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.

There are many EMI shielding materials to choose from when determining how to effectively control EMI within an electronic device. In this post, we focus on die-cut foil tapes for EMI shielding. Foil tapes with conductive adhesive provide effective shielding properties as the thin foil layer ensures good electrical contact with the component surface. Let's take a look deeper at EMI and why foil tapes may be the best-suited material for your application.
What is EMI and Why is it Important?
Electromagnetic interference is unwanted “noise” or interference in an electrical path or circuit caused by an outside source. EMI can be caused by natural or man-made sources and can cause electronics to malfunction or to completely stop working. Therefore, EMI shielding and grounding components are important pieces in the design of electronic devices.

Double coated foam tapes are a type of adhesive tape that is made of tacky adhesive coated on both sides of a foam core or carrier. DC foam tapes fill gaps and distribute stress uniformly over the bonded area. Depending on the specific tape, the result is a bond line that seals, cushions, and damps vibration, resists impact, withstands a wide temperature range, and provides good insulating qualities. Double-coated foam tapes are strong and durable.

Thermal Runaway Propagation Prevention with Thermal Barrier Materials
Hybrid and battery electric vehicles that use lithium-ion cells require that these cells are maintained at specific ambient temperatures. "Thermal runaway" occurs as a result of the rapid rise in temperature within one of the battery cells. One of the greatest challenges for battery design engineers is to manage heat. For this reason, batteries are designed with thermal management systems, like thermal gap pads and thermally conductive tapes, that provide different levels of protection, including cell-to-cell, module-to-module, and pack level.
Marian provides custom flexible die cut solutions that are incorporated into battery design at the cell, module and pack level to aid with thermal management. These die-cut parts are made with high temperature resistant materials (also known as flame barrier materials) that are designed to offer thermal insulation to delay the onset of thermal runaway.

The majority of the die-cut parts manufactured by Marian include a Pressure Sensitive Adhesive Tape (PSA). PSA tape is thin flexible material coated with a thin layer of adhesive, making one or both sides sticky. By producing billions of adhesive-backed parts each year, it’s safe to say Marian has a lot of experience with this sticky stuff!
PSA tapes can come in various constructions, which offer different functionalities based on your application. There are double-coated tapes, single-coated tapes, and adhesive transfer tapes. Check out our blog post, Pressure Sensitive Adhesive Tape Constructions, to learn more about different tape constructions.
The first step is choosing the best PSA type and construction for your application (by the way, we can help with this! Download our ebook: 4 Questions to Ask Yourself when Selecting a PSA). An equally important step when utilizing a PSA in the assembly of your product, is the proper storage and proper application of the PSA. Missteps when storing and applying your PSA can lead to product failure.

Pull-tabs, extended liners and split liners are assembly aids. They make the process of removing the liner from a die-cut adhesive part much easier. When you work with Marian, we keep your manufacturing and assembly process in mind as we develop the solution. Our goal is to make things easier for you, saving you labor and time spent during assembly, placement, or manufacturing. Once we understand how our part will be assembled into your product, we can often offer a variety of solutions. These solutions can include (but are not limited to):
- Part orientation / spacing on the liner
- Final packaging:
- Kiss-cut to a liner and wound onto a roll
- Singulated parts
- Kiss-cut to sheets
- Perforated liner
- Modifications to the carrier liner for fixturing
- Pull-tabs, extended liners, split liners
In this blog post, we are going to focus on pull-tabs, extended liners, and split liners.

Thermal gap pads are one common type of thermal management materials and are utilized in electronic devices within the interface, or gap, between a heat generating component and a heat sink. The heat sink or cooling plate is designed to conduct heat away from the heat generating component to keep it cool and running safely.
According to Parker Chomerics Thermal Management Engineering Handbook, the typical contact area between most semiconductors and heat sinks can be made up of 90% air voids! We also know that air is about 200 times less conductive than a 5 W/mK thermal interface pad. This is where the thermal gap pad comes in.
Thermal gap pads are made of soft polymer that flows into the air gaps in the interface to aid in the more efficient and effective conduction of heat.

Improvements are being made to the lithium-ion batteries used in electric vehicles. Auto makers are developing more powerful lithium-ion batteries that have increased range and charge more rapidly. Along with these improvements, enhancing safety has becoming increasingly urgent for electric vehicle development.
As mentioned in our previous blog post, 11 Considerations when Selecting Thermal Interface Materials for Electric Vehicle Li-Ion Batteries, Li-ion batteries produce a significant amount of heat while in use and while charging. Along with the use of thermal management materials, placing protective engineered flame-retardant insulating materials between the components of the battery cell, module, and pack can offer additional thermal and electrical insulating protection. However, adding such materials can be challenging due to space and weight constraints.
In this post, we outline four materials that can enhance the safety of lithium-ion batteries used in electric vehicles. Some shared characteristics of these four materials are listed below.
- ultra-thin
- lightweight
- electrically and thermally insulating
- flame retardant
- can be die-cut and laminated with PSA

Paint masking can be a tedious process. When masking an area with precision and over-masking is unacceptable, custom die-cut masks prove to be the best solution. Die-cut masks are pre-cut pieces of masking tape that are made to the exact size and shape of the surface area in need of masking. This video shows a direct comparison of the masking process with strips/knife versus masking with a die-cut part with a split liner. You'll see this demonstration proves that masking with a custom die-cut is easier, faster, more accurate, and safer.

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 to see how these scales overlap.
Durometer hardness is one of many physical properties considered when selecting a material for a specific application.
