PlasticsPolypropylene (PP)
Description:
Polypropylene (PP) is a semi-crystalline thermoplastic and belongs to the group of polyolefins.
History:
Polypropylene was probably first produced by John Hogan and Banks around 1951. However, the first large-scale synthesis did not begin until 1957 through the work of Giulio Natta.
Structure and properties:
Polypropylene is obtained by polymerizing the monomer propene with the help of catalysts.
- Plastic with the lowest density
- Higher hardness and strength than PE, but lower than other plastics
- Resistant to many organic solvents and fats
- Resistant to many acids and alkalis
- Odourless and skin-friendly
- Physiologically harmless
Areas of application:
interior fittings for cars, dashboards, battery housings, insulation materials, conveying of corrosive gases, medical products
