Patent ID: 8431651

Claim:
An elastomer composition consisting essentially of a very low density ethylene polymer component and a propylene polymer component, said composition having at least two phases, a very low density ethylene polymer phase and a propylene polymer phase wherein a) the very low density ethylene polymer component has a density equal to or less than 0.89 g/cc and is present in an amount of from 65 to 80 parts by weight and b) the propylene polymer component comprises at least one branched polypropylene and is present in an amount of from 20 to 35 parts by weight, wherein the very low density ethylene polymer phase is continuous, the melt tan delta ratio between the very low density ethylene polymer component and the propylene polymer component is from 0.5 to 4 as measured by parallel plate rheometer at 0.1 radians per second, 180° C., and 10 percent strain, and parts by weight are based on the total combined weight of the very low density ethylene polymer and propylene polymer components.
