol. A preliminary study was focused on the elaboration of urethane-modified isocyanurate (PUIR) foams to evaluate the reactivity and effect of the previously synthesized derivatives (epoxides and polyols) with isocyanates. These derivatives were used to partially substitute oxypropylated glycerol (OPG), a conventional reference polyol. All elaborated foams were close to the PUIR reference (only based on OPG), in terms of kinetics and morphology. PUIR thermal stability was improved, using directly epoxides derivatives.
