Abstract

In this research, new hybrid bio-polyurethane foam was fabricated by reacting with biomass such as lignin, starch and cellulose. Hybrid bio-polyurethane foam was prepared by reacting Toluene Diisocyanate 80 (TDI 80) and Polypropylene Glycol 2000 (PPG 2000), and then the variation of biomass was added to the reaction. Hybrid biopolyurethane foam was characterized its tensile strength, indentation load deflection and airflow. Mechanical properties measurements indicated that the highest tensile strength was obtained polyurethane (PU)-lignin foam meanwhile the highest hardness was obtained PU-cellulose foam. Airflow test showed that PU–cellulose foam has more closed cell than PU-lignin and PU-starch. The morphology of foam was investigated using field emission scanning electron microscopy (FE-SEM). The SEM showed that starch has a smaller pore surface than other biomass. The cell morphology of hybrid biomass based polyurethane foam were closed with some particle stick onto the cell wal
