Dealing with Biofuels Correctly

Evonik

Alcohol-containing fuels, for example biofuels containing ethanol, can dissolve components out of the interior wall of conventional fuel lines. Under specific extreme conditions, with new, sensitive fuel systems, these block the nozzles. Evonik Industries AG, Essen, Germany, has responded to the latest demands of the automotive industry for low-extractable fuel line systems for use with alcohol-containing fuels by developing the MLT 4800 multilayer tube. It is provided with a Vestamid polyamide 12 outer layer, an ethylene-vinyl alcohol (EVOH) barrier layer against fuel permeation, and a low-extractable polyamide 6.12 interior layer, and shows a reduced content of leachable substances. According to the manufacturer, the mechanical properties such as cold impact strength, chemical resistance and permeation behavior are at the same level as for the systems currently in widespread use in Europe. Furthermore, with Plexiglas NTA-5, a new polymethyl methacrylate (PMMA) type, an enhanced product for the automotive industry can be presented, which, by virtue of its specific properties, is particularly suitable for robust, non-transparent bodies in the lower area of vehicles.

For the textile industry, new biopolyamide fibers based on Vestamid Terra have been developed. The fiber materials are claimed to be lightweight, stretchable, breathable and to inhibit odors thanks to their permanent natural bacteriostatic properties.
