Marian has a brand new demonstration piece to share with the world! Strategically named "Test My Memory," the demo illustrates the impact of compression cycling over time with 4 different foams. "Test My Memory" demonstrates that certain foams depreciate as it takes on impact over time, whereas other foams such as PORON® Urethaneand BISCO® Silicone resist the compression set, ensuring an excellent seal. Foams that resist a compression set make for a good seal in a gasket because the material rebounds to fill any potential gaps that could allow for water or other outside particles to pass through.

Compression Force Deflection in Foam Gaskets: A Critical Property

Applications that experience periodic compression cycling over time may require a gasket that is capable of compression rebound. In the event that your application uses a material that does not resist compression force, the material may depreciate over time. When your gasket has dwindled or has deteriorated from all of the periodic compression cycling, your gasket will become ineffective and will need to be replaced. In a perfect world, your gasket should rebound to fill any potential gaps. Using a material with great compression resistance will guarantee a long-term sealing performance that will work just as effectively each time you reseal your application.
