Polypropylene (PP)

  • Balanced properties make polypropylene ideally suited to use in everyday products and industrial applications alike
  • One of the most commonly produced plastics in the world, it is frequently used in packaging and industrial parts
  • Offers high levels of chemical resistance and electrical insulation, features excellent elasticity, toughness and fatigue resistance

An everyday and industrial hero

The universal standard plastic polypropylene, with its balanced properties, is used in many sectors, in daily as well as industrial applications. You can find it, for example, in your bicycle helmet or battery coatings. With a share of around 20 % in total production, it is the second most significant plastic. Polypropylene can be filled with mineral filling materials such as talcum, chalk or glass fibers. This significantly expands the potential spectrum of its mechanical properties such as stiffness, application temperatures and many others.

Flexibility, stability and resistance

Polypropylene is resistant to almost all organic solvents and fats as well as to most acids and bases. It is odorless and does not irritate the skin. The highest application temperature of polypropylene is 100 to 110 °C, and the crystallite melting range is between 160 to 165 °C. These temperatures can be influenced by specifically selecting polypropylene types. PP can therefore withstand higher temperatures than polyethylene (PE), as well as being harder and more solid.

Almost limitless applications

Polypropylene can be found in packaging foils for food and pharmaceuticals, apparatus, toolmaking, machine, container and laboratory construction, the construction sector and in storage technology. Typical examples are dashboards, pipelines, sportswear or transformer housings. If your project could benefit from polypropylene, we will work with you to realize it—we can produce just about any kind of plastic profile to fit your needs.
