Ethylene Propylene Copolymer Compounds for Use in Layered Articles

An article comprising:

• a multilayer structure with at least one layer comprising an ethylene propylene diene copolymer compound that comprises:
• 60 parts per hundred rubber (phr) to 95 phr of a first ethylene propylene diene copolymer having an ethylene content of 62 wt % to 90 wt % based on the first ethylene propylene diene copolymer and a heat of fusion (Hf) of 15 J/g or greater;
• 5 phr to 40 phr of an second ethylene propylene diene copolymer having an ethylene content of 40 wt % to 60 wt % based on the second ethylene propylene diene copolymer and a heat of fusion (Hf) of 0 J/g to 14 J/g,
• wherein the Hf of the first ethylene propylene diene copolymer minus the Hf of the second ethylene propylene diene copolymer is 5 J/g or greater;
• wherein the first ethylene propylene diene copolymer and second ethylene propylene diene copolymer combined are 100 parts;
• a filler at 40 phr to 500 phr;
• and
• a curing agent at 0.5 phr to 20 phr.
