Adhesive selection can be challenging, and it’s even more difficult in applications that generate heat like electronics, batteries, and more where the risk of fire is present. You can find many flame-retardant pressure sensitive adhesives on the market, but flame-retardant doesn’t necessarily mean halogen-free. So, if there are available options, why should you consider choosing a halogen-free tape?

Keep reading to see what classifies an adhesive as halogen-free, why you might consider a halogen-free tape in your next heat-generating application and learn more about some of the many halogen-free tapes available from tesa^®.

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, and the video below walk through how the Marian team recommended materials that effectively sealed the touchscreen modules and also prevented the leaks that previously caused failure.

Digital displays are an integral part of modern vehicle dashboards, household appliances, consumer electronics, and more. In applications like thermostats, cell phones, smart watches, and vehicles, displays allow a simplified, interactive experience for users. To make these digital display assemblies, manufacturers require a variety of die-cut components that, when combined, come together to make an impressive display that provides extreme clarity and a user-friendly experience, which we highlight below.

In the fast-paced world, electronics are now integrated into almost every aspect of human life. Solutions ensuring optimal performance and longevity are necessary to meet consumers’ expectations. Many converted electronic components are made using materials that address various challenges faced by electronics applications, including thermal management, electromagnetic interference (EMI), surface protection, and more.

As interest from consumers to purchase products that are sustainably sourced and manufactured grows, companies around the globe are modifying their practices to include measures and policies to reduce their carbon footprint.

Combining Intricate Laminations to Create Multifunctional Parts

Electric vehicles (EVs) continue to experience a sharp growth trajectory, generating process advancements and additional application requirements and needs. Marian has developed improved solutions to meet the industry’s most critical necessities for battery longevity, performance, and passenger safety.

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.

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.

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.

IP Rated Enclosures: Venting Solutions

Sensors, controllers, and other electronic elements are being integrated into devices across virtually every industry. Many of these products are made for use in conditions where they may be exposed to extreme temperatures, rain, wind, dust, and moisture. (See application story about "smart" shipping pallets linked at the bottom of this post.) Designing such products requires that the container or enclosure holding the electronic components be completely sealed. Exposure to harsh elements could cause a product failure. 

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 struggle between the world and electromagnetic interference (EMI) is endless. EMI consistently attempts to sabotage our most critical technologies in the aerospace, mass transit, medical, and military industries.

Why is it so important that plastic injection molding companies provide value added services and secondary manufacturing services to their customers after molding their parts?

The answer is easy! Many end-customers of plastic injection molders are looking for vendor consolidation and supply chain simplification. They want to cut out and skip steps in their supply chain, sequentially helping to reduce costs and save time.

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.

These tapes exhibit powerful adhesion and thermal conductivity which accounts for their strength and reliability. Nitto recommends replacing the use of a screw-in an LED or other thermal applications with these thermally conductive adhesives for the best performance. Using the tape method offers superior thermal conductivity performance, and can extend the life of your LED, compared to using the screw method. 

Pressure sensitive adhesives (PSAs) are defined as any transfer, single coated, or double coated bonding tapes that only require pressure in order to completely adhere and bond to a surface. One important component that single coated tapes and double coated tapes share is their requirement to have a tape carrier. Depending on the type of tape you're using, the carrier serves different purposes.

3M™ has released a series of new attachment tapes for the automotive market with a goal to strengthen their offering in low VOC thin attachment tapes where increasing regulation and OEM/Tier suppliers are driving a larger need. VOC refers to the amount of volatile organic compounds. VOCs are inherently present in newly produced components for auto interiors, which are made of materials like rubber, plastic, foam, and leather. They contain additives that are especially volatile when vehicles are new.  Automobile manufacturers have become increasingly focused on the air quality of the interior, making a push toward lower VOC emissions, which makes low VOC tapes appealing. 

Here are 10 things you should know about 3M Low VOC Tapes:

The use of pressure sensitive adhesives is growing rapidly in the industrial manufacturing market. The advantages of using adhesive tapes are clear:  they are lightweight, clean, and safe. Marian has the converting capabilities to produce die cut tapes, which are cut to specific dimensions. Tapes are often combined with, or laminated to other materials such as foam or film to create a more dynamic die cut part.

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.  

Die-cut foam tape can be an excellent choice for your bonding application. With help from our friends at 3M, here are the top 10 reasons to choose acrylic foam tape versus mechanical fasteners. 

What There is to Know About Tape Primers 

3M recently launched two high-performance acrylic foam tape lines for the automotive market: EX4500 and PX5000.

3M tape primers are applied to the bonding surface prior to the application of the tape. Primers are often made of chemicals like isopropyl alcohol and promote and increase adhesion.

Zoned adhesive lamination describes the process of laminating a selective pattern of PSA (pressure-sensitive adhesive) onto another material to achieve a specific function. Simply said, this process involves manufacturing a multi-layer part in which the layers have different geometries. This occurs through a process of conversion - laminating materials together, precisely die cutting those materials, and pulling away from the unwanted PSA material from the finished part.  

Zoned adhesive patterns are often required for filter and venting die-cut components and often include a PSA layer. As you can see in this image, the mesh is cut into a circle while the adhesive is cut into a ring, which allows air and sound to flow through the center of the mesh.  

Tape for Permanent Mounting AND/OR Temporary Fixation. Is that possible!? 

How can an adhesive tape have an extremely high bonding strength while also being easily removable?  Seems improbable, right?  Let us introduce you to the tesa® Bond & Detach series of stretch release tapes.  

When selecting a pressure sensitive adhesive for your die-cut tape, there are many characteristics to consider. Tapes have varying degrees and even different varieties of peel strength. Peel strength, tensile strength, and shear strength of a tape are each measured utilizing specific tests, as shown in the video demonstrations below.

When choosing a PSA for your application, you will want to consider the different types of adhesion strength and determine which are the most important to your application’s proper function.  

Over the years, the use of pressure sensitive adhesive tape has grown rapidly in manufacturing and practically all other industries. This means a growing number of design engineers are learning about and sourcing pressure sensitive adhesives for their application. Adhesive selection is an involved process is to determine the surface energy of the two substrates that are being bonded. 

WHAT IS SURFACE ENERGY?

Are you designing a product or working on an application that requires a double-sided tape or transfer adhesive? There are infinite amounts of tape materials available with different adhesive types, carrier types, and constructions. We understand that it can be overwhelming to look through numerous catalogs of pressure-sensitive adhesive products to determine which one will work best in your application. Therefore, we have come up with a checklist of only 4 questions that will help you narrow down the most important factors in your decision. Some factors to start with when selecting a PSA material include:

• Required function of the PSA (i.e.: bonding, sealing, skin contact)
• Substrate surface energy (is the bonding surface high surface energy, low surface energy?)
• What type of stress will be exerted on the PSA? (shear stress, pluck stress?)
• What other conditions will the PSA be exposed to? (high/low temperatures, solvent & liquid exposure, visual appearance)
