HDPE – High Density Polyethylene
HDPE (High-Density Polyethylene) is a stiffer and stronger variant of polyethylene. Due to its high strength-to-weight ratio, excellent chemical resistance, and long service life, it is used for piping systems, tanks, transport packaging, and technical parts.
Advantages
- High strength
- Very good chemical resistance
- Low water absorption
- Good wear resistance
- Low cost
- Excellent weldability
- Good dimensional stability
- Long service life
Disadvantages
- Poorer transparency
- UV sensitivity without stabilization
- Lower heat resistance than engineering plastics
- More difficult to paint
