Vespel

Vespel® is DuPont's durable and high performance polyimide plastic. It offers high resistance to heat, chemical, creep, and radiation. Good dimensional stability and lubricity combined with other mechanical and thermal properties make it a best performing polymer in transportation and semiconductor technology.

Vespel continuouslyperforms well from cryogenic temperatures to 5000F/2880C. It has significantly low outgassing, high reproducibility, and consistency of its thermo-physical properties. Vespel is easy to machine and offers long life and low wear even in severe environmental conditions.
