Water-crosslinkable polyolefin piping for weather-resistant crosslinked polyolefin piping.

摘要

Water-crosslinkable polyolefin piping obtained by molding a resin composition comprising (A) a water-crosslinkable polyolefin and (B) an ethylene copolymer comprising an ethylene unit and a hindered amine-containing vinyl compound unit and having a melt flow rate of from 0.1 to 200 g/10 min, the vinyl compound unit being present in an amount of from 0.05 to 5% by weight based on the resin composition. The piping, when water-crosslinked, provides crosslinked polyolefin piping excellent in weather resistance and useful for outdoor use.
