Polyurethane elastomers from polyols based on soybean oil with a different molar ratio
Kamila Mizera , Joanna Ryszkowska
Abstract"The aim of this work was to determination of the influence of different molar mass of used soybean oil (SO)- based polyols on the properties of tested polyurethane elastomers (PUR), with a different content of hard segments (HS). The chemical structure and degree of phase separation of tested materials were characterized via Fourier transform infrared spectroscopy (FTIR). The thermal properties were deter- mined by thermogravimetry (TGA) and differential scanning calorimetry (DSC). The mechanical prop- erties were tested by dynamic mechanical thermal analysis (DMTA) and by static tensile test. Also hardness and wear resistance were carried out. The replacement of the petrochemical polyol by soy- based polyol make changes in chemical constitutions and thermal decomposition of PURs. PURs with SO polyol with lower molar mass had a higher thermal resistance, mechanical and physico-mechanical properties."
