Physical and mechanical properties of four types of light-absorbing coating materials were investigated comprehensively under the conditions closely approximating those of the outer space. The physico-chemical processes occurring in irradiated materials are shown to depend on the radiation type as well as on the radiation energy and dose, the structural and chemical composition of the polymer. Based on the experimental results, the Kapton is proposed as a base for the light-absorbing coatings as well as for other composites intended for use in the outer space. In addition to its maximum resistance to radiation, it features plasticity at 4.2 К in contrast with other polymer materials. The Kapton plasticity is supposed to be of quantum nature at Т = 4.2 К
