Abstract

See full text

Disclosed is a method for producing a sealing member for piping materials having excellent chlorine resistance, which includes a first step and a second step. The first step is a step wherein first carbon nanofibers produced by vapor deposition are subjected to an oxidation treatment, thereby obtaining second carbon nanofibers each having an oxidized surface. The second step is a step wherein carbon black having an average particle diameter of from 50 nm to 10 μm and the second carbon nanofibers are mixed into an ethylene-propylene rubber and dispersed in the ethylene-propylene rubber by a shearing force.
