Abstract
The present invention relates to a rubber-based product, having at least one buffer zone to trap oxygen external to said product in order to protect at least one sensitive zone of said product from oxidation, said buffer zone comprising a composition containing at least one elastomer and at least one iron (III) salt selected from iron (III) acetylacetonate and an iron (III) salt of a carboxylic acid having the formulaFe(CnH2nO2)3 in which n is between 13 and 23.This product is produced by incorporating, by mechanical working, said iron (III) salt into the composition in order to obtain said buffer zone. The buffer zone composition is advantageously used in a tire and imparts improved rolling resistance.
