Polypropylene (PP), also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene.
In the aerospace context, polypropylene is a type of plastic that is used in a variety of applications due to its low weight, high strength, and durability. Similar to polyethylene, polypropylene is widely used in aerospace industry for various applications such as insulation, packaging, and structural components.
Some examples of the use of polypropylene in the aerospace industry include:
- Polypropylene fibers are used to produce high-strength, lightweight composite materials that are used in the manufacturing of aircraft parts such as radomes, interior and exterior panels, and fairings.
- Polypropylene is used to produce lightweight packaging materials for aerospace equipment, it is also used in the production of protective covers and bags for equipment and cargo.
- Polypropylene is also used in the production of lightweight, high-strength insulation materials that are used to insulate aircraft and spacecraft.
- Polypropylene is also used in the production of electrical components and connectors for aerospace applications, due to its good electrical insulation properties and its resistance to chemicals, temperature and moisture.
Like polyethylene, polypropylene's properties make it a suitable choice for aerospace applications where weight reduction and durability are important factors. It is also non-toxic, easy to process, and has a low cost.
