Evonik Multilayer Tubing 7440 series
Categories: Other Engineering Material

Material Notes: Conductive, low extractable multilayer tubing system. The multilayer tubing system (MLT) 7400 is an automotive industry proven 5-layer tube for fuel handling systems. With an outer layer of VESTAMID® polyamide 12 and two barrier layers: ethylene vinyl alcohol (EVOH) as middle layer and a fluoropolymer EFEP NEOFLON™ as inner layer. This unique system has very good resistance properties against alcohol-containing fuels, a superior chemical resistance of the inner tube surface and low extractable properties. Regional specifics may require antistatic properties. These are fulfilled by the multilayer tubing system (MLT) 7440 that is based on the aforementioned design but with a conductive fluoropolymer EFEP NEOFLON™ inner layer.
