Vespel® CP Product Family

DuPont™ 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.

Composite parts can be found as replacements for  aluminum or titanium in tube clamps. Wear strips are “self-lubricating”.  Typically CP parts are used in aircraft bushings, wear pads, washers, bumpers and seals.

CP-0301                                                                              

Sheet-molded and reinforced polyimide resin is lightweight yet tough.  CP-0301 is used instead of aluminum or titanium in parts to save weight, reduce wear and friction, or reduce fatigue or vibration. CP-0301 tube clamps are more fatigue-resistant than those using die-cast aluminum.                                                                    

CP-0644, CP-0648 & CP-0650                                                                              

Fabric-reinforced composites can be  stronger than powder-filled compositions.  Lighter-weight than aluminum. Used in bushings and washers for high-temperature, highly oxidative environments and self-lubricating low-friction and wear.

CP-0664

Low-friction, low-wear fabric-reinforced composites that are “self-lubricating” under high loads.

CP-8000, CP-8001 & CP-8002                                                                              

Much like CP-0648, CP-0648 and CP-0650 but based upon fibers wound into a braided tube instead of a fabric.  Fibers align circumferentially with the bushing’s diameter to help better match CTE of the mating components.                                                                

Vespel® CP-9833 & CP-9836             

Fabric-reinforced composites that are lighter weight and dampen- vibration resistant more than traditional ceramic and aluminum for robotic end effector applications.

 
 
 
FEATURED

Vespel® products are made from a variety of materials (polyimides, thermoplastics, composites and chemically-resistant polymers). These products offer a unique combination of physical properties and design flexibility. Parts are available as custom parts, stock shapes, components or assemblies.

 
 
 
USES AND APPLICATIONS

DuPont Vespel® parts have a unique combination of properties that can replace metal, PEEK or ceramic parts in material handling equipment with high temperatures, high wear or no lubrication.

 
 
 
CASE STUDIES

Vespel® SCP-5050 sweep-out fingers and stacker bar inserts for glass handling help increase plant reliability and efficiency and reduce operating costs at Veda-Pack glass manufacturing sites

The operator of a pipeline in the Southwestern U.S. was searching for a case ring material for pumps that would enable improved operating efficiency, increase equipment reliability and avoid the seizing or galling problems encountered with metal components. The metal components were replaced with Vespel® CR-6100 parts, and the results were impressive.
