Integral-skin foam: Urethane foams that are formed with integral skins range from soft and flexible types to impact-absorbing grades and rigid foams used in structural parts. Color can be added, but since the foams yellow on aging, black is most practical

and bases. High creep resistance and low-moisture absorption give the polyesters excellent dimensional stability. Equilibrium water absorption, after prolonged immersion at 73° F, ranges from 0.25 to 0.50% and, at 150°F, is 0.52 to 0.60%. Black-pigmented grades are recommended for maximum strength retention
