Posted by Lynn Zeheralis

January 31, 2018 8:46 AM

When selecting a foam for your application, have you every wondered if open or closed-cell foams are better? At Marian, we recommend materials based on a product’s application. This is certainly true when it comes to foam materials for use as a gasket. This means in order to recommend the best material, our first step is to understand the conditions, forces, stress and other requirements the gasket will experience in your end product.

Success Story: Silicone Gasket for Navigation Module

Posted by Katie Sullivan

November 8, 2017 12:22 PM

We have published a new customer success story! In this story, the customer required a static seal for a navigation module that would be contained and used on the exterior of a recreational vehicle. The exterior navigation/infotainment module would be exposed to outdoor elements including extreme temperature swings, rain, wind, and dust. The gasket was required to reliably perform for the life expectancy of the class A RV. This could be more than 10 years! The customer came to Marian for a solution.

Marian’s EMI Shielding Solutions Aid in Containment and Control

Posted by Andrew Bonar

June 19, 2017 8:15 AM

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.

EMI engages us through maneuvers such as: radio transmitters, electric motors, power lines, fluorescent lights and computer circuits. Through these maneuvers, EMI generates electromagnetic disturbances, signals and emissions that cause undesired responses or degradation of performance in electrical and electronic equipment. This occurrence leads to system malfunctions and failures, which can threaten the performance of life support devices, military radio frequencies and aircraft flight controls – to name a few examples. Malfunctioning or failure of these types of systems, triggered by EMI, can be problematic, dangerous and life-threatening.

Benefits for Plastic Injection Molders: Vendor Consolidation, Value Add Solutions

Why is it so imperative 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 Attachment Solutions: The Perfect Bond

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.

Antimicrobial Sealing Gasket - A New 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.

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.
