An elastomeric composition comprising at least one elastomeric polymer and at least one long-chain olefin, wherein said at least one long-chain olefin has a number average molecular weight from 180 g/mol to 2000 g/mol, preferably from 300 g/mol to 1500 g/mol, and consists of at least 40% by weight of at least one linear-chain olefin. Said long-chain olefin is particularly effective, alone or mixed with a wax, against the degrading action of elastomeric material caused by atmospheric ozone. In fact, it is able to migrate to the surface in a controlled and gradual manner, so that the protective effect is guaranteed for a long time without causing undesired blooming effects.
