Vespel® Parts & Shapes

Meet the Challenge With Vespel® Parts and Shapes

Vespel® parts and shapes provide high-performance solutions for the toughest sealing, wear, or friction challenges.

DuPont™ Vespel® parts and shapes are formed by the needs of each customer. Their properties help overcome severe sealing, wear, or friction challenges, endure high temperature, and stand up to some of the world’s harshest operating environments.

With design centers of excellence in Asia, Europe and the Americas, DuPont combines material science with unique collaborative design resources for customers. Vespel® parts and shapes, both custom and stock, have been tested and proven effective in highly demanding applications around the globe.

Vespel® parts and shapes can keep production running more smoothly, improve throughputs, and extend service intervals. The performance of Vespel® parts can also make lighter-weight parts not only practical, but better than standard metal, ceramics and even other engineering plastics.


Centers of Excellence for Application Testing



  • Vespel® Stock Shapes

  • Vespel® Custom Plastic Parts

  • Vespel® S Family

    Vespel® S products are highly durable polyimides used in demanding applications where exceptional thermal resistance (cryogenic to 349°C), low wear and/or low friction, strength and impact resistance are desired as custom parts or stock shapes.

  • Vespel® CR Product Family

    Vespel® CR products provide excellent chemical resistance in refineries and chemical processing. They offer high-creep resistance and easy machinability for wear rings and tight-tolerance parts like ball-valve seats.

  • Vespel® ASB Assemblies

    Vespel® ASB assemblies include fiber/fabric reinforced composites with metal backing that offer low wear & friction plus self lubrication, and metal-backed carbon-graphites for self-lubricating wear at extreme temperatures.

  • Vespel® TP Family

    Vespel® TP thermoplastic family offers many products with excellent strength and toughness, dimensional stability, low outgassing, creep resistance, and low coefficient of thermal expansion for aircraft, automotive and industrial applications.

  • Vespel® CP Product Family

    Vespel® CP parts offer an array of fiber or fabric reinforced composites for a range of unique design needs when wear and strength are key. Typically CP parts are used in aircraft bushings, washers, bumpers and seals.

  • Mitsui AURUM® TPI resin

    A melt-processable, thermoplastic polyimide resin that lends itself to injection molding and extrusion. Offering continuous use temperatures to 240°C (464°F), AURUM® parts exhibit low outgassing, superior radiation resistance, excellent wear performance and resistance to chemicals.
