HYDROGEN TANK LINER MATERIAL AND HYDROGEN TANK LINER

摘要

A hydrogen tank liner material comprises a polyamide resin composition which comprises (A) a polyamide resin at 85-40 wt %, (B) a copolyamide at 5-30 wt % and (C) an impact-resistant material at 10-30 wt % with respect to the total weight of the polyamide resin composition. Preferably, the (B) copolyamide is PA6/66 and the (C) impact-resistant material is an acid-modified ethylene/alpha-olefin-based copolymer. A hydrogen tank liner material with excellent gas barrier properties and superior impact resistance even at low temperatures is obtained.
