Polypropylene

Polypropylene is an extremely versatile plastic that is produced by the polymerisation of propene using Ziegler-Natta catalysts. Unlike its relative, polyethylene, polypropylene is largely isotactic, which means that its molecular chains have a regular arrangement. This structure gives it remarkable rigidity and hardness, making it one of the hardest polyolefin polymers. It retains these properties even at high temperatures.

Isotactic polypropylene (PP) is a true all-rounder with a balanced spectrum of properties. It offers average strength, rigidity and impact toughness, which makes it ideal for a wide range of applications. It also has a low density, which means that it is light but nevertheless robust. Its outstanding chemical resistance makes it particularly suitable for environments in which contact with various substances is unavoidable.

One remarkable property of polypropylene is its special flexural fatigue strength, which enables it to withstand extreme loads, even over long periods. This property makes it particularly attractive for applications that require high mechanical stress, such as in the automotive or construction industry.
