Selecting an adhesive for an enclosure gasket involves more than choosing a material based on a single peel-strength value. The adhesive must interact effectively with the foam or silicone while meeting performance requirements and fitting into the manufacturing process.
That is the focus of the first elective course from the [Enclosure Institute™](https://marianinc.com/enclosure-institute/), featuring 3M™ adhesive expertise and Rogers Corporation foam and silicone materials.
In this course, 3M application experts explore properties engineers should evaluate when selecting adhesives and walk through a bonding study they performed using their adhesives and various Rogers Corporation materials. The study examines how different adhesive and foam combinations behave during peel testing.
For Marian, the study highlights an important part of enclosure gasket design: **material selection, bonding, and converting should be considered together rather than as separate steps.**

### *Free Enclosure Design Training for Engineers *
If you haven't learned by now, enclosures are all around us. Many of your favorite everyday products (like your phone) are an enclosure that's designed to protect some kind of sensitive internal components. Because enclosures are so vital to our day-to-day life, it's extremely important that they're built to last, and that starts with a seal or gasket that's designed for the environment it will operate in and the conditions the enclosure will experience.
[Designing the right gasket comes with a variety of considerations far beyond just choosing a material, and that's what the Enclosure Institute™ is designed to help you navigate.](https://marianinc.com/enclosure-institute/)
Covering everything from material selection to design integration to [additional enclosure components like vents](https://blog.marianinc.com/blog/enclosure-venting), our hosts walk through the things you should keep in mind to build reliable, high-performance enclosures.

Selecting the right fabrication process for custom seals and gaskets starts with answering a few critical design-for-manufacturing (DFM) questions. By addressing these factors upfront, design engineers can avoid costly redesigns, speed up production, and ensure that their parts meet application requirements. At Marian, our engineers use these questions (and more) to create a fabrication plan tailored to each project.
This guide is presented by the Enclosure Institute™. For a deeper dive, explore the extended blog on the Rogers website, [*Top 8 Best Practices You Need to Know for Enclosure Die-Cut Gaskets*](https://www.rogerscorp.com/blog/2025/top-8-best-practices-you-need-to-know-for-enclosure-die-cut-gaskets), along with the[ video](https://youtu.be/C2R3murkcf8?si=3q5EoTBrMyEh2_r1) below hosted by Marian's own Phil Taylor and Jimmy Budd.
In these resources, you'll learn how starting with the right gasket design can optimize geometry to balance sealing force, fasteners, and load distribution. You'll also see why selecting manufacturing methods that align with production scale is critical for efficiency. Assembly features such as pull-tabs, locating holes, and specialized adhesives help streamline installation and minimize errors. Finally, packaging and delivery strategies play an often-overlooked role in protecting gasket integrity while making assembly faster and more reliable.

A seal’s true value isn’t in how it looks on day one, but in whether it still protects your enclosure years later under heat, moisture, and mechanical stress. This [Enclosure Institute™](https://marianinc.com/enclosure-institute/) article breaks down five core tests engineers can use to validate long-term gasket reliability: [compression set](https://blog.marianinc.com/blog/compression-set), stress relaxation, thermal cycling, chemical resistance, and IP ingress protection.

Designing a dependable enclosure seal isn’t just about picking or designing a [gasket](https://marianinc.com/gaskets-and-seals/), it’s about how that gasket behaves under compression, for the planned life of the device (hours, weeks, months, days, years, etc.), within your hardware’s mechanical limits. The latest article from the Enclosure Institute™ highlights four key factors that matter most: **gap spacing**, **compression force deflection (CFD)**, **material compressibility**, and **gasket width**.

Material selection related to seal performance is highly application specific. 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.

Not all sealing failures can be seen with the naked eye. Sometimes, subtle design oversights, improper installation, or even the application's environment if not planned for correctly can quietly undermine your enclosure’s performance.
There's a lot more than just material selection goes into designing a successful enclosure. In this case study, we highlight how Marian and Rogers Corporation teamed up to solve a moisture intrusion issue in a digital intercom system after the original gasket designed by a competitor allowed a leak to damage internal electrical components and, ultimately, caused the devices to fail.
The blog on the Rogers website, [What Good Sealing with the Right Partner Looks Like](https://rogerscorp.com/blog/2025/what-good-sealing-with-the-right-partner-looks-like), and the [video](https://www.youtube.com/watch?v=9MIjMIsvMMY) below walk through how the Marian team recommended materials that effectively sealed the touchscreen modules and also prevented the leaks that previously caused failure.

The Shore durometer (pictured right) is a scale for measuring the hardness of a material, such as rubber, plastic, thermal ** plastics (TPE), and rigid plastics. The term "durometer" is often used to describe a material's rating on the scale, for example “this material has a durometer of 60.” **
It's worth noting, there are a variety of durometer scales since elastomeric and plastic resins vary over a wider range than one scale can accommodate. **[Download our comparison chart](https://marianinc.com/durometer/)** to see how these scales overlap.
**Durometer hardness is one of many physical properties considered when selecting a material for a specific application. Beware of some common misconceptions. Durometer hardness is often inaccurately confused with the properties described below. **

## What is Electromagnetic Interference (EMI)?
EMI engages us through maneuvers such as radio transmitters, electric motors, power lines, fluorescent lights and computer circuits. Through these maneuvers, EMI generates electromagnetic disturbances, signals and emissions that cause undesired responses or degradation of performance in electrical and electronic equipment. This occurrence leads to system malfunctions and failures, which can threaten the performance of life support devices, military radio frequencies and aircraft flight controls – to name a few examples. Malfunctioning or failure of these types of systems, triggered by EMI, can be problematic, dangerous and life-threatening.

### Emblem Adhesive Tape Solutions
Think about all the things an emblem is exposed to each day during its lifetime. Depending on their use, emblems have to absorb the shock of a car driving over a pothole, the blow of a boat sailing over a wave, the turbulence of a plane flying through a jet stream, and even the vibrations of a running washing machine.
On top of all those external forces, in many situations, weather conditions are also a major factor. It's no easy task for an emblem to hold its bond or evade cracks during hot summers, cold winters, and severe weather storms.
After all an emblem endures, you would expect it to fall off quickly, which it will, unless you use industry leading emblem adhesive tapes to create a strong bond. Using the highest quality attachment materials ensures an emblem will maintain its longevity and hold a strong bond.

In this newly released [application story](https://marianinc.com/solution-center/), a global designer and manufacturer of critical intercommunication devices experienced a gasket failure allowing moisture to leak and compromise the internal components of their console. It's remarkable the amount of damage a single drop of water can do. Moisture often contains impurities and minerals that remain even after the water evaporates. Between the moisture and these remaining elements, the contamination can cause short circuits, corrosion, and mechanical problems. A malfunctioning device leads to recalls, replacements, and eventually a poor reputation. The company in this story did NOT want to deal with any of this.
The intercom console product was intended to be used in medical office settings. Cleanliness and sanitary standards were very important for the high-touch surface of this device. The console was sprayed with liquid cleaners often. The console housing required a reliable sealing gasket to keep moisture out.

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.

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](https://marianinc.com/materials/bisco-silicones/) 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](https://blog.marianinc.com/blog/compression-force-deflection), is extremely important in long-term [sealing](https://marianinc.com/gaskets-and-seals/)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.

## 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.

Ingress Protection (IP) Rating is a common international test method (IEC 60529) to rate enclosure protection from objects and liquids.
## Why is an IP Rating Important?
UL, CSA and CE Mark Standards often require certified products to hold a specific IP rating. Some examples of such products include IT equipment, laboratory equipment, electronic measurement equipment, plus anything claiming to be "dust tight" or "water-resistant", etc.
These terms indicate that a device is able to operate successfully in harsh environments such as potentially wet and dusty conditions. The IP rating scale provides a range of two numbers that indicate the level of protection provided.
##### The IP Rating looks like this: IPXX
1. The first number indicates protection from solid objects or materials
2. The second number indicates protection from liquids
For example, an enclosure that is rated IP54 is dust-protected. It will allow limited ingress of dust with the operation of the equipment for 2 to 8 hours. The enclosure is also protected against water splashed from all directions; limited water ingress permitted.
Before choosing materials for an IP-rated enclosure, it's important to understand the conditions and forces your application will encounter.

## What is Closed Cell EPDM Sponge?
Closed Cell EPDM Sponge is the third material we will explore in our blog series: **Foams for Low Clamping Force Seals**. EPDM stands for Ethylene Propylene Diene Monomer. "Closed Cell" describes the material at a microscopic level. The material is made with tiny bubbles that are inflated with gas, resulting in a closed cell structure that will not allowing moisture to pass through. This is what makes this material excellent for sealing and gasketing. EPDM is commonly used in the automotive and construction industries for various seals and gaskets due to its excellent environmental factors such as UV, Ozone and weathering. When comparing EPDM to Silicone, EPDM falls short when it comes to temperature resistance.
## **Features and Benefits of Closed Cell EPDM Sponge**
- Non-crystalline material. Contains no plasticizers that can migrate and lead to premature membrane failure.
- Can be formulated in a variety of combinations with other polymer modifiers.
- Performs well in the -40°F to 175°F temperature range.
- Excellent moisture resistance, does not absorb fluids easily
- Used in many applications that require water, UV, ozone, or indirect sunlight resistance (superior to neoprene in this regard)
- Does not meet UL flame rating without additives and will not withstand oil and fuels.

Adding a gasket to seal a device, whether it is keeping out dust, air, water, or something else, seems like it would be an easy part of the design. However, there are many material options available for most gasket applications. Choosing the best material may require some research. This is why we are starting a blog series outlining the features and benefits associated with the various foams that fit into this large subset of gasket material options: **Foams for Low Clamping Force Seals**
We are starting this series with **SILICONE FOAM.**

Rogers PORON® Microcellular Urethanes are tried and true materials for gaskets and seals. With excellent compression set resistance, this line of foam materials is easy to convert. They die-cut cleanly and securely while also adhering to a broad range of pressure-sensitive adhesives.
## UL-94 V-0 Flammability Rating
Product designs of the future are required to meet increasingly rigorous specifications with safety in mind. One of these requirements is often a UL-94 V-0 flammability rating. UL 94 is a plastics flammability standard released by Underwriters Laboratories (UL) The standard classifies plastics according to how they burn in various orientations and material thicknesses. The UL V-0 classification means that burning stops within 10 seconds on a verticle part allowing for drops of plastic that are not inflames.
Why is this important? More and more products across every industry include high-performing electronics. These electronic components generate heat. It is important that materials that are designed into these products meet specific material standards, such as UL94 V-0. In particular, the HEV market requires advanced sealing performance while meeting very rigorous specifications for passenger safety.

Rogers has recently released PORON® 4701-V0-M, which is specifically formulated to meet all requirements under UL94 for both V-0 and HBF flammability ratings.
