PEX-a Crosslinked Polyethylene Pipes
PEX-a Crosslinked Polyethylene Pipes Production Technology, Performance Advantages, and Standards Compliance 1. Introduction Crosslinked polyethylene, commonly referred to as PEX (or PE-X in European nomenclature), is a thermoset polymer produced by introducing covalent crosslinks between individual polyethylene macromolecular chains. Unlike conventional thermoplastic high-density polyethylene (HDPE), the three-dimensional network structure in PEX prevents the material
