  • Shoe sole comprising a rubber composition based on nitrile-butadiene rubber, an oil and a resin
    Patent number: 9060566
    Abstract: Shoe soles comprising a rubber composition comprising at least: 60 to 100 phr of a nitrile-butadiene rubber; between 10 and 50 phr of a reinforcing filler; a plasticizing system comprising: a hydrocarbon-based resin having a Tg of greater than 20° C.; a plasticizer that is liquid at 20° C., the Tg of which is less than ?20° C.; a crosslinking system, such that the elastomer composition based on a nitrile-butadiene rubber and a mixture of two plasticizers, one liquid plasticizer and one resin, makes it possible to obtain shoe soles having a good grip on various floors, while retaining a good wear resistance and a low hydrocarbon absorption.
