An investigation was made of the influence of the quantity of the main and auxiliary components of the base polyurethane foam composite individually on the glass transition temperature and open porosity of rigid polyester urethane foam, the shape memory effect in which was investigated under conditions of microgravitation aboard the International Space Station. It was established that the glass transition temperature can be controlled in the widest range by varying the content of polyisocyanate and catalyst with chain extender, and the open porosity by varying the content of cell destroyer, surfactant, and catalyst with chain extender.
