Antimicrobial Sealing Gasket - Application Story

Posted by Katie Sullivan

March 29, 2017 2:05 PM

In this newly released application story, 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.

Just about everything that has been engineered is likely to experience vibration. Unfortunately, it has been proven that vibration can be responsible for causing extreme damage to some applications. The source of vibration can come from impact, internal motors or external sources.

Video Demo: Thermal Resistivity and Conductivity of Silicone Foam

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. It is critical for designs to either conduct or isolate heat away from delicate components to ensure ideal operating temperatures.

3 Questions About Foam Compression Set Resistance

Posted by Katie Sullivan

January 18, 2017 4:34 PM

When choosing a foam for a product design, one feature that should be considered is the compression set resistance of the foam. C-Set is one of the most important characteristics to consider, and this blog post answers three basic questions to explain why.

Silicone elastomers are used in several diverse applications and industries because of their many unique properties. Silicone materials' attractive features include low compression set at elevated temperatures, flexibility at low temperatures, hydrophobic characteristics, high dielectric strength, low flammability, and can be food grade compliant. It is also lightweight yet high performing which is ideal for extreme environments.

Imagine going 65 mph in your vehicle while on a road trip. The road you are driving on is old, so your vehicle bobs up and down the many dips and divots, your speakers are loud and are causing your rearview mirror to vibrate, making it hard to see, and your moon roof has a roaring noise sneaking through the cracks.

These foul disturbances are examples of NVH, also known as Noise Vibration Harshness.

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.

Compression Force Deflection Demonstration of PORON and BISCO Foams

Posted by Katie Sullivan

July 7, 2016 8:30 AM

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
