Abstract
Polyurethane foams that are hydrophilic but nonetheless have low compression sets are made from a combination of MDI and TDI prepolymers, water, and a polymer polyol. The foams optionally are made incorporating a phase change material in the foam formulation. The phase change material does not require encapsulation.
