Thermal and fire resistant properties of palm kernel oil and soybean oil-based polyurethanes

Thermal and burning properties of palm kernel oil and soybean oil-based polyurethanes were compared. Monoester with hydroxyl end group was prepared by reacting the palm kernel oil (PKO) and the soybean oil (SBO) with polyhydric compound consisting of diethanolamine/ethylene glycol and potassium acet...

Monoester with hydroxyl end group was prepared by reacting the palm kernel oil (PKO) and the soybean oil (SBO) with polyhydric compound consisting of diethanolamine/ethylene glycol and potassium acetate as the catalyst.

SBO-based polyurethane foam had lower entalphy then the PKO-based polyurethane foam with values of 7151 cal g-1 comapred to 7223 cal g-1. Similarly, the TGA analysis indicated that the percentage of weight loss of the former was also lower (91.0%) then the latter (92.3%) with stable temperatures, Tstable at 196 and 198 oC, respectively. The burning rate of the SBO-based polyurethane foam was 0.6-1.2 mm¥s-1, lower then the PKO-based polyurethane foam which was 1.1-1.6 mm s-1. However, the dimensional stability test showed that the shrinkage and expansion values were lesser for the SBO-based polyurethane foam compared to the PKO-based polyurethane.
