WIPO Patent Application WO/2023/188568
Kind Code:
A1
Abstract:
The present invention provides a resin composition which has excellent flexibility, water vapor barrier properties and heat resistance. The present invention provides a resin composition which contains a silane-modified resin and an elastomer that has a polyisobutylene skeleton, and which is characterized in that: the content of the elastomer that has a polyisobutylene skeleton based on the mass of the resin composition is 30% by mass to 90% by mass; the content of the silane-modified resin based on the mass of the resin composition is 10% by mass to 70% by mass; the water vapor transmission rate of the resin composition is 2.0 g∙mm/(m2∙24 h) or less; and the ratio TB100/TB25 of the strength at break TB100 of the resin composition at 100°C to the strength at break TB25 of the resin composition at 25°C is 0.2 to 1.0.
