A new foam grade, Teflon® FEP TE 9810, produces smaller, better dispersed and more homogenous voids compared to previous Teflon® foam grades for enhanced electrical properties in wires with melt extruded fluoropolymer insulations. Depending on the construction, this grade, Teflon® FEP TE 9810, has the ability to be self skinning, offering production of cost-effective, high-performance foam insulation for data cables.
New Teflon® FEP TE 9810 (left) produces smaller, better dispersed and more homogenous voids compared to previous Teflon® foam grades (right) for enhanced electrical properties in wires with melt extruded fluoropolymer insulations.
It enables the extrusion of all three sections of a skin-foam-skin construction – an inner-skin to ensure mechanical adhesion of the foam to the copper conductor, the foam itself and an outer, protective skin – in a single shot without the need for a second extruder and without the need for a multi-layer crosshead.
Meanwhile a new, licensable extrusion technology from DuPont incorporates air into the extruded Teflon® PTFE insulation for higher performance, low-loss data cables.
DuPont™ Teflon® and DuPont™ Tefzel® fluoropolymers are commonly used for their insulating capabilities under harsh environmental conditions including high temperatures up to 260oC. Whereas Teflon® PTFE, PFA and FEP are chosen for their thermal and chemical resistance in combination with electrical and low-friction properties, Tefzel® ETFE is chosen for its mechanical toughness, ease of processing and high-energy radiation resistance. Both Tefzel® and Teflon® have low dielectric constants and high volume resistivity as well as approved thermal class ratings (SAE, ISO) for wire insulation.
DuPont Fluoropolymer Solutions is a leading producer of fluoropolymer resins, additives, films, finishes and dispersions, PTFE (polytetrafluoro¬ethylene), PFA (perfluoroalkoxy), FEP (fluorinated ethylene propylene), ETFE (ethylene-tetrafluoroethylene) and PVF (polivinylfluoride), marketed under the registered trademarks DuPont™ Teflon®, DuPont™ Tefzel®, DuPont™ Tedlar® and DuPont™ Zonyl®. Major markets for these fluoropolymer products include the automotive, chemical processing, semiconductor, oil exploration, chemical handling, data communication, aerospace, electronics, housewares and building industries.
DuPont is a science-based products and services company. Founded in 1802, DuPont puts science to work by creating sustainable solutions essential to a better, safer, healthier life for people everywhere. Operating in more than 70 countries, DuPont offers a wide range of innovative products and services for markets including agriculture and food; building and construction; communications; and transportation.

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
