Rubber base products, methods of manufacturing rubber base products and methods of reducing rolling resistance of tires made of rubber base products.

摘要

The invention concerns a rubber based product, comprising at least one buffer zone for trapping oxygen external to said product so as to protect from oxidation at least one sensitive zone of said product, said or each buffer zone containing a composition based on at least one elastomer comprising at least one iron (III) salt for activating oxidation in said composition. The invention is characterised in that said salt belongs to the group consisting of iron (III) acetylacetonate and carboxylic acids iron (III) salts corresponding to the formula: Fe(CnH2nO2)3 in which n ranges between 6 and 23. Said product is obtained by incorporating by mechanical work said salt in the elastomer or elastomers contained in said composition, for said buffer zone. The invention is particularly useful in a tyre cover providing improved rolling resistance.
