Abstract

The degradation appears obviously earlier in mechanical properties than in dielectric properties for many organic insulating polymers when they are aged under adverse environments. Regarding this, elongation-at-break (EAB), tensile strength (TS), and indenter modulus (IM) were measured for cross-linked polyethylene (XLPE), flame-retardant ethylene-propylene rubber (FR-EPR), cross-linked polyolefin (XLPO), silicone rubber (SiR), and soft epoxy resin (SER). As a result, it has become clear that EAB and IM are respectively good aging indicators in early and late stages of aging of FR-EPR and SiR. For SER, EAB can be a good indicator. In comparison, EAB and TS can be aging indicators of XLPE. However, EAB cannot be a good aging indicator of XLPO.
