Kind Code:
A1
Abstract:
Provided is an automobile cooling system tube formed from a crosslinked body of a polyethylene resin composition that contains component (A) as a main component and that contains component (B). Accordingly, it is possible to realize at low cost both hydrolysis resistance and strength or the like. (A) is a silane grafted polyethylene resin formed by graft polymerization of an ethylenic unsaturated silane compound on a polyethylene resin having been polymerized by a Phillips catalyst. (B) is at least one crosslinking catalyst selected from the group consisting of aluminum crosslinking catalysts, titanium crosslinking catalysts, zirconium crosslinking catalysts.
