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
