Title:
BIODEGRADABLE FOAM COMPOSITION FOR AN INSOLE USING POLYLACTIC ACID, AND METHOD FOR PREPARING SAME
Document Type and Number:
WIPO Patent Application WO/2012/099357
Kind Code:
A2
Abstract:
The present invention relates to a biodegradable foam composition for an insole using polylactic acid and to a method for preparing same in which a large amount of polylactic acid is mixed with a mixing base that includes polylactic acid as a biodegradable resin and a copolymer mixture. Since the mixing base includes a large amount of the polylactic acid as the biodegradable resin, the foam thus obtained may exhibit high biodegradability. In addition, since the copolymer mixture of an ethylene vinyl acetate copolymer, a styrene isoprene styrene copolymer, and an ethylene methyl acrylic acid copolymer are used for preparing the composition, the foam thus obtained may have good durability and high hardness. The foam may be advantageously used as a material for manufacturing an insole.
