The use of halogenated flame retardants in plastics is steadily declining because they are volatile, pose an environmental risk and are difficult to recycle. Microcapsules, fibers and melamine resin foams represent some of the chief alternatives.
As successfully as the endless variety of plastics have established themselves on the market, these multifaceted materials show another face when it comes to fire. They melt and feed the flames like the petroleum from which they were ultimately produced. As a preventative measure, a variety of flame retardants are added to plastics, yet this introduces a number of problems. Additives often alter the mechanical properties and electrical insulating effect of plastics. Especially brominated and chlorinated additives migrate through the material and can damage metal and electronic components. Moreover, they represent a health risk and interfere with the recycling process. Yet fire safety regulations require the use of flame retardants.
The Fraunhofer Institute for Applied Polymer Research IAP is developing combustion-resistant and self-extinguishing plastics. Last November members of the working group, directed by Dr. Gerald Rafler, received the Friedrichs Prize for new technologies, along with 15,000 Euro in prize money, for their innovations and development of new materials. The prize is awarded by the German Federation of Industrial Cooperative Research Associations "Otto von Guericke" AiF. The new materials are already being tested and prepared for market introduction by the Austrian company Agrolinz Melamin GmbH.

Optical quantum computers can revolutionize computer technology. A team of researchers led by scientists from Münster University and KIT now succeeded in putting a quantum optical experimental set-up onto a chip. In doing so, they have met one of the requirements for making it possible to use photonic circuits for optical quantum computers.
Optical quantum computers are what people are pinning their hopes on for tomorrow’s computer technology – whether for tap-proof data encryption, ultrafast...
The Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has been developing various applications for OLED microdisplays based on organic semiconductors. By integrating the capabilities of an image sensor directly into the microdisplay, eye movements can be recorded by the smart glasses and utilized for guidance and control functions, as one example. The new design will be debuted at Augmented World Expo Europe (AWE) in Berlin at Booth B25, October 18th – 19th.
“Augmented-reality” and “wearables” have become terms we encounter almost daily. Both can make daily life a little simpler and provide valuable assistance for...
With the help of artificial intelligence, chemists from the University of Basel in Switzerland have computed the characteristics of about two million crystals made up of four chemical elements. The researchers were able to identify 90 previously unknown thermodynamically stable crystals that can be regarded as new materials. They report on their findings in the scientific journal Physical Review Letters.

For the first time, Fraunhofer IKTS shows additively manufactured hardmetal tools at WorldPM 2016 in Hamburg. Mechanical, chemical as well as a high heat resistance and extreme hardness are required from tools that are used in mechanical and automotive engineering or in plastics and building materials industry. Researchers at the Fraunhofer Institute for Ceramic Technologies and Systems IKTS in Dresden managed the production of complex hardmetal tools via 3D printing in a quality that are in no way inferior to conventionally produced high-performance tools.
Fraunhofer IKTS counts decades of proven expertise in the development of hardmetals. To date, reliable cutting, drilling, pressing and stamping tools made of...
