Plastic composition, midsole made from the same and method of making
A plastic composition includes a polymer component. The polymer component includes an ethylene-vinyl (EVA) copolymer, a first ethylene-α-olefin copolymer having a hardness ranging from 55 Shore A to 60 Shore A measured according to ASTM D2240, a second ethylene-α-olefin copolymer having a hardness ranging from 85 Shore A to 90 Shore A measured according to ASTM D2240, and polypropylene (PP). The plastic product made from the composition has a loss factor ratio of tan δ(−20° C.) to tan δ(40° C.) at a frequency of 10 Hz, which ranges from 2.5 to 3.8. A midsole and a method of producing the midsole are also disclosed.
