PLYMOUTH, Mich., Nov. 14, 2012 /PRNewswire/ --Freudenberg-NOK Sealing
Technologies (FNST) is showcasing a portfolio of products that enhance the
safety, durability and performance of electric vehicles today at the 2012
Battery Show in Novi, Mich.

FNST, one of the largest producers of elastomeric seals and custom molded
parts, is pursuing advanced electric vehicle technologies as part of its
commitment to sustainable products and processes. FNST is displaying a variety
of components at the show that leverage the expertise and products of its own
divisions and other Freudenberg companies including Freudenberg-NOK
Mechatronics and Freudenberg Nonwovens.

"We are working in collaboration with our customers to ensure that electric
vehicle technologies evolve to the next level of safety and reliability," said
Dr. Luis Lorenzo, vice president, Advanced Product Engineering, FNST. "One of
our key drivers is to develop alternative technological solutions that address
the functional requirements of the system and the cost effectiveness of
different approaches."

With operations in the Americas, Europe and Asia-Pacific markets, FNST can tap
a vast network of chemistry, design, product engineering and manufacturing
experts to provide solutions for the global vehicle electrification industry.
The company uses nearly two dozen polymer families and more than 2,000 raw
materials to provide premium battery protection technologies, including
battery pack gaskets, cell frame sealing, plug-and-seal technologies,
compensation elements and liquid detectors.

Among the technologies and products the company is displaying at The Battery

  oOverpressure Valve: For use in large-format lithium ion battery systems.
    The valve is designed to maintain its seal during normal pressure
    variations due to heating/cooling of the battery. The seal releases if
    internal battery pack pressure exceeds predetermined limit and prevents
    potential battery system damage.
  oHousing Gasket: A family of solutions for serial and prototype automotive
    lithium ion battery applications. Gaskets are re-openable for battery
    maintenance and optimized for sealing profile, homogeneous forces and
    tolerance compensation.
  oPlug & Seal: This elastomer-coated tube with a sealing and shock absorbing
    geometry works for applications across several industries. It accommodates
    a host of diameters, lengths, angles and end geometries, and can survive
    extremes of temperature, pressure and chemical environment. 
  oCell Frame Seal: A mounting structure for pouch type cells that both holds
    and stabilizes the cell. It also provides an additional sealing function
    for the sealed seam of the pouch, equalizes thickness tolerances of the
    cells, and provides additional mechanical fixing for electric connectors.
    The frame features passages for directing battery gasses in the case of a
    cell rupture.
  oBreathable Element: Breathable components produced from Freudenberg
    nonwoven materials that optimize the ability of the battery system to
    repel water, oil, and dirt contamination. The structure of the fabric
    creates a "deep filter" affect in the battery unit that ensures the
    exchange of gases even when exposed to environmental contaminants.
  oPressure Compensation: Freudenberg is developing several products to
    address the duty cycle pressure variations within a battery pack. Whether
    using a sealed pressure compensator or a hygroscopic filter unit, these
    products allow expansion and contraction of air within the battery pack
    without introducing additional moisture.

"FNST engineers work on-site with the auto manufacturers, so our teams have
been integrated into the vehicle electrification development process," said
Juergen Mall, market segment manager, E-Mobility, FNST. "We offer products
capable of performing over a broad range of temperatures and environments, and
our customers have come to rely on our expertise in areas like material
testing and product validation."

Freudenberg-NOK Sealing Technologies' advanced battery components and
technologies are on display at The Battery Show booth B504.
