Abstract (en)
[origin: WO2019110924A1] The present invention relates to an elastomeric laminate comprising 3 layers, the first layer consisting of a rubber composition comprising a diene elastomer, more than 75 mol % of the constituent repeating units of which are hydrocarbon units, the second layer consisting of a rubber composition comprising a highly saturated diene elastomer which has more than 50 mol % of randomly distributed ethylene units in the elastomer, the third layer consisting of a rubber composition comprising a polar elastomer that comprises ethylene units and vinyl acetate units, the second layer being disposed between the first layer and the third layer. The elastomeric laminate has good resistance to the separation of the layers constituting same.
