Influence of Palm Oil-Based Polyol on the Properties of Flexible Polyurethane Foams

摘要

This paper describes the effect of the modification of polyurethane system with palm oil-based polyol on the cell structure and physical-mechanical properties of polyurethane foams. Flexible polyurethane foams were prepared by substituting a part of petrochemical polyether-polyol with the palm oil polyol. Selected physical-mechanical properties of these foams were examined and compared to the properties of reference foam. The properties such as apparent density, tensile strength, elongation at break, resilience, com-pressive stress and thermal stability were analyzed. It was found that the modifications of polyurethane formulation with palm oil polyol allow to improve selected properties of final products.
