A polyurethane foam created from a formulation comprising from about 1
percent to about 70 percent of a vegetable oil polyol is disclosed. The
polyurethane foam is made from a formulation comprising an isocyanate, a
surfactant, and a polyol blend comprising a vegetable oil polyol. Also
disclosed is a polyurethane foam made from a formulation comprising a
polyol blend comprising a petrochemical polyol and a vegetable oil
polyol, and an isocyanate blend comprising a 2, 4 toluene diisocyanate
(TDI) isomer and a 2, 6 TDI isomer, wherein the ratio of petrochemical
polyol to vegetable oil polyol in the polyol blend is about equal to the
ratio of the 2, 4 TDI isomer to the 2, 6 TDI isomer in the isocyanate
blend.
