RUBBER COMPOSITION

Title:

RUBBER COMPOSITION

Document Type and Number:

WIPO Patent Application WO/2019/188338

Kind Code:

A1

Abstract:

This rubber composition is obtained by blending 0.1-2.5 parts by weight of a lubricant having a flow temperature of 50-100°C relative to 100 parts by weight of an ethylene·butene·5-ethylidene-2-norbornene terpolymer. By containing a specific lubricant, this rubber composition achieves the advantageous effects of preventing sticking between unvulcanized rubber materials, improving productivity in a rubber material preparation step and a vulcanization-molding step of a crosslinked molded article such as a sealing member, and not causing a deterioration in low temperature properties of the crosslinked molded article. This rubber composition is particularly effective as a crosslinking molding material of a sealing component that requires a high-pressure gas sealing function in a low temperature environment such as -39°C or lower.
