DuPont™ Vespel® SP-1 Rod

Vespel® SP polyimide Rod is produced from advanced polymers developed by DuPont. SP-1 is an unfilled Vespel® available in rod and sheet options in a range of standard and cut-to-size options. Vespel® polyimide is widely known and a popular material choice because it provides superior wear and delivers long term performance under extreme operating conditions.
 
Vespel® SP-1 also has low electrical conductivity, excellent thermal insulation properties and performs well in vacuum applications.  It also possesses the highest elongation and purity of the entire SP line of materials. One of the most unique properties of DuPont™ Vespel® is its ability to retain its mechanical properties in extreme temperatures, providing superior performance for a range of high temperature, low temperature and high-pressure applications.
 
Additional features and benefits of Vespel® SP-1 include:

• UL rated for low electrical and thermal conductivity

• Excellent wear resistance

• Resists thermal oxidation

• Maximum strength and elongation

• Exceptional dimensional stability

• Low friction and high stability

• Excellent creep resistance

• Low outgassing

Vespel® SP-1 is a high-performance polyimide that is lightweight, low wear and low friction. Because it provides high load resistance for use with high shaft speeds, Vespel® is a suitable material for use in for bearings and other high load applications. Vespel® SP-1 has also been tested to perform in environments where there is exposure to radiation, making it useful for remote handling and other automated equipment in environments where there is significant radiation exposure.
 
Vespel® SP-1 can be easily machined for prototype and low volume production of standard and complex parts and is ideal for applications where there are wear, friction and sealing challenges. Some of the more common applications for Vespel® polyimide include:

• Valve seats

• Spacers

• Fixtures

• Balls

• Gaskets

• Poppets

• Seals

• Locking fasteners

• Insulators

• Wafer clamping

• In-chamber semiconductor parts
