Material selection related to seal performance is highly application specific. When choosing a sealing material, it's important to first understand if your application will be used in a static or dynamic environment. This ensures the appropriate materials are being considered for a gasket that maximizes enclosure reliability while also preventing premature failure.
In this Enclosure Institute™ blog, Marian and Rogers Corporation break down the differences between a static and dynamic seal, the design implications, and the key material properties that matter most.
Check out the blog on the Rogers website, Everything You Need to Know About Static vs Dynamic Seals in Enclosures, and the video below. The video also dives a little deeper into open cell and closed cell materials, their performance characteristics, and the various testing methods to verify those characteristics.

Sealing Materials - Static vs Dynamic Seals & Open Cell vs Closed Cell
Whether your enclosure is designed to remain closed for the duration of its life (static application) or is meant to endure thousands of open and close cycles (dynamic application), there are many things that play a role in a sealing gasket's performance like:
- Proper placement of the gasket
- Compression set and stress relaxation of the sealing material
- Conformability and environmental resistance of the sealing material
- And more
Along with understanding if your application is static or dynamic, being aware of the differences between open cell and closed cell materials and the forces required for each to maintain a seal is just as important in ensuring a successful seal.
