Research on sealant materials used on the Ariane 4 and 5 launchers is described. Chemical resistance to rocket fuels over the course of periods as long as a month and a half (in the case of delayed launching) is studied. Resistance to combustion products, pressure and relaxation are tested. Thermal stability of the seals is investigated. The types of sealant materials chosen, both elastomeric and plastic, are presented. The quality control policies used in evaluating the seals are described.
