MOSCOW (MRC) -- A new rubber raw material Levapren produced by Lanxess, a leading specialty chemicals company, has helped to develop ininnovative and durable floor covering used in long-range airliners - an alternative to the silicone coverings, according to the company's press release.
Floor coverings used in long-range airliners must meet a wide range of strict requirements, including for safety reasons. This naturally applies in particular to products that need to be fitted in aircraft galleys.
With their new Duroflex and Durofloor floor coverings, engineers from the highly renowned rubber experts Metzeler Technical Rubber Systems GmbH, based in Edingen-Neckarhausen in Germany and a subsidiary of the North American automotive supplier Cooper Standard, Novi, United States, have developed innovative and durable alternatives to the silicone coverings often used up to now.
The new, easily bondable non-slip products are characterized, for example, by outstanding abrasion resistance and fire protection properties and are based, among other materials, on the halogen-free highly fillable rubber raw material Levapren from synthetic rubber pioneer LANXESS.
To date, the most important demands were frequently met by flexible coverings or rigid laminates with a top layer of silicone rubber. These often have the disadvantage of a low Shore hardness, however, which can find expression in comparatively rapid wear and can make the floor sensitive to the falling of sharp objects. And for many cost-conscious clients they were not always first choice for financial reasons.
"In 2002, therefore, we started looking for alternative materials and have put a lot of developmental effort into the project," says Joachim Bormuth, responsible for quality management at Metzeler among other duties. The material that finally convinced his company was a special grade of LANXESS' EVM synthetic rubber Levapren.
A good choice, according to Michael Herrmann, product expert from the LANXESS business unit High Performance Elastomers: "In many ways Levapren is an ideal material: the rubber does not contain any halogens and therefore does not liberate any corrosive acidic gases in the event of fire; rescue equipment then remains intact for longer and human life and materials are spared. On combustion, Levapren has a low smoke gas density, leaving escape routes free for longer should it come to the worst. To let it never get that far, Levapren can be supplemented with large quantities of flame-retardant inorganic fillers, but still remains easy to process."
Levapren has passed its first baptism by fire in Metzeler's Duroflex and Durofloor floor coverings: these have been in service in two aircrafts belonging to a top airline for around one and a half years.
LANXESS is a leading specialty chemicals company with sales of EUR8.8 billion in 2011. The company is currently represented at 48 production sites worldwide. The core business of LANXESS is the development, manufacturing and marketing of plastics, rubber, intermediates and specialty chemicals. We remind that, as MRC reported previously, in September, 2012, Lanxess acquired German company Bond- Laminates GmbH to strengthen its portfolio of lightweight materials for the automotive industry.
