Document Type and Number:

WIPO Patent Application WO/1997/028217

Kind Code:

A1

Abstract:

A rubber composition lowered in heat build-up which comprises (a) 100 parts by weight of an elastomer cross-linkable with an organic peroxide cross-linking agent, (b) 10 to 150 parts by weight of a metal salt of an 'alpha','beta'-ethylenically unsaturated carboxylic acid, (c) 5 to 100 parts by weight of magnesium oxide having a specific surface area of 25 m2/g or below as determined by the BET adsorption method, and (d) 0.1 to 30 parts by weight of an organic peroxide cross-linking agent; and rolls having a rubber cover made of a product of cross-linking of the composition. The rolls have both excellent strength characteristics and low heat build-up and are particularly suitable for the use under high load.
