| 摘要 |
The present invention relates to a polyketone resin composition which can be used as materials of a hydrogen tank liner for vehicles and is produced by injection-molding a polyketone polymer having hydrogen permeability of less than 0.1 cc·mm/m^2·atm·day at 23°C and 60% RH conditions. The hydrogen tank liner for vehicles has improved gas barrier properties, impact strength, heat resistance, and wear resistance. |
