High-Density Polyethylene (HDPE) is a thermoplastic polymer produced from ethylene. Its linear molecular structure, with few branches, provides high density, mechanical strength, and rigidity—ideal characteristics for infrastructure applications.
| Property | Typical value |
|---|---|
| Density | 0.941 – 0.965 g/cm³ |
| Tensile strength | 25 – 45 MPa |
| Operating temperature | -50°C to +60°C |
| Chemical resistance | Acids, bases, solvents |
| Estimated service life | 75+ years |
| Recyclability | 100% |
HDPE offers greater flexibility, impact resistance, and durability in harsh environments. It is chlorine-free, making it more environmentally safe.
Corrosion-resistant, significantly lighter, lower transportation and installation costs, and no need for cathodic protection.
Up to 10 times lighter, flexible (absorbs settlement), quick installation, no rigid joints that crack.
HDPE is 100% recyclable and inert—it does not release toxic substances into the soil or water. Its light weight reduces transportation emissions, and its 75+ year lifespan minimizes the need for replacements.
