DuPont Kalrez® and Vespel® Center of Excellence
When sealing matters, choose DuPont Kalrez® and Vespel® products. DuPont™ Kalrez® and Vespel® work with customers to bring state of the art technology to solve customers’ toughest application challenges.
Vespel - Lubricated Wear and Friction Testing
DuPont VESPEL SP polyimide bearings have been hard at work for more than twenty years, keeping equipment running longer and with less maintenance than conventional bearing materials.
DuPont Kalrez® and Vespel®
Perfluoroelastomer parts have been the sealing material of choice for long-term reliable sealing in the harshest chemical environments. Today, elastomeric seals are expected to perform in a variety of even more aggressive chemicals and at higher temperatures.
Vespel® - Taking the Heat
Without a doubt Vespel ® can take the heat. This non-melting polyimide can withstand repeated heating up to 300° C without altering its thermal or mechanical properties, making it a popular choice for jet engines, industrial machinery, cars, trucks, and other vehicles.

Vespel® SP-2515
Chemical Family: Polyimides
Polymer Name: Polyimide (PI)
Parts made from Vespel® SP-2515 offer a low coefficient of thermal expansion (CTE), excellent wear against both aluminum and steel alloys, and a low coefficient of friction in both dry and lubricated conditions. These properties make Vespel® SP-2515 parts ideal for applications such as seal rings, thrust washers, and bushings where high energy efficiency and dimensional stability, over a broad range of temperatures, are a requirement.
Vespel
Vespel® ST-2030
Chemical Family: Polyimides
Polymer Name: Polyimide (PI)
Vespel® ST-2030 parts and shapes are used in applications in which low thermal expansion is more important than strength (which is slightly reduced). Applications may include bearings, bushings and washers. ST-2030 is a filled polymer with a lower coefficient of thermal expansion and lower elongation than ST-2010.
