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®, 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 Makrolon® polycarbonate, are used for back-lit instrument panels and LED light diffusers.
- Protection - 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.
Typical aerospace applications:
- Aircraft tray tables and arm rests
- Aircraft windows and canopies
- Air-return grills
- Avionics instrument panels
- Bearings and bushings
- Composite tooling
- Gears and gear spaces
- Guides and stops
- Interior components
- Valve seats and seals
- Slide rails
- Standoff insulators
- Wear pads
- Wire wrap insulation
Explore DuPont™ Vespel® & other high performance plastics
With innovative materials from the world’s leading manufacturers—including plastic with formulated PTFE, carbon graphite, and other additives—we can help you meet the most demanding specs or applications.
- Locking Fasteners and Splines - Materials such as authentic DuPont™Vespel®, offer 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.

Counterfeit DuPont™ Vespel® can ground your product & put your company at risk
Are you getting authentic materials? Do you have confidence in your supplier’s supply chain? Curbell Plastics is an authorized supplier of DuPont™ Vespel®. There are reports of unauthorized resellers attempting to sell the DuPont™ Vespel® product as to unsuspecting customers and alter the Certificate of Conformance (CoC). These altered CoCs do not contain the correct lot number information for traceability purposes. Purchasing materials from an unreliable (or unauthorized) supplier may pose a performance risk and product traceability is compromised.
- How can I tell whether or not the DuPont™ Vespel® shapes I have are authentic?
The first step to ensure that you are purchasing Authentic DuPont™ Vespel® shapes is to buy only from an authorized DuPont distributor, such as Curbell Plastics.
Product purchased from an authorized DuPont distributor will be labeled with a genuine DuPont™ Vespel® shapes product label and accompanied by an official CoC. The tamper-evident product labels are serialized to add a level of traceability and contain covert security technology that helps prevent counterfeiting of Authentic DuPont™ Vespel® shapes product labels. If you doubt that a product label is genuine, Curbell will verify its authenticity at no expense.
