As a result of nearly ten year's investigation, a new plastic material of excellent quality for use at cryogenic temperatures has been successfully developed. It is a special kind of ethylene-vinylacetate copolymer foam composed of completely closed cells and impervious to gas or liquid. The mechanical characteristics of this material at minus 196 deg C are as follows: the elongation is some 10%, the breaking strength is nearly seven times the thermal stress, and the compressive proportional limit is more than 15 kg/sq cm. The thermal conductivity is approx. 0.02 kcal/m/h-deg C in the lower temperature range. The stability has been proved by various aging tests such as a longtime dipping test in liquefied methane, both outdoor and indoor exposure tests, and a bending fatigue test at minus 196 deg C. A liquefied nitrogen storage tank in which this materials is applied for the inner vessel wall has been in use for approximately two years with quite satisfactory results. This paper provides mainly the results of the fundamental tests conducted on the newly developed plastic foam.
