HDPE
High-density polyethylene for bottles, pipes and rigid packaging.
High-density polyethylene (HDPE) is the base material for bottles, jerrycans, pipes and rigid packaging thanks to its stiffness, impact and chemical resistance. Blow-moulding, injection and extrusion grades are supplied separately.
Typical Technical Properties
- Density
- 0.94–0.97 g/cm³
- MFI (190 °C / 2.16 kg)
- 0.03 – 30 g/10 min (grade dependent)
- Melting point
- 125–135 °C
- Grades
- Blow moulding, injection, pipe (PE80/PE100), film
- Packaging
- 25 kg bags, big bags
Values are typical industry ranges; the producer's lot-specific TDS/MSDS is binding.
Applications
- Milk, detergent and chemical bottles
- Jerrycans and drums
- Pressure water and gas pipes (PE100)
- Crates, pallets and containers
- Industrial bag film
Frequently Asked Questions
What is PE100?
An HDPE grade classified for pressure pipe; it means a minimum required strength of 10 MPa for a 50-year lifetime. Used in water and natural gas lines.
What is the difference between blow and injection grades?
Blow grades provide melt strength with low MFI; injection grades fill the mould quickly with high MFI. Choosing the wrong grade leads to production defects.
