Replace Metals with Plastics, to Achieve Weight & Cost Savings

High performance engineering plastics are a natural fit for the aerospace industry due to their light weight compared with other industrial materials. A typical engineering polymer has half the density of aluminum or glass and 1/6th the density of steel.

Many High-Performance Engineering Plastics:

  • Have outstanding flame, smoke, and toxicity characteristics
  • Can handle 400°F and higher for long periods of time, and can withstand large temperature swings
  • Resist aviation fuels and other chemicals
  • Are tough, impact resistant, and stand up to vibration and abrasion
  • Give you design freedom, including many color and surface texture options for aircraft interiors
  • Have good sealing characteristics
  • Perform well in bearing and wear applications
  • Offer transparency for windows and aircraft canopies
  • Have electrical insulating properties

For Demanding Applications in Aviation, Plastics Help You Soar

Leading aerospace companies use our lightweight plastics to keep passengers comfortable, protect vital electronics, and improve reliability of mission-critical components.

Cabin Interiors

Aerospace grades of plastic sheet such as KYDEX® Thermoplastics, a family of high impact, fire-rated thermoplastic materials and Royalite®, fire-rated, rigid ABS/PVC thermoplastic materials, are engineered to have the durability, cleaning chemical resistance, and fire resistance required for aircraft interiors. These materials are thermoformed and used as tray tables, arm rests, and seat backs.

Back-lit Panels

Aerospace grades of TUFFAK® polycarbonate, are used for back-lit instrument panels and LED light diffusers.


Plastic spiral wrap insulation, convoluted tubing, and heat shrink tubing are used to protect wire and cable in the aircraft cabin from vibration and abrasion during flight.

Locking Fasteners and Splines

Materials such as authentic DuPont™Vespel®, DuPont™ Vespel® Splineoffer important advantages compared with metals in that they are less likely to damage mating parts during assembly and disassembly. The Vespel® Family of materials may be a good choice for aerospace locking fasteners and splines where good mechanical properties and dimensional stability are required throughout a wide operating temperature range from cryogenic to 550°F with excursions to 900°F.

Valve Components

Aircraft and spacecraft rely on the controlled flow of liquids and gasses, including hydraulic fluids, lubricating oils, cabin air, and engine bleed air during operation. Valves play an important role in controlling the flow of aircraft fluids and gases and high performance polymers such as PEEK, PCTFE, and DuPont™ Vespel®, are often used for valve seats and seals. These materials have the chemical resistance, creep resistance, and wear properties required for aircraft fluid handling applications.
