The goal of this work is decrosslinking of castor oil based polyurethane foam (CPUF) using an ultrasonic reactor. Three different biomass contents of CPUFs (5, 10, and 20%) were subjected to ultrasonic wave. Gel fraction, crosslink density, and thermal properites of ultrasonically decrosslinked CPUFs were measured. For the recycling, ultrasonically decrosslinked samples were used for synthesis of polyurethane foam up to 5 wt%. Comfort properties of polyurethane seat cushions were investigiated. |
