Abstract
An improved cellular plastic material comprises a urethane foam that is the reaction product of soy oil, an isocyanate, and a cross linker. The soy oil replaces the polyol typically generally required in the production of urethanes. Because the replaced polyol is a petrochemical, use of a renewable and environmentally friendly material such as soy oil is most advantageous. Further, plastic materials of many final qualities may be formed using a single vegetable oil. In addition to cellular foams, solid plastic elastomers may be formed.
