More Information
Summary:The present invention relates to a rubber composition having high rigidity, without the use of large amounts of reinforcing filler or without the use of reinforcing resins, while having improved limit properties. The composition is based on at least one elastomer matrix containing more than 50 phr of at least one copolymer containing ethylene units and diene units, 0 to 50 phr of reinforcing filler, at least 3 phr of a polyethylene, and a crosslinking system.
