Electronic devices are remaking our world. But they can also be dangerous when they’re not designed and manufactured with the end user in mind. Headlines about exploding laptops, hoverboards and smartphones in recent years are damaging to brands and put consumers at risk.

What’s causing these explosions? Look to the technological advancements that make these gadgets lighter, smaller, more powerful and portable. They produce more heat in smaller spaces compared to that of their predecessors. When devices lack proper heat and temperature management materials, the results can be catastrophic.

Then there’s the lithium-ion battery. Powerful, fast-charging and long-lasting, they also produce heat in the course of charging and discharging.

Excess heat degrades battery performance and battery life, or, worse, causes thermal runaway where the battery combusts or explodes. Prolonged exposure from high heat also damages components, shortening the life of the device.

Can tape make your electronic device safer, more reliable, longer lasting? Die-cutting adhesive tapes is the go-to for securing gaskets, panels, screens, batteries and other components in portable and wearable devices. However, there’s a plethora of tape products made with specially engineered foams, films and adhesives that can also safeguard sensitive components as well as the battery system.

That’s critical because devices get around. Whether you’re talking about laptops, smartwatches, tablets or the latest smartphone, batteries and electronic components demand protection from the hazards of normal use as well as rough handling.

Protective benefits of die-cut adhesive tape in electronics

• Reliably seal out dust and water.
• Absorb and cushion against shock, impact and vibration
• Heat dissipation to prevent overheating.

The need for protection: The future is portable and battery-powered

As our world becomes increasingly electrified, connected and portable, demand will continue to increase for lithium-ion battery systems.

Lithium-ion-powered electronic devices have forecasted 14.5% market growth between 2023 and 2032. Tablets and PCs are driving nearly one-third of global revenues for Li-ion powered electronics. Their leadership position is expected to remain over the coming decade, though smart, wearable devices will also contribute to demand.

Key considerations for die-cut tapes in electronics: Rugged protectiveness

Lithium-ion batteries deliver many sought-after properties in today’s portable devices. They’re lightweight, retain capacity after thousands of charging cycles, fast-charging and have a long lifespan.

To keep lithium-ion batteries safe and operable in electronic devices, two key considerations are top of mind:

• Thermal runaway: Heat or high impact that damages the highly flammable electrolytes within the battery cell can result in thermal runaway and combustion, setting the table for an explosive situation.
• Water and oxygen exposure: Lithium-ion batteries also require protection against moisture and oxygen. Cracked housing or total submersion in water can reduce performance and render the battery inoperable.

This gets to another important thing to consider about personal electronics: They’re personal.

Laptops, smart watches and smartphones are in near-constant contact with the end user. They’re worn, stored in pockets and transported in bags and backpacks, within reach 24/7. They’re subject to exposure to varying environmental conditions and temperature changes, accidental drops on hard surfaces and in water, and so on.

These devices demand enhanced protection of the battery against impact, vibration, heat and moisture. Tape selection around some of these protective properties can ensure the longevity and performance of these devices.

Considerations in choosing die-cut tapes for electronics

• Bonding strength
• Resistance to environmental conditions
• Conformity to curved or irregular surfaces
• Consistent adhesion for the life of the product
• Temperature resistance
• Vibration and shock absorption

Look for converters with preferred partnerships with multiple suppliers, demonstrating a high level of expertise with their products. At SRP, our longstanding partnerships with top brands like 3M^™ reflect the trust and confidence they have in our ability to represent their brand effectively.

Testing

Testing and prototyping are essential steps in the process, and a converter’s approach should facilitate rather than hinder these stages. Understanding the converter’s prototyping process, machining capabilities, and timelines for producing and shipping samples is vital to ensure a smooth and efficient development process.

Tolerance

Making the right call on the tolerance range of your part is essential to managing your costs. Whenever you die-cut foam and sponge material, some variability in the dimensions is expected between parts. The reason is when the machine cuts into the flexible material, it causes material compression, deflection and concavity. When you’re calculating specifications for soft components, you’ll want to adopt a tolerance range that’s probably wider than what you would normally choose for a hard component. But a skilled custom converter can calculate the optimal tolerance range for your gasket. This results in higher volumes of high-quality parts while minimizing material waste and production time.

Machining

Efficiency is at the core of lean manufacturing practices. Selecting the right machining process for specific materials is key. Different foams and sponges used in gasketing require tailored approaches to achieve the desired outcomes. By designing a production plan centered around efficiency, quality and waste reduction, a custom converter can help you optimize costs without compromising on the final product.

In the world of flexible material cutting, the choice between kiss cutting and die cutting can significantly impact the outcome of a project.

In the world of flexible material cutting, the choice between kiss cutting and die cutting can significantly impact the outcome of a project. Tolerance requirements, the efficiency of the method and material considerations all play a pivotal role in determining the most suitable method for machining custom parts from your chosen material.

In the following, we’ll outline the differences between kiss cutting and die cutting, along with some of the core factors that inform which machining method we choose for your part.

Kiss Cutting vs. Die Cutting: What’s the difference?

Die cutting is a term that’s often used to describe machining custom shapes from a material. The most common method uses a sharp steel die to cut shapes from the layers of foil, film, foam and adhesive. Kiss cutting is one of several die-cutting methods, and it’s often used to create a roll or sheet of peel-and-stick gaskets on a release liner.

Die Cutting

• Die cutting is a term that’s sometimes used interchangeably with through-cuts, which is when the die punctures through all layers of material, and meets the metal anvil.
• Flatbed die cutting is the most standard and oldest method for cutting identical shapes out of rolls and sheets of foam, tape and other flexible material.
• Much like a cookie cutter, the sharp-edged die or a steel rule is pressed directly into the material using a hydraulic press until it meets the metal anvil on the other side.
• After cutting, the part is completely separated from the remaining matrix, or waste material.

Kiss Cutting

• The counterpart to through-cuts, as the die does not pass through all layers of materials.
• The die is calibrated to end the cut at the very top layer of material that needs to remain uncut. For most kiss cuts, the uncut material would be the release liner. Once the cut is made, the matrix, or waste material, is cleared away, leaving the shapes on a liner.
• The most common machine method for kiss cutting is a rotary die press. But kiss cuts can also be achieved with a software-guided laser cutter, where the beam cuts down into the specified depth of the material.

Other considerations when choosing between die cutting and kiss cutting

There’s no one cutting method that suits every job. That’s why we plan production around what achieves the highest quality at the best value to you. Here are just some of the top considerations that factor into the decision of which machining method is best to produce your part.

Tolerance Requirements and Material Considerations

For parts that require a tailor fit with little deviation, flatbed die cutting will achieve the most precise dimensions with sharper edges, as the cuts are performed straight into the material.

Rotary die cuts made with a cylindrical die are less suited for thicker foams and sponge materials, particularly for jobs with narrow tolerance requirements. In these instances, flatbed die cutting can provide an alternative that produces the results you’re looking for. However, for thinner materials, rotary die cutting and laser cutting can yield tight tolerances.

Which Method Is Most Efficient?

Rotary die cutting can produce a higher output in less time than flatbed diet cutting, whether used to make kiss cuts or through cuts. (Rotary die cutting is capable of achieving both.) As the cylindrical die rolls over the material, it’s constantly producing shapes, making it ideal for high-volume jobs.

When used for making kiss cuts, rotary die cutting is a method that also makes assembly more efficient. When the gaskets and other types of adhesive-backed parts are presented on a release liner — whether on a sheet or a roll — the parts are easy to remove, easier to handle and require no sorting.

Flatbed die cutting, on the other hand, is more ideal for through cuts and kiss cutting thicker materials. It offers a rapid changeover, but the machining is slower than the rotary method as the hydraulic press stamps out one shape at a time.

When done well, kiss cutting is highly efficient and keeps material waste to a minimum. However, kiss cutting requires highly skilled machinists and ongoing monitoring for quality control and to make sure the die is achieving those precise cuts. Otherwise, cuts that are too shallow can ruin the parts on the liner.

By understanding these differences and considering the specific needs of each job, it’s important to make informed decisions that lead to the best quality results.

Adhesives can quite literally be the glue that holds operations together. Whether it’s tape, glue or a spray, adhesives can be found in nearly every industry due to their bonding strength and flexibility for numerous uses.

In the context of gaskets, using adhesives can prolong the life of the gasket and increase the effectiveness of the system as a whole. Recently, we wrote about The Top 5 Considerations For Custom Gasket Materials. Considerations for selecting the right adhesives for these gaskets follow much of the same thought process. Five considerations when choosing adhesives for custom gaskets, and why they matter.

1. Temperature

One of the first considerations to think about in selecting an adhesive for custom gaskets is to establish the temperature range it will be exposed to. There are two different aspects to focus on.

First, it is important to think about both the external and internal temperatures the adhesive will be experiencing on a day-to-day basis. This would include any potential outdoor weather extremes, as well as the internal temperature of what the adhesive, and by extension, the gasket, is keeping in.

Once that has been established, it is time to turn your attention to what type of adhesive you intend to use, and more specifically, what it is made of. There are a number of effective industrial adhesives on the market, but not all of them boast the same temperature tolerances. Selecting an adhesive that is effective for the entire potential temperature range it will be exposed to is crucial for your application.

2. Surface and substrate condition

To select a proper adhesive, considerations need to be made on the different substrates that will be attached to each other.

The first step is to analyze the properties of the substrate that may affect adhesion. Substrates can be rigid, flexible, smooth, coated with a certain chemical or material, and everything in between. These variables can all influence how well the adhesive performs.

Next, it’s important to account for the type of substrate itself. Metals, coppers, foams, polycarbonates, and a host of other materials can all be found in or around a gasket, so picking an adhesive that performs well with the surrounding materials it will encounter is an important aspect.

3. Method of application

Determining exactly how the adhesive will be applied to the custom gasket system can easily narrow down viable adhesive options.

If the adhesive will be applied by hand, there can be roadblocks to certain methods of application. Would it be feasible to use tape? Maybe a spray or glue is more practical? If the adhesive will be applied by an automatic process, maybe there is only a handful of feasible adhesive options during production.

Coming to terms with how the adhesive will be applied can narrow down choices based on practicality and ease of use alone.

4. Environment

Going almost hand-in-hand with temperature considerations when choosing a gasket adhesive are the environmental factors. Some of the most important to be aware of are:

• Chemical resistance: There is a possibility that the adhesives used in a gasket system could be exposed to the fluids or chemicals that the gasket will be holding in. Are they corrosive or toxic? Certain chemical resistances should be factored in when deciding on a proper adhesive if there is potential for exposure.
• UV: Consistent exposure to UV rays can easily compromise any exposed adhesives that do not have adequate UV resistance.
• Moisture: Moisture from either internal or external sources can come in contact with adhesives in a gasket system and could potentially compromise the seal.
• Function: Will the gasket be static throughout its lifetime? Or will it be exposed to movement and/or vibration? This will be an important factor when selecting a proper adhesive because if movement and vibration are present on a day-to-day basis, specific adhesives will need to be used.

5. Compressional forces

Compression set refers to a gasket’s ability to return to form after being exposed to a high compressional force. This is a crucial variable because, over time, gaskets that are exposed to force and have a minimal ability to return to form (otherwise referred to as a high compression set) can result in gaps or leaks.

The compression set of the gasket can greatly influence the type of adhesive used in the project. If the gasket will be exposed to high compressional forces, the chosen adhesive will need to be able to withstand the constant pressure and release of the system. Improper consideration on this front can result in the use of adhesives that quickly break down and compromise the gasket system.

We can help

Deciding on a proper adhesive for your custom gasket can be a complicated process. Whether you have questions about adhesives used in the gasket system or questions about the gasket itself, we can work with you to find a solution that fits your needs perfectly.

Neoprene is a material that can be found in a variety of industries and applications due to its versatility. It is especially common when it comes to custom gaskets and pressure-sensitive seals. In a previous article, we covered the different types and applications of neoprene gaskets, and now we will expand on why neoprene is classified as such a superior gasket material.

Solid Neoprene Vs. Neoprene Sponge

The first order of business when understanding neoprene and its applications is to differentiate between solid neoprene and neoprene sponge.

Solid neoprene is, as one can imagine, much more dense and compact than neoprene sponge. This increased density results in a form of neoprene that is more resistant to tears and cannot be compressed as easily, which results in a higher level of durability. Solid neoprene is a good option for use in applications that necessitate a higher level of strength or an increased rate of wear and tear.

Neoprene sponge is a foam-like version of neoprene, and the type of neoprene we specialize in here at SRP. This variation is much softer and easily compressible, making it a perfect option for uses in gaskets or seals that necessitate a complete seal. In addition to its sealing properties, neoprene sponge also excels at vibration and sound insulation.

Multiple resistances

Whether a project calls for solid neoprene or neoprene sponge, one of the biggest advantages of using neoprene is the material’s natural resistance to many different variables that the gasket may experience. Both forms exhibit very similar properties with only slight variations, which we will explore below.

Weather

Neoprene is extremely suitable for outdoor environments due to the material’s low oxidation rate. This means, of course, that water and other non-toxic liquids have very little effect on the material’s degradation in the long run.

In addition to water resistance, neoprene is also a high-rated material in its defense against sunlight and UV damage. In terms of pure temperature, neoprene can withstand temperatures as low as -50F and as high as 275F. While it is best to not push the material to its extremes, this temperature range shows that neoprene is an extremely versatile material for nearly any outdoor condition imaginable.

Compression

In addition to being extremely durable and tear-resistant, neoprene rubber performs very well under compression. Its natural elasticity makes it a perfect option as a gasket that experiences or will experience moving parts or compression forces.

Solid neoprene and neoprene sponge have slightly different compression rates, with solid neoprene being less compressible and neoprene sponge being more compressible. Therefore, if compression rate is a crucial variable to your application, it is important to make the distinction.

Chemical and oil

Neoprene naturally defects petroleum-based substances such as various oils and greases, and can even stand up against certain mixtures that include alcohol and different mixtures on the extreme ends of the PH scale.

Cushioning and protection

Expanding further on neoprene’s compression resistance, the material can easily be customized to fit perfectly between the needed components, and provides an extremely tight yet flexible seal. Usually, neoprene comes in at 40-80 on the durometer scale, meaning it is a great option to withstand compression forces and avoid any potential leaks or operational failures.

Once again, this is where solid neoprene and neoprene sponge differ slightly, with solid neoprene being less compressible.

We can help

Neoprene is a great option for gaskets due to its multiple resistances, the cushioning and protection it provides, the lightweight properties, and ease of use and installation.

When deciding on a custom gasket for your product, there are a number of factors that must be examined before placing an order. Any misstep in the design and consideration process, no matter how small, can result in severe problems and even system failures down the line.

To ensure a proper seal that stands up to any condition, a technical review of your chosen material is critical before making the final selection.

Below, we’ll dive into five key considerations for your custom gasket materials, and why they matter.

5 Variables to Consider Before Choosing a Gasket Material

It boils down to thinking about how the gasket will be used and the conditions it needs to stand up to.

1. Temperature

Temperature is one of the most important factors to consider when deciding on a custom gasket. There are two main areas to focus on. First, factor in both the internal and external temperatures the gasket will be experiencing. This, of course, not only includes things like the weather and any outdoor temperature extremes, but also the internal temperature and makeup of the device itself. What the gasket is keeping in or out, in other words.

Next, let your temperature findings guide you on what type of material the gasket will be made of. There are materials on the market that have a limited temperature range, or only excel on the high or low end of the temperature spectrum. Making sure you pick a gasket material that covers the entire temperature range it will be exposed to is crucial.

2. Environment

Factoring in environmental stressors does include temperature, but there are more noteworthy variables than just heat and cold. Some of the most important to be aware of are:

• Chemical resistance: Think about the fluids that the gasket will be holding in. Are they corrosive or toxic? Are there any external chemical risks? These factors can drastically impact the longevity of the gasket.
• UV: Consistent exposure to UV rays can quickly compromise a gasket.
• Moisture: Moisture from either internal or external sources can cause some gasket materials to corrode and deteriorate.
• Function: Will the gasket be static throughout its lifetime? Or will it be exposed to movement and/or vibration?

3. Compression set

Compression set refers to a gasket’s ability to return to form after being exposed to a high compressional force. This is a crucial variable because, over time, gaskets that are exposed to force and have a minimal ability to return to form (otherwise referred to as a high compression set) can result in gaps or leaks.

If your gasket will be exposed to compressional force, considering gasket materials that can easily return to form (or, those with a low compression set) is an important variable to reduce the possibility of operational failure.

4. Durometer

Simply put, the durometer reading is used to determine the hardness or softness of a given gasket. This number goes hand in hand with compression set, because the softer the material is, the higher compression set it has, and vice versa.

The durometer scale is referred to as a “shore” number, and ranges on a scale from 0-100. Softer gasket materials will register closer to “0”, while harder materials will register closer to “100”.

It is important to pick a gasket material that is soft enough to adequately create a seal between two joints, yet hard enough to be minimally affected by compressional force.

5. Industry and product standards

No matter what industry you are working in — be it automotive, aerospace, military, pharmaceutical or otherwise — there are standards and requirements for the material of your gasket. Making sure you decide on a gasket that adequately fits your project needs, while also remaining in compliance with your industry, can be a tricky process.
