Advantages of PPSU rods and boards in aerospace applications


PPSU rods and boards offer a weight reduction of up to 40% compared to traditional materials such as aluminum or steel. This can lead to significant fuel savings and increased efficiency.

High strength and durability:

PPSU is highly resistant to impact, heat and chemicals. It has excellent mechanical properties and can withstand extreme temperatures, making it ideal for use in challenging aerospace environments.


PPSU is highly resistant to corrosion, making it an excellent choice for use in humid or corrosive environments.

Easy to machine:

PPSU is easy to machine and can be easily formed into complex shapes. This makes it ideal for use in a range of aerospace components such as brackets, housings, and connectors.

Applications of PPSU rods and boards in aerospace:

PPSU rods and boards are used in a range of aerospace applications such as:

Structural components:

PPSU rods and boards are used in structural components such as fuselage frames, wing spars, and landing gear components.

Electrical components:

PPSU is an excellent electrical insulator and is used in electrical components such as connectors, switch housings, and wiring harnesses.

Interior components:

PPSU rods and boards are used in interior components such as seats, tray tables, and overhead bins due to their lightweight and durable properties.
