Vespel®

Vespel® is a high-performance polyimide renowned for its exceptional strength, thermal resistance, and durability in extreme environments. It is the ideal choice for applications requiring reliable performance under continuous use temperatures up to 500°F (260°C) and short-term exposure up to 900°F (482°C).

Vespel® offers unparalleled advantages over traditional materials such as metals, ceramics, and other plastics. Its unique properties make it a preferred solution for aerospace, automotive, and industrial applications. Vespel® is lightweight, wear-resistant, and maintains dimensional stability across a wide temperature range. It is also resistant to most chemicals, ensuring long-lasting performance in demanding environments.

This specially engineered material combines low friction, high strength, and excellent thermal stability, making it suitable for components like bearings, seals, thrust washers, and electrical insulators. Vespel’s low outgassing properties also make it ideal for vacuum and aerospace applications.

Vespel® Advantages:

• High Temperature Resistance: Continuous use at 500°F, with short-term exposure up to 900°F.
