Flexible Solutions

Marian sales engineers are experts in designing high quality parts for any small, complex applications. Below, you will find links to two of our newest success stories that highlight laminated foam materials in two very different markets (LED lighting and automotive). In both stories, you will find that Marian's team of experts worked closely with customers to design a unique part and provided exceptional material recommendations to create a winning solution. Sales engineers must be strategic in choosing materials to ensure that they meet all requirements of the design.

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

Nitto TR Thermally Conductive Adhesive Tape Series

\Nitto’s TR series is a must-have for thermal and electronic applications. The TR series features a selection of double-coated tapes including TR-5912F and TR-5925F. 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:

PTFE membrane vents are made of hydrophobic microporous materials. This amazing PTFE material is designed to allow air to pass through while acting as a firm barrier to water and dust. 

Outdoor LED Lighting enclosures contain electronics assemblies that must be protected from the elements (rain, dirt, debris). As LED lights operate, they generate heat. As the enclosure heats up and cools down through the cycle of operation, the internal pressure changes. Without the ability to relieve this pressure, the enclosure can sustain damage and condensation can form. Both situations can be detrimental to the successful operation of the LED lighting system. 

PTFE membrane vents are a cost-effective way to protect your LED product. They keep dust and liquids out of the enclosure and relieve positive pressure or negative pressure within the enclosure.

What is a Light Shaping Diffuser?

Manufactured by Luminit - LSDs are light-diffusing films with patented holographic patterns embedded into optically clear polycarbonate or polyester sheets. These innovative materials homogenize and directionally shape light with high-transmission efficiency. Applications that could benefit from this technology are LED lighting, architectural lighting, recessed downlighting, signs & displays. Light-diffusing films are available with three types of angles: circular, elliptical, and linear.

• Circular spread a light source into a larger circular pattern, and for this reason, they are used widely across many industries. 
• Elliptical diffuser angles include 80 x 50, and 60 x 10. Common applications include hallways and specialty lighting that highlights a specific area. 
• Linear diffusers, typically 60 x 1 (60 along the width, and 1 along the length) are commonly used in applications where light must be diffused into a line (for example, a bar code scanner). 
   

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.

What is 3M™ FRB?  

It is thin flexible insulation made primarily of inorganic materials that is easily converted. The 3M™ FRB barrier material provides very high flammability and ignitability resistance, excellent arc and track resistance, good dielectric strength, and good thermal performance to safely contain electrical hazards. 

Outdoor LED lights are subject to a wide range of environmental elements and must be designed to withstand these hazards for the long life of LEDs. There are many components included in an outdoor lighting assembly, and one of the most important elements is a gasket. When choosing a material for an outdoor lighting gasket, it's imperative to understand the mechanics of an outdoor lighting fixture.
