Keeping moisture out of an enclosure isn't just about choosing a closed cell material—it's about choosing the right one for your clamping force and application.

Modified closed cell silicone foams offer the moisture-sealing performance of traditional closed cell foams with improved compressibility and conformability, making them well-suited for enclosures with low-to-moderate compression forces. They're an excellent choice for protecting electronics from humidity, condensation, and water ingress without placing excessive stress on housings or fasteners.

Our latest blog explores how these materials differ from traditional closed cell silicone foams, what deflection and firmness mean for gasket performance, and how to select the right material for your enclosure design.

Not all conductive silicones are designed for vacuum or ultra-clean environments.

For aerospace, defense, optics, and cleanroom electronics, material selection requires more than effective EMI shielding. Low outgassing, conductive silicones help protect sensitive optics, sensors, and electronics by minimizing volatile emissions while maintaining electrical conductivity, environmental sealing, and reliable performance across extreme temperatures.

Our latest blog explores what makes these specialized materials different, the standards they meet, and where they're used—from satellites and spacecraft to medical imaging systems and semiconductor equipment.

Read the full article to learn how low outgassing, conductive silicones can help meet demanding application requirements.
