| abstract |
The present invention uses a composition for a rail gasket for a railway rail, which is characterized in that the viscosity of the rubber composition belonging to the forming material is lowered to suppress the rubber elasticity of the obtained crosslinked molded body. The ethylene-α-olefin-nonconjugated polyene random copolymer (A), clay (B), and sulfane coupling agent (C) containing a sulfur atom. Moreover, the molded body obtained by cross-linking the composition, in particular, the molded body obtained by cross-linking foam molding, has rubber elasticity suitable as a rail gasket for railway rails. |
