Title:
COMPOSITION FOR HIGH-FREQUENCY ADHESIVE SHEET FOR FOOTWEAR
Document Type and Number:
WIPO Patent Application WO/2017/135482
Kind Code:
A1
Abstract:
The purpose of the present invention is to propose a composition for improving the physical properties of a TPU high-frequency adhesive sheet to be attached to shoe uppers and, preferably, to improve a TPU high-frequency adhesive sheet that is problematic in that a high-frequency cutting operation is difficult due to the high physical properties and toughness of TPU itself, and when the physical properties are lowered in order to solve such a problem, heat resistance is also lowered therewith and thus deformation may occur in the TPU sheet during the post-processing thereof. To this end, the present invention provides a composition for a high-frequency adhesive sheet for footwear that allows a TPU high-frequency adhesive sheet to have excellent cuttability and also have improved heat resistance, wherein the TPU high-frequency adhesive sheet is manufactured by compounding an ethylene vinyl alcohol copolymer (EVOH) resin with a TPU composition and then extruding the same by a conventional T-die extrusion method.
