HDPE is known for its
 
large strength to density ratio.[2] The mass density of high-density polyethylene can range from 0.93 to 0.97 g/cm3.[3] Although the density of HDPE is only
marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength than LDPE. The
difference in strength exceeds the difference in density, giving HDPE a higher specific strength.[4] It is also harder and more opaque and can withstand somewhat
higher temperatures (120 °C/ 248 °F for short periods, 110 °C /230 °F continuously). High-density polyethylene, unlike polypropylene, cannot withstand normally
required autoclaving conditions. The lack of branching is ensured by an appropriate choice of catalyst (e.g., Ziegler-Natta catalysts) and reaction conditions.
HDPE contains the chemical elements carbon and hydrogen.
