Polypropylene (PP) and polypropylene compounds (PPC)
The semi-crystalline thermoplastic polypropylene (PP) belongs to the group of polyolefins and is produced by polymerisation of propene, a monomer. An important property of the material is its very good resistance to organic solvents and fats, as well as acids and alkalis. PP has a lower density than other plastics and an upper continuous service temperature of 100 to 110 °C.
Polypropylene compounds are produced using a blend of one or more basic polyolefins and various modifiers, for example for improved impact strength, filler materials such as glass fibres or carbon fibres and/or additives.
Fillers Improve Mechanical Properties of PP
The stiffness, hardness and strength of PP are lower compared to other plastics such as polyamide, but can be increased by fillers. The addition of mineral fillers such as talc and mineral, carbon or glass fibres is common. This opens up a wide range of application areas. In the automotive sector, PP compounds can be used in interior and exterior applications as well as in the engine compartment, due to their high chemical resistance.
Examples are dashboards, covers, crash absorber elements and battery housings. PP with heat and UV stabilisers is used for electrical applications.
