Title:

COMPOSITION FOR TRACK PAD FOR RAILROAD RAILS, AND TRACK PAD FOR RAILROAD RAILS

Document Type and Number:

WIPO Patent Application WO/2016/152571

Kind Code:

A1

Abstract:

In order to lower the viscosity of a molding-material rubber composition while the crosslinked molded object to be obtained therefrom is being inhibited from having reduced rubber elasticity, use is made of a composition for track pads for railroad rails which is characterized by comprising a specific ethylene/α-olefin/unconjugated polyene random copolymer (A), clay (B), and a sulfur-atom-containing silane coupling agent (C). The molded object obtained from the composition by crosslinking, especially by crosslinking foam molding, has rubber elasticity suitable for track pads for railroad rails.
