CROSS-LINKED POLYETHYLENIC RESIN PIPE AND METHOD OF MANUFACTURING CROSS-LINKED POLYETHYLENIC RESIN PIPE

摘要

PROBLEM TO BE SOLVED: To provide a cross-linked polyethylenic resin pipe for remarkably improving pressure-proof performance an flexibility, and a manufacturing method of the cross-linked polyethylenic resin pipe. SOLUTION: This cross-linked polyethylenic resin pipe is composed of a cross-linked polyethylenic resin by heating and cross-linking a polyethylenic resin composition having a base resin composed of a polyethylenic resin having 2 to 5 molecular weight distribution, and 0.938 g/cm3 to 0.945 g/cm3 density, and organic peroxide mixed at a rate of 1 pts.wt. to 5 pts.wt. to this base resin of 100 pts.wt. at a melting point or higher of the polyethylene resin.
