As a result, the high performance acetal homopolymers, which are categorized by their viscosity, are well within the formaldehyde emission requirements of the leading automotive manufacturers, creating new opportunities for their adoption in automotive interior applications.
Testing by the SGS Institut Fresenius GmbH in Germany, in accordance with the VDA standard 275, confirms that all three low-emission grades of Delrin® are within the formaldehyde emission requirements of the leading automotive manufacturers.
The new low-emission grades are globally available in three basic melt flow series: Delrin® 100PE, 300PE and 500PE, with Delrin® 100PE being the most viscous. All three have been specially formulated with an additive to substantially reduce their release of formaldehyde during processing and use to levels which meet even the most stringent of emission requirements demanded by today’s leading automotive OEMs. Subsequent testing of low-emission Delrin®, carried out by SGS Institut Fresenius GmbH in Germany in accordance with the VDA (Verband der Automobilindustrie) standard 275, confirms the outgassing of formaldehyde from all three grades to be below 2 mg/kg.
As well as an extremely low volatile release, the new low-emission Delrin® grades provide the same high mechanical performance as the standard grades in terms of its strength, stiffness, creep and fatigue resistance and impact strength. “Our achievement in developing the first acetal homopolymer to meet the emission standards of all leading OEMs, without compromising mechanical performance, will open up new opportunities for the cost-effective replacement of existing materials in many automotive interior applications,” says Hans-Hermann Kirner, automotive car interior development manager at DuPont. “These include, for example, components for safety systems, door panels and seats, where its unique combination of properties can be of great benefit.”

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.
Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...
Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.
That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...
Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.
During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.
Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
