With a worldwide consumption of around 40 million metric tonnes per year, HDPE is one of today's major thermoplastics and the most widely used type of polyethylene (PE). HDPE resins include ethylene homopolymers as well as copolymers of ethylene and alpha-olefin monomers such as 1-butene, 1-hexene and 1-octene. HDPE has higher crystallinity (density) compared to low density polyethylene (LDPE) and linear low density polyethylene (LLDPE), which results in higher mechanical properties such as stiffness, modulus and tensile strength, higher temperature resistance, improved barrier properties as well as improved chemical resistance to a variety of solvents and chemicals. HDPE properties can be adjusted by controlling the molecular weight, molecular weight distribution, degree and type of short chain branching and amount of long chain branching to design resins with optimum performance for different end-use applications. HDPE is used worldwide in a very large variety of applications such as rigid containers, toys, film products, sheet products, injection-molded articles, pressure and non-pressure pipes, geomembranes, automotive parts and fuel tanks, to name just a few. In Qatar, HDPE is produced by Q-Chem and Q-Chem II. Q-Chem and Q-Chem II have a range of HDPE products focused on blow molding, film, geomembrane and pipe application segments. Selected examples of specific end-use applications are: dairy bottles, containers for household chemicals, large blow-molded drums, industrial liners, bags and packaging film, geomembranes, pond liners, and pipes and fittings.
