Vespel® Polyimide Parts and Shapes:

Trusted in Extreme Conditions and Demanding Environments

Temperature extremes, high friction, and heavy loads?  Vespel® has outperformed other engineering materials under the most severe conditions since 1965. 

For highly demanding applications  like aerospace components, semiconductor processing, automotive manufacturing, and energy production rely on Vespel® parts to keep their equipment running.

Outstanding temperature, mechanical and PV properties.Vespel® polyimide parts and shapes 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).

Global solutions. With design centers in Asia, Europe, and the Americas, Dupont Engineers and Scientists collaborate with customers to combine materials science with design to produce high-performance parts and keep production running smoothly.

Wide range. 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, direct formed and custom machined parts.

Uses

• Bearings, bushings, insulators, seals, thrust washers, and wear rings
• Wear pads, wear strips, and tube clamps
• Thermoplastic injection-molded, assembled, and composite parts
• Test sockets and wafer guides
• Glass handling technology
• Wear components in centrifugal pumps
• Hydrocarbon, chemical, and water service pumps

Advantages

• Low creep and low out-gassing
• Lightweight yet handles high loads
• Chemical, electrical, wear, and thermal resistance
• Strength, stiffness, and dimensional stability
• Easy to machine and can be machined to very close tolerances
• Works well under hard vacuum, radiation, oxygen compatibility, cryogenic conditions, and exposure to flame
• Costs less to manufacture than ceramic
