Tensile Properties of Polyurethane and Polystyrene Foams from 76 to 300 K
Polyurethane and polystyrene foams are currently used in cryogenic applications as an insulating material. Since a large percentage of their volume is air (or whatever gas was used as the expanding agent in their manufacture) their thermal conductivity is very low. Increasingly, foam use in such applications requires load-carrying capacity. For efficient design in these cases mechanical property information is needed. Unfortunately, relatively few low-temperature mechanical property data have been generated [1–5].
