HDPE's History, Background and Supporting Organizations
High density polyethylene (HDPE) popularity and usage continues to increase. The relationship HDPE products have with our everyday lives is symbiotic, so much so, it is hard to imagine a single day where someone would not encounter HDPE in some form or another. Whether you&#;re drinking water, watching TV, enjoying your warm home, or carrying groceries HDPE is part of each of those activities and countless more.
Since its creation almost 70 years ago, HDPE piping and conduit has become a preferred material for many applications in the construction, power, communications and energy industries and is growing in popularity in municipal and utility use. HDPE conduit is a flexible and versatile product well suited for usage in numerous industrial settings. Specific applications include conduit for telecommunications lines, casing power lines and fiberoptics; flowlines for oil, gas and mining; transmission or &#;cross-country pipelines; and municipal water and sewer lines.
Considering the number of unique HDPE conduit applications and product offerings available to the global market today, many consumers, engineers and designers might not know the HDPE conduit traces its roots from the famous and still popular hula hoop fad from the s. While used for centuries by children and adults alike, the hula hoop craze did not take off until , when mass production from plastic began.
The American Chemical Society article Discovery of Polypropylene and High-Density Polyethylene outlines milestones made along the journey which included Phillips Petroleum researchers Paul Hogan and Robert Banks developing the process for making HDPE in . In Phillips Petroleum commercially introduced HDPE under the brand name Marlex. The company stockpiled Marlex until the hula hoop craze eventually consumed Phillips&#; stockpile of Marlex and plant output for six months.
While numerous refinements and enhancements have been made during the last seven decades, it is worth going back to the original hula hoop design to envision a solution to many of today&#;s piping challenges.
HDPE, by definition
Considered a simple polymer, HPDE is plastic &#;made by the copolymerization of ethylene and a small amount of another hydrocarbon. The resulting base resin density, before additives or pigments, is greater than 0.941 g/cm.&#; (source: Plastics Pipe Institute). At the molecular level, low density polyethylene (LDPE) has many branches while HDPE is linear with very little branching. The branched LDPE is cheaper to produce and considerably more flexible. HDPE&#;s strength, durability and flexibility are a result of its linear molecular structure. HDPE resin is used to make different products, including piping, which is made through an extrusion process.
HDPE pipe has a service life of between 50 and 100 years. Fully recyclable and lighter in weight, HDPE is much stronger than conventional pipe. HDPE heat-fused joints are as strong as metal pipe, or stronger, and do not leak. HDPE pipe offers unmatched corrosion and chemical resistance as it will not corrode (rust), tuberculate or support biological growth. By comparison, HDPE piping is also lighter than alternative piping options.
