Foils for foodstuffs or heavy duty floor coverings – modern plastic materials need heat during processing. Coatings or adhesives are dried and plastic foils are pre-treated by heat before embossing or lamination. Carbon infrared emitters from Heraeus Noblelight are helping Polyflor from Manchester in the embossing of heavy duty floor coverings and improving quality.

Infrared systems heat large, flat materials rapidly and homogenously, directly before the press or the embossing station. This saves both energy and cost. Heraeus is presenting infrared emitters for plastics treatment on stand 1121 in Hall B1 at the Fakuma exhibition, which takes place in Friedrichshafen from 18th to 22nd October.
Multi-layer plastic foils are used for the hygienic packaging of foodstuffs. To join the layers together, the foils are heated and then joined by means of calenders.
Heavy duty plastic floor products often have a decorative embossing. To achieve a high quality result, after a pre-heating, the surface is then directly heated again shortly before the embossing station. Whether laminating or embossing, the large surface must always be heated homogenously and, hence, it is important that the correct heat source is selected.Carbon infrared emitters improve the quality of floor coverings
In order to solve the problem, intensive tests were carried out in the Heraeus Application Centre, and as a result, a medium wave carbon infrared system was installed. Short wave infrared radiation penetrates deeply into thick plastic materials, while medium wave carbon infrared emitters can heat the surface better. Tests can demonstrate which radiation is best for specific tasks.
Neil Holden of Polyflor is convinced of the benefits of the infrared system, “The new system has ensured that embossing no longer affects floor covering geometry. We were very impressed with the tests carried out at the Heraeus Application Centre and with the way that the system was installed with minimum interruption to the production process.”
Process Improvement by Exact Matching
Infrared heating technology offers various possibilities to optimize industrial processes:• High heat transfer capacity
• Fast response times to reduce energy consumption
Consequently, infrared heat is always used when heat processes are to be implemented which require particular targets in terms of space, time or quality.Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China and Australia, is one of the technology- and market-leaders in the production of specialist light sources. In 2010, Heraeus Noblelight had an annual turnover of 98.9 Million € and employed 689 people worldwide. The organization develops, manufactures and markets infrared and ultraviolet emitters for applications in industrial manufacture, environmental protection, medicine and cosmetics, research, development and analytical measurement techniques

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
