Engineering Properties of Polyethylene
1 AWWA MANUALM55 Chapter1 Engineering Properties of PolyethyleneINTRODUCTIONA fundamental understanding of material characteristics is an inherent part of thedesign process for any piping system. With such an understanding, the pipingdesigner can use the Properties of the material to design for optimum chapter provides basic information that should assist the reader in understandinghow Polyethylene s (PE s) material characteristics influence its Engineering is a thermoplastic, which means that it is a polymeric material that can be soft-ened and formed into useful shapes by the application of heat and pressure and whichhardens when cooled.
the melt index technique of analysis as described in ASTM D12381. The melt index tech-nique is an inexpensive means of comparing, in a relative manner, the molecular weight of PEs having similar structure.
