Sterling provides aircraft manufacturers with a range of specialized plastics in the production of both interior and structural components, valued for their strength, lightweight nature, resistance to extreme temperatures, and compliance with stringent safety and regulatory standards. Some commonly used plastics include:

1. PEEK (Polyether Ether Ketone) – Known for its high strength and chemical resistance, PEEK is used in parts that must withstand high mechanical loads, such as bushings, bearings, and structural brackets.

2. Polycarbonate – This durable, impact-resistant plastic is often used for windows, cockpit canopies, and interior paneling due to its transparency and toughness.

3. PPS (Polyphenylene Sulfide) – PPS is highly resistant to chemicals and heat, making it suitable for engine components, fuel systems, and other high-temperature areas.

4. Ultem® (Polyetherimide) – Ultem is a high-performance thermoplastic that offers flame resistance and is often used in aircraft seating and interior panels.

5. PTFE (Polytetrafluoroethylene) – Known by the brand name Teflon®, PTFE is used for seals, gaskets, and insulation, particularly where low friction and chemical resistance are required.

6. Nylon – Lightweight and strong, nylon is used in bearings, gears, and fasteners, as it offers good wear resistance and can handle moderate temperature ranges.

7. PMMA (Polymethyl Methacrylate) – Known as acrylic or Plexiglas®, PMMA is used for windows and light covers due to its clarity, UV resistance, and durability.

8. Composite Plastics (such as CFRP – Carbon Fiber Reinforced Polymer) – While not a pure plastic, CFRP combines carbon fiber with a plastic matrix, offering exceptional strength-to-weight ratios. It is widely used in structural components like wings and fuselage sections.

These materials help improve fuel efficiency by reducing the overall weight of aircraft while meeting regulatory standards for safety, durability, and thermal stability. As the aerospace industry continues to innovate, the use of high-performance plastics in aircraft manufacturing is expected to grow.
