Abstract
"The purpose of the study is to manufacture soy hull augmented polyurethane foams and study the physical and mechanical properties for their possible commercial applications. The ratio of soy hulls substituting polyol in the polyurethane foam formulation is 10%, 20% and 30% of 100 parts polyol. Soy hull augmented polyurethane foams are compared with control foam -- pure polyurethane foam, for the density, compressive strength, tensile strength and hardness.
Various commercial methods and formulations are available for manufacturing polyurethane foams. In this study, a standard laboratory method is used to acquire a small amount of polyurethane foam with commercial quality. The density, compressive strength, tensile strength and hardness of polyurethane foams are obtained through standard ASTM tests. From the comparison results of the soy hull augmented polyurethane foam with pure polyurethane foam, it is concluded that, density increases with higher percentage of soy hull substitution and, soy hull augmented polyurethane foams have improved mechanical properties over pure polyurethane foam"--Abstract, page iii.
