Polyethylene or polythene (abbreviated PE; IUPAC name polyethene or poly(methylene)) is the most commonly produced plastic.
In the aerospace context, polyethylene is a type of plastic that is used in a variety of applications due to its low weight, high strength, and durability. Polyethylene is widely used in aerospace industry for various applications such as insulation, packaging, and structural components.
Some examples of the use of polyethylene in the aerospace industry include:
- Polyethylene foam is used as insulation material in aircraft and spacecraft. It is lightweight, has good thermal insulation properties and is resistant to chemicals and moisture.
- Polyethylene is used in the production of lightweight packaging materials for aerospace equipment, it is also used in the production of protective covers and bags for equipment and cargo.
- Polyethylene is also used in the production of composite materials that are used in the manufacturing of aircraft parts such as radomes, interior and exterior panels, and fairings.
Polyethylene'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.
