# [Foam Degradation Insights for Better Gasket Design](https://blog.marianinc.com/blog/foam-degradation)

Posted by [Ben Hvidston](https://blog.marianinc.com/blog/author/ben-hvidston)

 August 14, 2025 1:51 PM

![Expected Useful Lifespan of Device](https://blog.marianinc.com/hs-fs/hubfs/01-Product-Life-Spans.jpg?width=389&height=230&name=01-Product-Life-Spans.jpg)Understanding how different foams degrade is critical to designing gaskets that deliver optimal performance for their intended lifespan in any application. Learn what “long-term” reliability means in real-world environments and how polymer  degradation mechanisms impact sealing materials.

In this Enclosure Institute™ blog, Marian and Rogers Corporation explore the key factors contributing to foam material degradation, providing engineers with insights to design durable components that maintain reliable performance throughout the product’s operational life.

Check out the extended blog on the Rogers website, [Expert Tips for Preventing Polymer Degradation in Enclosure Applications](https://www.rogerscorp.com/blog/2025/expert-tips-for-preventing-polymer-degradation-in-enclosure-applications), and the[ video](https://youtu.be/pU6FI8VMa3c?si=OFdbugysrbHdIbCY) below.  

*\*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.*

## ![Forms of Degradation Comparison Chart](https://blog.marianinc.com/hs-fs/hubfs/Degradation-Comparison-Chart.png?width=375&height=375&name=Degradation-Comparison-Chart.png)Polymer Degradation Mechanisms

In polymer engineering, degradation refers to the breakdown of a material’s molecular structure and physical properties over time. In this series, we cover mechanisms such as:

- Oxidation 
- Hydrolysis
- UV exposure
- Ozone attack

[ASTM International](https://store.astm.org/d6954-18.html) describes degradation within the context of its standards, such as ASTM D6954, as a process where environmental conditions cause measurable changes that can impact performance.

Understanding the expected resistance to these degradation mechanisms is important when designing your seal to last the lifespan of the application.

 

 

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 where Phil and Jimmy share key insights into which materials thrive or fail under each degradation mechanism.
