Abstract
An elastomeric laminate is provided. The elastomeric laminate comprises a layer A consisting of a diene rubber composition, a layer B comprising a highly unsaturated diene elastomer B, n layers Ci arranged between the layer A and the layer B, n being an integer ≥2, i being an integer ranging from 1 to n, the layer C1 being arranged between the layer A and the layer C2, the layer Cn being arranged between the layer B and the layer Cn−1, the layer Ci being arranged between the layer Ci−1 and the layer Ci+1 for values of i ranging from 2 to n−1 when n>2. Such a laminate has good resistance to separation of the layers which constitute it.
