PROBLEM TO BE SOLVED: To solve such a problem that, in a conventional resin molded article, resistance to a snowmelt agent and heat was insufficient in that PA6 is inferior in a snowmelt salt property, and PA11 and PA12 has a defect of low heat resisting temperature despite exhibiting a good snowmelt salt property, etc.SOLUTION: A tube material superior in snowmelt salt resistance comprises 100 pts.wt. of a polyamide resin and 3-40 pts.wt. of an impact resistant material, wherein the polyamide resin comprises 40-99 wt.% of polyamide 66 and 1-60 wt.% of an aromatic polyamide resin. |
