WebHigh-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. … WebMay 31, 2024 · Prior to the adoption of international standards (CEN, ISO) PE pipe materials were more commonly designated by their density within the range associated with PE i.e. Low Density PE (LDPE), Medium Density PE (MDPE) and High Density PE ( HDPE ). The reference to density gave an indication of the material strength.
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. WebStandard dimension ratio (SDR) is a method of rating a pipe's durability against pressure.
