Effect of the Addition of Biobased Polyols on the Thermal Stability and Flame Retardancy of Polyurethane and Poly(urea)urethane Elastomers.

摘要: Due to the current trends in sustainable development and reduction use of fossil fuels (Green Deal strategy circular economy), thus, increased interest polyurethane industry polyols derived from renewable sources, it is important study impact these on flammability new bioelastomers. The goal this was check influence biobased polyols, such as tall oil (TO)-based soybean (SO)-based polyol, rapeseed (RO)-based burning fume emissions poly(urea)urethane elastomers (EPURs EPUURs). thermal stability materials tested using thermogravimetric analysis (TGA). In turn, flame retardancy smoke were checked a cone calorimetry test. released gases identified TGA coupled with Fourier transform infrared (FT-IR) spectroscopy (TGA/FT-IR). Moreover, morphological structural characteristics char residues characterized FT-IR scanning electron microscopy (SEM) energy-dispersive (EDS). obtained data compared results received for produced petroleum substrates. addition led result formation char, especially RO polyol. TO elastomers.
