Title:
CROSSLINKABLE RUBBER COMPOSITION FOR CONDUCTIVE ROLLS, RUBBER CROSSLINKED MATERIAL FOR CONDUCTIVE ROLLS, AND CONDUCTIVE ROLL
Document Type and Number:
WIPO Patent Application WO/2014/157045
Kind Code:
A1
Abstract:
Provided is a crosslinkable rubber composition for conductive rolls, which contains a polyether rubber, a solid nitrile rubber, a liquid nitrile rubber, a sulfur-containing crosslinking agent, a disulfide-based crosslinking accelerator, and a conductive carbon black having an average primary particle diameter of 50 nm or less and a BET specific surface area of 600 m2/g or more. The present invention is able to provide a crosslinkable rubber composition for conductive rolls, which is capable of providing a rubber crosslinked material that has low hardness, low volume resistivity and excellent compression set resistance.
