Polypropylen PP

Polypropylene resembles PE in many ways. Due to its higher stiffness and higher service temperature when compared to PE, it has captured its own field of applications.


Special characteristics of PP are:

  • very low density
  • high hardness, stiffness, and strength in the polyolefines area
  • relatively high dimensional stability under heat
  • low toughness at low temperatures up to approx. 0 °C
  • good chemical resistance
  • very low water absorption
