More About
Vespel is a DuPont-engineered polyimide resin, renowned for its ability to maintain dimensional stability and mechanical integrity even at extreme temperatures up to 300°C. A Vespel Tube is a hollow cylindrical component used in high-performance mechanical, electrical, and thermal applications where standard plastics or metals fail.
It combines lightweight performance with strength and resistance to wear, creep, and chemicals, making it ideal for bushings, spacers, insulators, and seals in aerospace, automotive, and electronic systems.
