Abstract This article describes the effects of the modifi cation of polyurethane system with rapeseed oil-based polyol
on the cell structure and physical-mechanical properties of conventional fl exible polyurethane foams.
The foams were prepared by substituting a part of the petrochemical polyether-polyols mixture with the
bio-polyol based on rapeseed oil. Selected physical-mechanical properties of these foams were examined and
compared to the properties of reference foam. The properties such as apparent density, resilience, comfort
factor and stress-strain characteristics were analyzed in compression tests. It was found that the modifi cation
of polyurethane formulation with rapeseed oil-based polyol improves the selected properties… More >
