PP (Polypropylene)

PP is a semi-crystalline, thermoplastic material with similar properties as PE-HD.

However, it has higher strength, rigidity and hardness. Below freezing, however, PP is very sensitive to impact. Its chemical resistance is comparable to that of PE.


The properties of PP are:
  • Low density compared to other materials
  • Minimal water absorption
  • Excellent chemical resistance even against solvents
  • High corrosion resistance
  • Relatively high surface hardness
  • Very good electrical insulator
  • Sensitive to cold
  • Weldable
  • Very reasonably priced material


PP can be applied in the following areas:
  • Pump and valve parts
  • Gaskets
  • Components in electroplating
  • Chemical tank and apparatus construction
  • Air conditioning and ventilation technology
  • Medical engineering

Modification options

  • PP-GF30 (with 30% glass fibre for higher stiffness and dimensional stability)
  • PPs (Poly-Propylene, flame retardant)
