Bio-based Polyurethane Foam Made from Compatible Blends of Vegetable-Oil-based Polyol and Petroleum-based Polyol

The Hansen solubility of two polyols, soy-castor oil based polyol and petroleum-based polyol, were measured to determine their use in polyurethane blends. The two polyols were determined to be miscible over a temperature range of 25 – 90˚C. Multiple ratio blends were tested to prepare the polyurethane foams. It was determined that with an increase in polyol content, the density of the open cell foams was increased. Also, as the bio-content increased, ...
