Abstract
Provided are a composition having excellent gas barrier property and low-temperature impact resistance, and a liner for high-pressure gas storage tanks including the same. Particularly, provided are a composition, in which resin particles reinforcing low-temperature impact resistance are dispersed in a gas barrier resin, thereby having excellent gas barrier property and excellent impact resistance while being easily moldable, and a liner for high-pressure gas storage tanks.
Claims11
