Polypropylene is the world’s second-most widely used synthetic plastic. This versatile thermoplastic polymer can be used to produce a broad spectrum of products, from laboratory equipment and automotive components to packaging products and textiles like carpet and rope.

The material is made by combining multiple propylene monomers (hence the name); it is easily copolymerized with other polymers (such as polyethylene) to create even more versatile materials. Polypropylene is easy to recycle.

Advantages of Polypropylene

  • Excellent elasticity and toughness
  • Good chemical and fatigue resistance
  • Resistant to stress-cracking, even when flexed
  • Durable and resistant to water, detergents, acids, and bases

Properties of Polypropylene

Polypropylene has the lowest density (between 0.895 to 0.92 g/cm3) of any commodity plastic. Fillers and additives can raise the material’s density, where needed. Polypropylene’s toughness and flexibility make it comparable to HDPE in “engineered plastic” applications.

At room temperature, polypropylene is resistant to fats and most organic solvents (excluding strong oxidants).  Generally, the material provides a slippery surface that makes it an ideal choice for low friction applications like gears. Polypropylene’s flexibility and toughness make it the perfect material for living hinges.
