RUBBER COMPOSITION USED FOR HIGH-PRESSURE GAS SEALING MEMBERS, AND HIGH-PRESSURE GAS SEALING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a rubber composition used for high-pressure gas sealing members that satisfies excellent wear resistance, low temperature resistance, heat resistance and blister resistance at the same time, and a high-pressure gas sealing member.;SOLUTION: The present invention provides a rubber composition used for high-pressure gas sealing members, which seals a high-pressure gas. Rubber components in the rubber composition comprise polybutadiene and/or polystyrene-butadiene rubber. The rubber composition has a glass transition point of -65°C or less.;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
