Vespel Sheet, Rod, Film & Tube

Vespel polyimide is a high performance polymer mostly used in aerospace, semiconductor and transportation technology. It combines heat resistance, lubricity, dimensional stability, chemical resistance and creep resistance, to be used in hostile and extreme environmental conditions.

Unlike most plastics, vespel polyimide does not produce significant outgassing even at high temperatures, which makes it useful for lightweight heat shields and crucible support. It also performs well in vacuum applications, down to extremely low cryogenic temperatures. However, Vespel tends to absorb a small amount of water, resulting in longer pump time while placed in a vacuum.

Although there are polymers surpassing polyimide in all these properties, the combination of them is the main advantage of Vespel. We have Vespel available in sheet, rod, film, and tube for all applications.
