Abstract

Polyurethane is a polymer compound that consists of a hard segment and a soft segment. Further modifications of polyurethane make it possible to make foam products with a variety of properties. Polyurethane foam has a tendency to be rigid and flexible by adjusting the segment ratio and adding chain extenders during the synthesis process. The basic precursors used in this research on bio-polyurethane foam are Polypropylene Glycol 2000, Toluene Diisocyanate 80, Amine catalyst, Tin catalyst, surfactant, and the addition of lignin biomass as a chain extender and as independent variables of this study with 1, 2, and 3 wt% variations with the synthesis method used is a one-shotmethod. In attempt to investigate the effect of lignin chain extender additionto the macromolecular structures and morphology, FTIR and SEM are used,while the mechanical properties are analyzed using tensile machine. From thesynthesis carried out, bio-polyurethane foam with open pore shape isobtained. It has increased tensile strength, but the elongation tends todecrease with increasing lignin biomass addition
