要約(日本語): Cobalt 60 gamma rays were irradiated at two different dose rates to sheets of flame-retardant ethylene-propylene-diene rubber (FR-EPR) at room temperature or 100 ℃. After that, saturated or superheated steam was exposed to several sheets at a constant temperature of 155 or 220 ℃, or at elevating temperatures of 120 to 220 ℃. Various mechanical properties and complex permittivity were measured for these sheets. As a result, the effects of heat, gamma irradiation, and steam exposure on the degradation of FR-EPR were clarified.
