What is HDPE?

High density polyethylene (HDPE) is a thermoplastic polymer derived from petroleum.

Unlike low-density polyethylene (LDPE), the molecular chains of HDPE have few ramifications: the result is greater resistance to attraction and greater intermolecular strength than the less dense polyethylene variety, which translates into greater material-specific strength.

HDPE finds many applications whether applied alone or in fusion with other materials.

Its main characteristics are:

  1. Excellent thermal and chemical resistance.
  2. Very good resistance to impact.
  3. It is solid, colorless, translucent, almost opaque.
  4. Very good processability, that is, it can be processed by the forming methods used for thermoplastics, such as injection and extrusion.
  5. It is flexible, even at low temperatures.
  6. It is tough.
  7. It is more rigid than low density polyethylene.
  8. It is difficult to print, paint or glue onto.
  9. It is very light.
  10. Its density is around 0.940 - 0.970 g/cm3.
  11. It is not attacked by acids, it is considered a maximum resistance of 60°C of work for the liquids, because at higher temperature the useful life is reduced. Other thermoplastics offer better resistance at higher temperatures.
  12. Mechanical and thermal recycling is much better.
