WebPolyurethane is a thermosetting material; however, it does soften slightly with increased temperature and hardens somewhat at very low temperatures. Softening at high temperatures affects the polyurethane in two ways: (a) loss of strength properties and (b) change in foam dimensions (particularly low-density foams).
