DuPont™ Vespel® Sheet & Plaque

About DuPont™ Vespel® Sheet & Plaque

DuPont™ Vespel® sheet and plaque are flat stock forms used for high-performance machined parts in applications that may require heat resistance, wear resistance, low friction, and long-term performance. Learn more about DuPont™ Vespel® polyimide and its material properties.

Curbell Plastics supplies authentic DuPont™ Vespel® plaque for machined-part applications where material quality, traceability, and consistent supply matter. If you are evaluating Vespel® for an application, we can help you identify an appropriate grade and starting stock form. Contact Curbell Plastics to discuss your application or get a quote.

DuPont™ Vespel® Plaque for High-Performance Machined Parts

DuPont™ Vespel® polyimide is often considered for applications that push beyond the limits of standard engineering plastics.

It is commonly evaluated where parts must:

• Maintain performance at elevated temperatures
• Resist wear and friction
• Hold tight tolerances
• Support long-term performance in demanding applications

Vespel® plaque is often selected as a starting stock form for machined parts used in aerospace, semiconductor and electronics manufacturing equipment, high-temperature, and other industrial applications.

What is DuPont™ Vespel® Sheet or Plaque Used for?

Vespel® plaque is a practical starting form for parts with flat or plate-like geometries. These flat stock forms may be listed as sheet or plaque in DuPont™ Vespel® stock-shape and product references.

They are commonly used for:

• Prototype and qualification work
• Parts machined from flat stock

Square plaque is a common flat stock form for these applications. It is often associated with commonly specified grades such as SP-1, SP-21, SP-22, SP-211, SP-3, and SP-202. Typical standard plaque sizes may include 10″ x 10″, 5″ x 5″, and 5″ x 10″, with available thicknesses varying by grade and current availability. Buyers looking for available stock forms can also shop DuPont™ Vespel® polyimide online.

Available sizes and thicknesses vary by grade and availability. Contact Curbell Plastics to discuss current options for your application.

Which DuPont™ Vespel® grades are commonly available in sheet or plaque?

The right grade depends on the performance requirements of your application. These are some of the most commonly specified options for plaque-based parts.

See the individual grade pages for more detailed property, application, and availability information.

Grade and Shape Considerations

Grade availability can vary by stock form. If you are specifying Vespel® plaque for a machined part, it is helpful to confirm both grade and starting shape early in the sourcing process because material composition, geometric size or shape, and manufacturing process are part of what defines authentic DuPont™ Vespel® shapes.

Typical considerations include:

• Grade requirements
• Plaque dimensions and thickness
• Machining approach
• Documentation and traceability needs

If you are not sure which grade or form to start with, Curbell Plastics can help you review available material options and stock forms.

Machining Parts from Vespel® Plaque

Vespel® plaque is commonly used as starting stock for machined parts. It is often considered for:

• Prototype and qualification work
• Complex part geometries machined from flat stock

Used for High-Performance Components

Vespel® plaque is used to manufacture parts such as:

• Bearings and bushings
• Seals and valve components
• Insulators
• Wear pads and wear strips
• Thrust washers
• Precision machined components

These parts are typically used in environments where heat, friction, wear resistance, chemical exposure, or long-term performance are important considerations

Why Authentic DuPont™ Vespel® Sourcing Matters

When specifying DuPont™ Vespel® materials, authenticity and traceability are important. Sourcing from a DuPont™ authorized distributor can help support material consistency and documentation needs for demanding applications.

If your application depends on consistent material sourcing, contact Curbell Plastics to discuss your specifications and documentation needs.
