High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. With a high strength-to-density ratio, HDPE is used in the production of plastic bottles, corrosion-resistant piping, geomembranes and plastic lumber. HDPE is commonly recycled, and has the number "2" as its resin identification code. WebFeb 9, 2008 · Some earlier grades of HDPE had problems when regrind was used. The problem is that the anti oxidant used in the extrusion process was damaged during the first extrusion to the point where when re extruded caused faults. To overcome this the other grades of PE were developed. You can always specify virgin PE for your pipeline.
