What is the density of HDPE?
HDPE is known for its high strength-to-density ratio. The density of HDPE ranges from 930 to 970 kg/m 3. The standard method to test plastic density is ISO 1183 part 2 (gradient columns), alternatively ISO 1183 part 1 ( MVS2PRO density analyzer ). 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 (38 MPa versus 21 MPa) than LDPE. The difference in strength exceeds the difference in density, giving HDPE a higher specific strength. It is also harder and more opaque and can withstand somewhat higher temperatures (120 °C/248 °F for short periods). 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.

What temperature should HDPE pipes be used?
Temperature: For pressure systems, the use of HDPE pipes are usually limited to -40 0 C to 50 0 C. For non-pressure services, higher temperatures can be used. Consult with the manufacturer for getting information about their product. Note that, the co-efficient of linear thermal expansion for HDPE pipes is approximately 10 times higher than that of metal pipes. So, the potential of thermal expansion due to temperature fluctuations is very high and must be considered in the design. A typical Thumb rule is HDPE pipes will expand or contract by 0.2mm per meter per °C increase or decrease in temperature.
