Abstract
A railroad rail track pad composition including a particular ethylene·α-olefin·non-conjugated polyene random copolymer (A), clay (B), and a sulfur atom-containing silane coupling agent (C) is used in order to lower the viscosity of a rubber composition that is a raw material for molding while suppressing lowering of the rubber elasticity of a crosslinked and molded product to be obtained. In addition, a molded product obtained by crosslinking the composition, particularly a molded product obtained by crosslinking and foam-molding the composition, is provided with rubber elasticity that is suitable as a railroad rail track pad.
