The sorption of argon, carbon dioxide, and nitrogen on two heat shield composites SLA‐561 and SLA‐561V and the SLA components was measured over the pressure range of 10 −3 to 760 torr and in the temperature range of 30° to 50°C. The sorption of the gases by both the composites and the components varied directly with pressure. The sorption of CO 2 by the phenolic spheres and the silicone elastomer and of Ar by the silicone elastomer varied inversely with temperature. The mechanism involved in the gas sorption was primarily absorption.
