Abstract
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.
