Mechanical Properties of Insulating Plastic Foams at Low Temperatures
Expanded plastics have found considerable use as cryogenic insulation in applications where only moderate thermal efficiency is required, especially where it is convenient for the insulation to be self-supporting or to provide support to other structures. The thermal gradient in which they see service, however, induces thermal stresses which can be great enough to cause failure of the insulation structure if the design does not allow for the effects of the characteristically high thermal contraction and relatively low tensile strength of these materials.
