摘要： A polymer composition may include at least one ethylene vinyl acetate (EVA) polymer; a blowing agent in an amount ranging from 2 to 18 phr; and a crosslinking agent in an amount ranging from 0.3 to 4 phr. A method includes expanding an EVA-based polymer composition to form a foam having a density ranging from 0.01 g/cm3 to 0.06 g/cm3 and a hardness ranging from 10 to 60 Shore 00.
