摘要： A resin sub-seal member (11) provided with a concave groove (16) is disposed at a region closer to a higher-pressure side region than a rubber main seal member (10) and pressure variation in a gas on a higher-pressure side is inhibited from being transmitted to the main seal member (10). Further, a variation reducing space (13) is formed between the seal members (10) and (11) to be able to reduce the pressure variation when gas leakage in the sub-seal member (11) occurs or the sub-seal member (11) responds with a delay with respect to the pressure variation. Thus, rapid change in the pressure of the gas surrounding the main seal member (10) is inhibited, occurrence of the blistering phenomenon is inhibited, and a high seal ability is achieved. The seal structure is formed by a simple structure including the seal members (10) and (11), and the variation reducing space (13).

摘要： An insulating composition comprising a syndiotactic polypropylene (s-PP) having a syndiotactic pentad ratio of not less than 0.7 and an MFR of 0.05-2.0 g/10 min. The composition of the present invention comprising a specific s-PP can provide an article having superior electric properties and mechanical properties. In particular, the article can retain superior electric properties and mechanical properties even after rapid cooling or gradual cooling for re-processing of said article. Accordingly, the composition of the present invention can be suitable used for insulating layer, coating layer of various power cables inclusive of high voltage wires and low voltage wires, coating layer of optical fibers and insulator of wire-connecting structures.
