Abstract

See full text

The present disclosure provides a high-pressure hydrogen apparatus gas seal member which is excellent in durability and is capable of sufficiently suppressing an occurrence of a blister fracture. A high-pressure hydrogen apparatus gas seal member of the present disclosure is a high-pressure hydrogen apparatus gas seal member made of a crosslinked product of an elastomer composition which comprises an elastomer and fibrous carbon nanostructures having an average length of 100 μm or more and 1000 μm or less, wherein the fibrous carbon nanostructures have a surface fractal dimension of 2.3 or more and 3.0 or less or a radius of gyration of 50 nm or more and 500 nm or less, and further the fibrous carbon nanostructures has an inner diameter of 4.0 nm or less.
