ABSTRACT:
A method for producing a bio-based polymeric shoe component includes: preparing a blend from a composition including 5˜50 weight parts of a modified starch, 50˜95 weight parts of an ethylene vinyl acetate copolymer, 5˜30 weight parts of a filler, 1˜50 weight parts of a polyolefin, 2.0˜8.0 weight parts of a foaming agent, 0.5˜3.0 weight parts of a foaming aid, 0.5˜2.0 weight parts of a lubricant, and 0.4˜1.2 weight parts of a crosslinking agent, the modified starch being obtained by hydrolyzing and esterifying a predetermined amount of a raw starch to form a hydrolyzed and esterified starch, followed by drying the hydrolyzed and esterified starch; processing the blend into a foamable product; and forming the foamable product into the shoe component.
