  Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. It is used in a variety of applications to include packaging for consumer products, plastic parts for various industries including the automotive industry, special devices like living hinges, and textiles.

  One of the major benefits of Polypropylene is that it can be manufactured (either through CNC or injection molding, thermoforming, or crimping) into a living hinge. Living hinges are extremely thin pieces of plastic that bend without breaking (even over extreme ranges of motion nearing 360 degrees). They are not particularly useful for structural applications like holding up a heavy door but are exceptionally useful for non load-bearing applications such as the lid on a bottle of ketchup or shampoo. Polypropylene is uniquely adept for living hinges because it does not break when repeatedly bent. One of the other advantages is that polypropylene can be CNC machined to include a living hinge which allows for faster prototype development and is less expensive than other prototyping methods.

  Another advantage of Polypropylene is that it can be easily copolymerized (essentially combined into a composite plastic) with other polymers like polyethylene. Copolymerization changes the material properties significantly, allowing for more robust engineering applications than are possible with pure polypropylene (more of a commodity plastic on its own).

  What are the Advantages of Polypropylene?

  Polypropylene is readily available and relatively inexpensive.

  Polypropylene has high flexural strength due to its semi-crystalline nature.

  Polypropylene has a relatively slippery surface.

  Polypropylene is very resistant to absorbing moisture.

  Polypropylene has good chemical resistance over a wide range of bases and acids.

  Polypropylene possesses good fatigue resistance.

  Polypropylene has good impact strength.

  Polypropylene is a good electrical insulator.
