THERMOPLASTIC ELASTOMER COMPOSITION AND DOUBLE GLAZING USING THE SAME COMPOSITION

摘要

PROBLEM TO BE SOLVED: To obtain a thermoplastic elastomer composition excellent in water vapor transmission and heat distortion resistances and to provide a simply producible double glazing using the composition as a sealing material and a spacer and excellent in moisture permeation resistance without shifting the glass plates even at a high temperature. SOLUTION: This thermoplastic elastomer composition is obtained by using a thermoplastic resin having <=100 g/m2.24 h water vapor transmission rate (30μm thickness) and a rubber providing <=300 g/m2.24 h water vapor transmission rate (30μm thickness) when crosslinked as raw materials and has a dispersed phase comprising an at least partially dynamically crosslinked rubber composition in a continuous phase of the thermoplastic resin.
