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](https://www.rogerscorp.com/blog/2025/everything-you-need-to-know-about-static-vs-dynamic-seals-in-enclosures), and the[ video](https://www.youtube.com/watch?v=f2MHarV7eRs) 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.  *\*Disclaimer: The [Enclosure Institute™](https://marianinc.com/enclosure-institute/) is a free educational resource created by Marian, Inc. and Rogers Corporation to help engineers navigate enclosure sealing with expert guidance.* ## 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.     Check out best practices and take learn more about PORON® microcellular polyurethanes and BISCO® silicones that help prevent early failures and maintain reliable seals over time. Make sure to also watch the video above for a discussion on open cell versus closed cell materials with Jimmy and Phil. ![Open cell vs closed cell comparison](https://blog.marianinc.com/hs-fs/hubfs/Open-vs-Closed-Cell-Structure.jpg?width=602&height=250&name=Open-vs-Closed-Cell-Structure.jpg) [Read the full blog static vs dynamic seals on Rogers’ website here.](https://www.rogerscorp.com/blog/2025/everything-you-need-to-know-about-static-vs-dynamic-seals-in-enclosures)   ---   Sign up for the Enclosure Institute™ for more exclusive content like this (and more) and be the first to know when new content goes live.
