1. A thermoplastic elastomer composition, comprising
about 80 parts by weight of an ethylene propylene diene monomer (EPDM) including 5-ethylidene-2-norbornene (ENB) and polyethylene,
about 31 parts by weight to about 35 parts by weight of polypropylene,
about 20 parts by weight to about 40 parts by weight of a filler, and
about 60 parts by weight to about 90 parts by weight of a plasticizer,
wherein the ethylene propylene diene monomer has a crystallinity of about 0% to about 15.8%, a crosslinking density of about 2.26×10−4 mol/ml to about 2.68×10−4 mol/ml, and a molecular weight distribution of about 3.4 to about 4.3, and
wherein the polypropylene has a crystallinity of about 52% to about 60%.
