Polypropylene products and applications

Since its discovery in the early 1950s and commercialization in 1960, polypropylene (PP) has become one of the world's most versatile polymers. Its versatility stems from the fact that PP has the lowest density among the commodity plastics, excellent chemical resistance and can be processed by many converting methods such as injection molding and extrusion.

Demand for PP has historically exceeded GDP growth. This level of growth is expected to continue due to PP’s penetration into appliance, automotive, consumer films, nonwoven fabrics and fiber end uses.

PP's versatility comes from its broad range of properties, including high stiffness in homopolymers, excellent low-temperature impact strength in impact copolymers and excellent clarity and low melting point in random copolymers.

Product families
PP products can be grouped into three product families, with the following approximate market share:

  • Homopolymer (HP): 65-75%
  • Impact copolymer (ICP): 20-30%
  • Random copolymer (RCP): 5-10%
