Abstract
A power transmission belt having elastomer teeth based on an ethylene alpha-olefin elastomer, provided with an external film, is provided in which the external film is based on a thermoplastic olefin, the thermoplastic of the film being associated with a silicone elastomer that represents at least 20% by weight of the total weight of the film and with a compatibilizing element that ensures, within the film, compatibility between the thermoplastic and the silicone elastomer.
