Rulon® and Meldin® Materials for Aerospace
The extremely demanding aerospace market is ideal for our high performance Rulon and Meldin materials, which separately or in combination, can help solve the most complex technical problems. Our Meldin polyimide materials, with their high temperature resistance and mechanical strength properties, are particularly well-suited for these stringent applications. Equal to the task, our Rulon products offer solutions for applications where excellent wear-resistance and chemical compatibility are required to ensure long life in harsh environments.

Case Study
Application: Aircraft Air Conditioning System
Material: Meldin® 7022
| Features / Benefits | - Can withstand high bleed air temperatures
- Low thermal expansion allows small clearances
- Tight tolerances can be machined easily
- Compatible with common aerospace fluids
|
- Meldin® 7022 has the lowest coefficient of thermal expansion (CTE) in the Meldin® 7000 Series, making it ideally suited for applications that require tight clearances over a wide temperature range. The CTE comes very close to aluminum, making it ideally suited for leakage control in aerospace applications.
