摘要
Provided is a composition for a gas seal member that can form a gas seal member for a high-pressure hydrogen device that is capable of sufficiently inhibiting both swelling destruction and blister destruction. The composition for a gas seal member is a composition for a gas seal member used in a high-pressure hydrogen environment and contains an elastomer and fibrous carbon nanostructures. The fibrous carbon nanostructures are contained in a proportion of not less than 1 part by mass and not more than 10 parts by mass per 100 parts by mass of the elastomer. An area fraction S (%) of aggregates of the fibrous carbon nanostructures in a cross-section of the composition for a gas seal member and a volume percentage V (volume%) of the fibrous carbon nanostructures in the composition for a gas seal member satisfy a relationship 0 ≤ S/V ≤ 2.0.
