Highlights of the DuPont exhibit, to be found at D1 in Ravel Hall, include the Surlyn® Design Center, which aims to provide brand owners and designers with the inspiration and practical advice required to achieve new and innovative designs in Surlyn® for their packaging. New technologies portrayed at the stand will include Surlyn® 3D overmolding and new techniques for the cost-effective production of effects such as marble and natural textures.

Eye-catching visual effects in Surlyn®: The cap of the new ‘Oriens’ fragrance from Van Cleef & Arpels mimics the appearance of a tourmaline gem thanks to the clarity and magnifying effect of the DuPont material.
A spectrum of colors
The colorful effects and luxurious appearance achievable with caps molded from Surlyn® is perhaps best illustrated by the cap of the new ‘Oriens’ fragrance from Van Cleef & Arpels, a brand of Inter Parfum, Inc. The bottle’s designer, Joël Desgrippes, modeled its appearance on the design of a ring from the company’s own jewelry collection, with the faceted, Surlyn® cap mimicking the pink-orange-green spectrum of the tourmaline gem set within the ring. Key to achieving this effect is the clarity and magnifying effect of the DuPont material. The three different colors lacquered on the surface of the Surlyn® are reflected by the metallic insert set deep within the thick-molded cap, producing a shimmering sense of depth and luxury. Further criteria for the selection of Surlyn® include the material’s high compatibility with the ingredients contained within the fragrance, as well as the possibility to integrate a very small injection gate which could be easily hidden behind the one of the leaves in the cap’s design. “The cap is a genuinely beautiful creation and we are proud to have worked with the molder Lisi Cosmetics on its development. Thanks to their material knowledge and command of the injection molding process, we have created a cap of extreme quality,” confirms Marion Trossat, packaging developer at Inter Parfum.
New effects in Surlyn®
Among the many eye-catching special effects achievable in Surlyn®, to be presented at Luxe Pack 2010, is the creation of caps and jars with a marble-like appearance. The patented technology behind this effect is the inclusion of a different-colored nylon 6 in the Surlyn® resin, as Prosper Zufferey processing expert at DuPont, explains. “The difference in melt temperatures between Surlyn® and nylon 6 allows us to use different colors to create colored veins within the injection molded part.” Further depth can be added by creating a glass marble effect, achieved by co-injection molding a transparent Surlyn® outer shell with the Surlyn®/nylon compound.
The production of molded packaging elements in Surlyn® with new, highly-creative textures such as leather or wood provides a further example of the design freedom achievable with Surlyn®. The desired texture for the finished part is finely laser-engraved within the tool cavity and can be precisely replicated by Surlyn® from the tool, without any need for secondary operations, thanks to the material’s easy flow characteristics and low rate of shrinkage.
DuPont™ Selar® PA – a high barrier resin for cosmetic containers
Luxe Pack 2010 will also mark the commercial introduction of two new grades of Selar® PA amorphous nylon, Selar® PA 3426R and Selar® PA 7003, targeted for use as a high barrier resin in cosmetic containers such as those for nail polish and waterproof mascara. Cosmetics such as these can require their containers to provide high barrier performance in terms of water vapor, oxygen and carbon dioxide, as well as high chemical resistance, scratch resistance and gloss effect. New impact-modified Selar® PA 7003, for instance, combines all of these attributes with an increase in impact resistant versus incumbent materials. Accordingly, the potential benefits for container manufacturers adopting the new resins are a reduction in wall thickness and production costs.

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.
Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
