Polypropylene (PP)

Polypropylene (PP) is a semi-crystalline commodity. Polypropylene can occur as a homopolymer, random or block copolymer depending on the polymerization method.Polypropylene can also be mixed with elastomers e g EPDM), filled with talc (chalk) or reinforced with glass-fibre. In this way it is possible to obtain more grades with widely differing characteristics than can be achieved for any other plastic. Certain grades of Polypropylene can handle a continuous temperature of 100 C plus peaks of up to 140 C, and can therefore be classified as engineering plastics.

PP Properties

  • Low material cost and density
  • Excellent chemical resistance
  • Does not absorb moisture
  • Food approved grades are available
  • Fatigue resistance
  • Poor UV resistance (unmodified)
  • Brittle at low temperatures (unmodified)
  • Poor scratch resistance


Mape Plastics offer a broad variety of PP in several grades from world leading producers.

Our partner Repsol and their product ISPLEN®, offer different PP grades for many different areas, like medical healthcare applications for example. Repsol offer technical solutions to all kinds of markets in need of polypropylene.
