An improved cellular 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.

Une matière plastique alvéolaire améliorée comprend une mousse d'uréthane qui est le produit de réaction d'huile de soja, d'un isocyanate et d'un agent de réticulation. L'huile de soja remplace le polyol qui est en général spécifiquement utilisé dans la production des uréthanes. Etant donné que le polyol remplacé est un produit pétrochimique, l'utilisation d'une matière renouvelable et respectueuse de l'environnement telle que l'huile de soja est extrêmement intéressante. En outre, les matières plastiques possédant plusieurs qualités finales peuvent être formées à l'aide d'une seule huile végétale. Hormis les mousses alvéolaires il est possible de former des élastomères plastiques solides.
