While you might think pressure sensitive adhesives (PSAs) are pretty straightforward, selecting the wrong for your enclosure application can create problems and compromise sealing performance long before final assembly takes place. 

Learn the key features of each adhesive type in latest blog on the Rogers website, How to Choose the Right PSA for Your Enclosure Components, and the video below to get an idea of which adhesives perform well in different situations. Once you have an understanding, you can start designing more reliable sealing components for your enclosure applications.

In Part 2 of our gasket failure series, we shift from the discussion on material science & environmental factors to mechanical design & real-world installation. Even a high-performance gasket can fail due to poor geometry, fastener placement, uneven compression, lack of venting, or improper gasket placement altogether.

Even the best-sealed enclosure can fail if the gasket material isn’t up to the challenge.

They say every failure is a step toward success, but we say that failure can be completely avoided by asking the right questions and having a clear understanding of your application's use case.

Lucky for you, we've condensed the important information we've learned over the years to help you make sure your enclosure is properly design right from the start.

From silicone to neoprene, each gasket material comes with trade-offs and will perform best in various situations, but how do you know which is best for your application and where should you start?

Have no fear, engineers! The Enclosure Institute™ has created a comprehensive guide on the Rogers website in the newest blog: Top 8 Sealing Material Options: How to Choose the Right One for Your Enclosure. 

This blog that breaks down the key differences in compression set resistance, temperature range, chemical compatibility, and cost across eight popular gasket options. With this guide and the Sealing Checklist Workbook (available exclusively to Enclosure Institute™ registrants), you're one step closer to sealing excellence.

NEMA (National Electrical Manufacturers Association), UL (Underwriters Laboratories), CSA (Canadian Standards Association), & IEC (International Electrotechnical Commission)—if you’ve ever felt overwhelmed by enclosure standards, our third blog from the Enclosure Institute™ is your go-to resource. 

With so many standards guiding performance, safety, and environmental protection, it can be difficult to know which ones truly matter for your application.  Whether you're designing for industrial environments, outdoor use, or specialized equipment, understanding these standards is critical—and easier than you think.

What exactly are enclosures—and why does sealing matter so much? In this foundational blog from the Enclosure Institute™, we break down the role of enclosures across a range of industries, from EV charging to medical devices. 

Sealing challenges can make or break the performance of an enclosure. That’s why Marian and Rogers Corporation have teamed up to launch the Enclosure Institute™ —a free educational series designed to help engineers tackle real-world sealing challenges with confidence. 

Silicone rubber materials and some plastic films have chemically inert and non-porous surfaces, which equates to low surface energy. This means they have a weak molecular bonding force making it difficult to create a bond with many pressure sensitive adhesives.

Per the Rogers Corporation Website, Rogers “BISCO^® HT-800 Medium Cellular Silicone offers the lightness of foam with the enhanced sealing capabilities of sponge rubber.” In this post, we'll dive a little deeper into this excellent material.

Silicone Rubber, a "Low Surface Energy" Elastomer - What Does This Mean?

Silicone is a high-performance elastomer with the ability to withstand extreme temperatures, both high and low. It also naturally repels, which makes it an excellent choice for a water seal or a moisture barrier. However, this also makes silicone tricky to bond to other surfaces.

Technological advances in properties of soft, flexible foam and elastomeric materials have continued. These thick, soft, flexible foams and elastomers like PORON foam, silicone foam, and more are ideal materials for sealing, gasketing and cushioning across many industries and applications.

They compress, form to irregular surfaces, bend, and flex within an application without damage or delamination, but from the perspective of the converter, these materials may also introduce challenges when trying to achieve the tight dimensional tolerances common in metal and plastic-molded parts.

We have published a new customer success story! In this story, the customer required a static seal for a navigation module that would be contained and used on the exterior of a recreational vehicle. The exterior navigation/infotainment module would be exposed to outdoor elements including extreme temperature swings, rain, wind, and dust. The gasket was required to reliably perform for the life expectancy of the class A RV. This could be more than 10 years! The customer came to Marian for a solution.

Video Demo: Thermal Resistivity and Conductivity of Silicone Foam

Thermal resistivity and thermal conductivity can be two very important physical features of foam materials for certain applications. Most devices containing electronic components must be designed to deal with heat in one way or another. Electronic circuitry operates most reliably at lower temperatures. High operating temperatures decrease the service life of the device or module. It is critical for designs to either conduct or isolate heat away from delicate components to ensure ideal operating temperatures.

When choosing a foam for a product design, one feature that should be considered is the compression set resistance of the foam. C-Set is one of the most important characteristics to consider, and this blog post answers three basic questions to explain why. 

Imagine going 65 mph in your vehicle while on a road trip. The road you are driving on is old, so your vehicle bobs up and down the many dips and divots, your speakers are loud and are causing your rearview mirror to vibrate, making it hard to see, and your moon roof has a roaring noise sneaking through the cracks.

These foul disturbances are examples of NVH, also known as Noise Vibration Harshness.

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. Neoprene, Polyethelyne, PORON Urethane, and BISCO Silicone are tested by being compressed for 48 hours.

Foam Material Compression

In the demonstration, you will see that certain foams depreciate as they take on impact over time, whereas other foams resist the compression set by returning to their original thickness. The material characteristic of being able to take a compression set, also called compression force defection, is extremely important in long-term sealing applications. The ability of the material to "push back" to fill in any potential gaps that would allow water or dust to pass through is critical. This makes such materials an excellent option for sealing gaskets. We wrote an entire blog post about compression force deflection, you can read it here: Compression Force Deflection in Foam Gaskets: A Critical Property

Compression Force Deflection

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.
