摘要：
The invention concerns a rubber-based product, comprising at least a buffer zone for trapping oxygen outside said product so as to protect from oxidation at least a sensitive zone of said product, said or each buffer zone containing a composition based on at least an elastomer comprising at least an iron (III) salt designed to activate oxidation in said composition. The invention is characterised in that said salt is an iron (III) salt of a carboxylic acid of formula CnH2nO2, wherein n ranges from 2 to 5. Said product is obtained by incorporating by mechanical process said salt in said elastomer or elastomers contained in said composition, for said buffer zone. The invention is advantageously used in a tyre outer casing and provides improved rolling resistance.
