During rigorous application testing the company observed that other potential solutions such as thermoplastic bushings can actually get hot enough to melt.
Vespel sp 21 rod.
Sp 21 is a graphite filled polymer.
Vespel sp 21 has the highest mechanical properties of the graphite filled grades.
Use these rods to make valve components and seal rings.
Dupont vespel polyimide is an extremely high temperature creep resistant material that is often used in high heat environments where thermoplastic materials would lose their mechanical properties.
It also has excellent wear resistance up to 300 f 149 c.
Vespel sp 21 has the highest mechanical properties of the graphite filled grades.
It provides low friction for bearing and wear thrust washers and dynamic seals.
Sp 21 is graphite enhanced with low friction properties for use with or without lubrication in various applications.
