In this article, Ken Kozicki from High Performance Foams, shares the real cost of a gasket or seal, which has a much bigger impact than the actual cost of the item itself … especially in a rail car:

More often than not, there is a significant amount of emphasis and evaluation placed upon the selection of the materials used within the more prominent features of the interiors. This includes composite materials for side wall and ceiling liners, seat cushion foams and upholstery, and flooring structures, to name a few.

…what is frequently ignored is the hidden value and importance of the multitude of gaskets and seals that protect, preserve and actually integrate the various interior systems and modules together. While one of the main functions of a gasket or seal is to keep moisture or water from leaking into an undesired place, there are also many other considerations that should go into gasket selection. A great deal of engineering effort is spent determining vibration isolation and damping, acoustic blocking and absorption, as well as contribution to EMI/RFI protection and conformance to flame, smoke and toxicity requirements.

Ken answers questions like:

  • Does the quality of material that seals two expensive wall panels really make a difference?
  • Do you know what a compression set is?
  • Do you know what degradation of force deflection is, and how it impacts a seal?

Introducing the L3 Première: Reduce vibration in rail flooring

The High Performance Foams team recently launched a new product in its BISCO® line of silicone foams called the L3 Première, specifically designed for rail applications.

Employing breakthrough technology, the new L3 Première improves the passenger experience by reducing vibration in flooring constructions. Utilizing L3 Première isolation pads enables a smoother, more comfortable passenger ride especially in high speed rail applications.

Under extreme conditions for temperature and load, L3 Première maintains performance by retaining thickness and performance with low stress relaxation. 20 percent lighter than its L3 predecessor, the durable, long last-lasting material greatly resists compression set reducing the need for costly refurbishments over a railway cabin vehicle’s operational lifespan.

There has been lots of discussion of how manufacturing is becoming a thing of the past in the United States. Well, we were happy to read in this New York Times article “Does America Need Manufacturing” that there is a shift happening in area of advanced battery technology to help make advancements in clean energy technology.   Not only has the government been providing stimulus money to help drive these efforts, but it’s also promising to help job creation in this tough economy.  Clean energy technology is one of our megatrends that we track, and are actively working on developing new products in this area.

The article notes:

In 2009, the U.S. made less than 2 percent of the world’s lithium-ion batteries. By 2015, the Department of Energy projects that, thanks mostly to the government’s recent largess, the United States will have the capacity to produce 40 percent of them. Whichever country figures out how to lead in the production of lithium-ion batteries will be well positioned to capture “a large piece of the world’s future economic prosperity,” says Arun Majumdar, the head of the Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E). The batteries, he stressed, are essential to the future of the global-transportation business and to a variety of clean-energy industries.

This is good news, we hope the trend continues in this direction.  We are doing our part in advancing this technology.  We recently launched our RO-LINX® PowerCircuit™ Busbars that enable the effective distribution of high voltages and large currents in power electronic modules for HEVs and EVs, while minimizing physical and thermal constraints. On another side, we are working to create more effective lithium ion battery pack assemblies and enclosures using silicone and urethane foams to protect this sensitive technology from harsh environments, improve durability and help extend battery life and capacity which is a huge issue when it comes to all types of EVs.

One thing is for certain, this is a rapidly moving technology that is evolving very quickly. Lithium ion batteries are where it’s at today, but we anticipate there are more advanced battery technologies that are in development now that could become a game changer in clean technology. At Rogers, we’ll continue to be committed to staying on top of clean technology trends and will be developing new products to help respond and meet consumer demands for even better HEV and EV solutions.
