ELASTOMER LAMINATE

An elastomer laminate comprises at least two adjacent layers, the first layer consisting of a composition based on 20 to 100 phr of at least one copolymer comprising ethylene units and units of a formula CH2═CR-CH═CH2, the ethylene units in the copolymer representing more than 50 mol % of the monome...

Beschreibung
Zusammenfassung:	An elastomer laminate comprises at least two adjacent layers, the first layer consisting of a composition based on 20 to 100 phr of at least one copolymer comprising ethylene units and units of a formula CH2═CR-CH═CH2, the ethylene units in the copolymer representing more than 50 mol % of the monomer units, R representing a hydrocarbon chain having 3 to 20 carbon atoms, 0 to 80 phr of at least one diene elastomer having a weight content of diene units of greater than 50%, 10 to 100 phr of a plasticizing system comprising at least one plasticizing resin having a glass transition temperature above 20° C. and/or at least one plasticizer that is liquid at 23° C., a reinforcing filler, and a crosslinking system, and the second layer consisting of a composition based on a diene elastomer having a weight content of diene units of greater than 50% and a crosslinking system.
