The use of 100% palm oil polyol without the addition of a chain extender produced foam which initially expands and then collapses so that the resulting foam has tight pores, dense texture, and brittle (brittle). It was necessary to use a chain extender to improve the flexible properties of the foam. This study aimed to examine the ratio of palm oil polyols with a chain extender to produce flexible polyurethane foam with good characteristics. The treatment of this study was a combination of types and comparisons of palm oil polyols with chain extenders which were carried out 3 times, consisting of factor A = type of chain extender (diethylene glycol (DEG), diethanolamine (DEA), and polyethylene glycol (PEG)-400) and factor B = ratio of palm oil polyols. with a chain extender (80%:20%; 70%:30%; 60%:40%; 50%:50%). The obtained foam was observed visually, foam development, and foam density. The best sample for each type of extender was analyzed by FTIR. The results showed that 40% PEG-400 has succeeded in producing flexible polyurethane foam with higher expansion (291.22%), lower density (29 kg/m3), and visually has the best flexible properties. Based on FTIR analysis, the use of PEG-400 in the polyol system can increase the reactivity of palm oil polyols to isocyanates.

Palm oil polyol-based foams have inflexible and brittle properties. Palm oil polyols have a lower molecular weight. Polyols with a high molecular weight and a primary OH group, such as polyethylene glycol (PEG)-400, can provide the flexible properties of polyurethane foam. This study aimed to examine the optimum concentration of PEG-400, which can produce flexible polyurethane foam made from palm oil polyols with the best characteristics based on mechanical properties. This study compared palm oil polyol and PEG-400 treatment of 80%:20%, 70%:30%, 60%:40%, 50%:50%. Flexible polyurethane foam was characterized, including FTIR analysis, SEM, tensile strength, yield strength, elongation at break, and TGA. The results showed that the use of PEG-400 at an optimum concentration of 40% resulted in flexible polyurethane foam with a greater number of open cells and increased flexible properties but decreased the value of tensile strength and yield strength, as well as decreased the foam’s stability to heat. However, tensile strength and elongation at break of PEG-based palm oil polyurethane obtained from this study followed the flexible polyurethane foam requirements.
