Book Description

Details and results of a literature search and study of thermal insulating materials for use at elevated pressures in atmospheres suitable for breathing are presented herein. Sufficient theory and data were found to permit determination of heat loss data of some insulating materials, assuming all the gas within the insulation was replaced by the breathing gas mixture. The accuracy of the theoretical values, the degree to which the gas mixture permeates the insulation, and the significance of the gas pressure in the permeation process remain to be determined experimentally.
