Abstract

In the formulation of biobased foam from Ximenia americana seed oil polyol, The tensile, mechanical and other physical properties of the biobased polyurethane (PU) foams with various concentrations of water from (0.04 to 1.8 ml) were characterized using physi-mechanical evaluations. These physical propteies incate that water level has various effect on the microstructures of biobased foam and affects the physical and mechanical properties of the biobased foam. These occurred because water is responsible for formation of gas in the isocyanate/polyol reaction it aids in the chain extension process of polyurethane resin. A decrease in the density and other mechanical properties occurred as water level increased from (0.04 to 1.8 ml), while the gel time cream time increased as the concentration of water increased. A low density biobased at (1.6 ml) concentration of water with good performance was prepared by optimizing the process.
