Vespel ®

Temperature extremes, high friction, and heavy loads? Vespel® has outperformed other engineering materials under the most severe conditions since 1965. Highly demanding applications like aerospace components, semiconductor processing, automotive manufacturing, and energy production rely on Vespel® parts to keep their equipment running. Vespel® polyimide materials provide continuous operation at cryogenic to high temperatures; low wear and low friction at high PV in lubricated or unlubricated environments; outstanding creep, strength, and impact resistance; exceptional dimensional stability; low thermal expansion; and easy machinability. Vespel® makes lighter weight parts not only practical, but, in many cases, better than standard metal, ceramics, and other engineering polymers such as PEEK (polyether ether ketone) and PAI (polyamide-imide). With design centers in Asia, Europe, and the Americas, DuPont technicians collaborate with customers to combine materials science with design to produce high-performance parts and keep production running smoothly. Vespel® parts and shapes, both custom and stock, have been tested and proven effective in highly demanding applications around the globe. They are available in sheet, rod, tube, plaque, bar, disk, ring, ball, and custom machined parts.

DuPont Kalrez® and Vespel® Center of Excellence

When sealing matters, choose DuPont Kalrez® and Vespel® products. DuPont™ Kalrez® and Vespel® work with customers to bring state of the art technology to solve customers’ toughest application challenges.

Vespel - Lubricated Wear and Friction Testing

DuPont VESPEL SP polyimide bearings have been hard at work for more than twenty years, keeping equipment running longer and with less maintenance than conventional bearing materials.

DuPont Kalrez® and Vespel®

Perfluoroelastomer parts have been the sealing material of choice for long-term reliable sealing in the harshest chemical environments. Today, elastomeric seals are expected to perform in a variety of even more aggressive chemicals and at higher temperatures. 

Vespel® - Taking the Heat

Without a doubt Vespel ® can take the heat. This non-melting polyimide can withstand repeated heating up to 300° C without altering its thermal or mechanical properties, making it a popular choice for jet engines, industrial machinery, cars, trucks, and other vehicles.
