Flexible Polyurethane Foam Extended with Corn Starch

The use of polyurethane foam is continuing to grow at a rapid pace throughout the world. This growth can be attributed to their light weight, excellent strength/weight ratio, energy absorbing performance (including shock, vibration, and sound), and comfort features of the polyurethane foams (Klempner and Frisch, 1991). Recently, there has been an increased interest in the use of renewable resources in the plastics industry (Bhatnagar et al, 1993; Carraher and Sperling, 1981; Cunningham and Carr, 1990; Cunningham et al, 1991, 1992a, and 1992b; Donnelly et al, 1991; Yoshida et al, 1987 and 1990). In addition, many patents covering processes for utilizing the plant components in the preparation of polyurethane foam have been issued in recent years (Dosmann and Steel, 1961; Hostettler, 1979; Kennedy, 1985; Otey et al, 1968). However, most of these studies focused on rigid polyurethane foam. Less attention has been paid to the flexible polyurethane foam system. Corn starch is a renewable raw material. As a carbohydrate, it contains many active hydrogens and hydroxyl groups. Thus, a great opportunity exists for using corn starch to modify or improve the physical and chemical properties of flexible polyurethane foams.
