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.

Product Name | Description |
---|---|
Vespel® ASB-0670 | DuPont™ Vespel®ASB-0670 parts are metal backed to offer enhanced load-carrying capacity, while providing a self-lubricating composite surface. The fabric component of ASB-0670 provides a low coefficient of friction and high strength to achieve superior wear life. |
Vespel® ASB-0826 & ASB-3000 | The DuPont™ Vespel® ASB parts graphite series offers high thermal oxidative resistance. By coupling the high temperature, self-lubricating properties of mechanical graphite with the appropriate selection of metal housings, DuPont can design a durable assembly that is easy to install and matches the CTE of the mating components. |
Vespel® ASB-5000 Series | The DuPont™ Vespel® ASB parts graphite series offers high thermal oxidative resistance. By coupling the high temperature, self-lubricating properties of mechanical graphite with the appropriate selection of metal housings, DuPont can design a durable assembly that is easy to install and matches the CTE of the mating components. |
Vespel® CP-0301 | Vespel® CP-0301 composite parts from sheet molding compound consist of long, chopped fibers held in a polymer matrix. The discontinuous nature of the fibers allows the fibers to align with the contours of the part, permitting the molding of relatively complex shapes, while providing reinforcing strength. Vespel® CP-0301 parts demonstrate high strength and low weight for aircraft clamps and similar components. |
Vespel® CP-0600 Series | Vespel® CP-0644, CP-0648 and CP-0650 composite parts consist of woven, carbon- fiber fabrics laminated in polyimide resin for strong, light, and durable components. |
Vespel® CP-0664 | Low-friction, low-wear fabric-reinforced composites that are “self-lubricating” under high loads. |
Vespel® CP-8000 Series | Vespel® CP-8000 series composite parts are made from fibers braided into hollow tubes held in a matrix of resins. This produces bushings that offer the best combination of properties for applications that require the benefits that a composite structure offers. |
Vespel® CP-9800 Series | Vespel® CP-9800 series is a clean, stiff, light-weight new end effector material. Custom parts made from this pitch-based carbon fiber and epoxy composite are designed specifically for the function required in the application. |
Vespel® CR-6100 | DuPont™ Vespel® CR-6100 is a composite material designed for use in hostile chemical environments. Stationary parts in this composite material meet the following specification per API STD 610/ISO 13709, Centrifugal Pumps For Petroleum Petrochemical and Natural Gas Industries:-46 to 230 °C (-50 to 450 °F) temperature limits and 2,000 kPa (20 bar; 300 psi) limiting pressure differential per wear part linear measure of 25 mm (1.0 inch). |
Vespel® SCP-5000 | DuPont™ Vespel® SCP-5000 is an unfilled polyimide polymer that offers high modulus and surface hardness and improved dimensional stability. Compared to traditional polyimides, it offers better strength and stiffness at high temperatures. |
