WEINHEIM, Germany, Nov. 14, 2013 /PRNewswire/ --Seal manufacturer Freudenberg
Sealing Technologies is launching an innovation offensive to respond to the
industrial challenges of the 21st Century. The issues of mobility, renewable
energy, dwindling raw materials and demographic change have emerged as
megatrends. Freudenberg Sealing Technologies has decades of experience in
materials development and can offer solutions to these pressing problems.
"As the global market and technology leader, we feel it is our duty to cope
with the effects of these global megatrends with forward-looking research and
innovative products," Claus Mohlenkamp, CEO of Freudenberg Sealing
Technologies, said today at a press conference in Mannheim, Germany.
More than 40 new products and innovations have been presented at the company's
accompanying Trend Forum at the Rosengarten Congress Center in Mannheim.
State-of-the-art sealing technology harbors substantial capacity to make
valuable contributions to sustainable mobility in cars, air and rail
transport, and shipping. It is always important to minimize friction, to
optimize combustion processes and reduce weight, thus cutting the energy
consumption and emissions of the means of transportation. In this way,
Freudenberg's Low Emission Sealing Solutions, bundled into its 'LESS'
package, are already pointing the way to the mobility of the future.
The gas-lubricated mechanical seal Levitex is the best example of this. It
comes extremely close to the vision of a friction-free seal. The slide ring
interacts with a counter-ring to form a cushion of air, resulting in 90
percent less frictional loss than a conventional crankshaft seal ring. This
reduces CO emissions by 0.5 to 1 gram during driving. And that's not the
only benefit: longer operating times are possible due to decreased wear.
Downsizing and intelligent engine management systems are raising the internal
combustion engine to a new level of efficiency – but they are also creating
new challenges for low-friction and heat-resistant seals. As they do so, even
the smallest improvements count when it comes to achieving global objectives.
Freudenberg Sealing Technologies materials expertise, built up over decades,
is the breeding ground for seal technology. In this field, it is the mixture
that makes the difference, together with a sophisticated design. The
Weinheim-based company produces high-quality basic materials for its seals in
its own mixing plants. Several hundred employees in materials engineering and
the plants lay the foundation for the high quality, functionality and
long-term functional stability of the seals.
The new polyurethane standard material, produced in Schwalmstadt, is one of
the latest examples. The new generation of polyurethane was devised especially
for a broad spectrum of use without displaying weaknesses in a particular area
of application. The material is much more resistant to water and withstands
major temperature swings. The application range is between -40 and +120
degrees Celsius. This was made possible by the targeted modification of the PU
components responsible for temperature characteristics -- without having to
compromise on the remaining characteristics. In this way, manufacturers no
longer have to store different versions of components such as hydraulic
The new polyurethane generation is designed as much for challenges in the
arctic as for tropical climatic zones. The material is also a genuine
high-performance material when it comes to pressure. In a comparison test at
40 MPa and 100 degrees Celsius with different extrusion gaps, seals made from
the material show no appreciable signs of wear. Their tensile strength also
surpasses the current possibilities by far. It is about 35 percent greater
than other materials.
The company's materials expertise is an important factor in other fields as
well. In wind power systems, for example, it is a huge challenge to replace a
leaking seal 100 meters in the air in stormy seas. To eliminate the need for
this, Freudenberg Sealing Technologies developed seal materials specifically
geared to the stringent requirements of wind turbine manufacturers. Salty air,
ozone, weather and temperature extremes, aggressive lubricants – the seals
stand up to them all. Tests and trial runs are impossible for seals up to
three and one-half meters in diameter. This makes reliable in-house
simulations and test processes all the more important. FEM calculations are
one example. So we develop materials for seals that combine extraordinarily
high reliability and functional stability with a long operating life.
The company's Ventoguard materials series, which was especially developed for
seal profiles in wind turbines, incorporates the premium quality to meet the
highest possible demands. Sealing the main bearing on a wind turbine's rotor
shaft poses a particular challenge. The newly developed Merkel Radiamatic R 55
has an integrated deflector lip to protect against environmental influences.
It makes a second seal – which has been needed until now – superfluous. Along
with cost-savings, the small installation space required for the solution is
an argument in its favor from the standpoint of equipment manufacturers and
Food production has to nearly double by 2050 to provide enough food for a
growing global population. This calls for greater automation with long
operating times as well as the high flexibility required for rapid product
changes.This is precisely what sealing solutions from Freudenberg Sealing
Technologies make possible. Freudenberg's external-sealing Hygienic Usit
washers are one example. There is always the threat that a highly undesirable
medium for germs may be forming under nuts and hexagonal screws. This is
prevented by Hygienic Usit washers combined with precisely calibrated special
screws and cap nuts. They provide maximum safety in food production and
minimize the operator's service and maintenance work. The sealing material
Fluoroprene XP is another example of Freudenberg Sealing Technologies'
innovative power in the food sector. It is an all-purpose weapon against the
carry-over of flavors during product changes and the adulteration of taste in
food production. That means a Pilsner tastes like a Pilsner and the soda
produced later really tastes like a soda.
