Our valued material supplier, Rogers Corporation, has released PORON® EVExtend 4701-43RL polyurethane foam material. This is an ideal battery pad material for EV/HEV li-ion pouch cell batteries.

Currently, lithium-ion (li-ion) batteries are the most common type of battery used to power electric vehicles. Today's market is demanding that batteries charge faster and last longer. Because li-ion batteries produce significant heat when in use and charging, thermal management is critical.  Excessive heat can cause irreparable damage to the battery. 

Technological advances in properties of soft, flexible foam and elastomeric materials have continued to advance. These thick, soft, flexible foams and elastomers are ideal materials for sealing, gasketing and cushioning across many industries and applications. They compress, form to irregular surfaces, bend, and flex within an application without damage or de-lamination, but from the perspective of the die cutter, may also introduce challenges when trying to achieve the tight dimensional tolerances common in metal and plastic-molded parts.

We have published a new 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 perform as designed for the life expectancy of the class A RV.  This can be more than 10 years!  

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.  

Thermal resistivity and thermal conductivity can be two very important physical features of foam materials to certain applications. Most devices containing electronics 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.

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. 

We believe that true stories can tell you more than any fluffy Marketing Materials that we create.  That is why we are sharing two new Case Studies in this blog post.  Both Case Studies explore die-cut solutions that Marian provided to Medical Device Companies.  In this Industry, component quality and reliability is critical.  Additionally, assembly efficiency and cost savings are important to the success of the business.  In these case studies, you will see that Marian is well equipped and prepared to meet the stringent requirements demanded by products in the Medical Device Industry.  Enjoy!  

As medical device designs trend toward including cutting-edge electronics technology and wireless capabilities, EMC is a growing factor in device design.  

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.  Here are 10 things you should know about them:
