More About
Vespel is a high-performance polyimide material developed by DuPont™, renowned for its exceptional combination of thermal stability, strength, and wear resistance. Vespel rods are used in environments where traditional plastics fail, including temperatures exceeding 300°C, high loads, vacuum conditions, and chemically aggressive environments.
These rods retain their mechanical integrity, dimensional accuracy, and low friction characteristics even in continuous service at high temperatures, making them ideal for bearings, bushings, insulators, and sealing components. At Petron Thermoplast LLC, we offer authentic DuPont™ Vespel® rods in various grades, diameters, and lengths, fully compliant with international standards.
