MATERIAU COMPOSITE A BASE DE CAOUTCHOUCS DE TYPE SILICONE ET DE TYPE ETHYLENE-PROPYLENE COPOLYMERE OU TERPOLIMERE.

摘要

Composite material comprising at least two layers of elastomers, the first layer consisting of a first composition containing between 40 % and 80 % by weight of silicone rubber, while the second layer consists of a second composition containing between 50 and 100 % by weight of rubber of ethylene propylene copolymer and/or terpolymer type. According to the invention the first composition also contains between 20 and 60 % by weight of rubber of ethylene propylene copolymer and/or terpolymer type and each of the two compositions contains more than 5 % and, preferably, between 5 and 60 % by weight of silica.
