Low-Extractable Multilayer Tube with Vestamid Polyamide 612

Preventing Migration

The new multilayer tubing system (MLT) 4800 by Evonik Resource Efficiency GmbH in Essen, Germany, is a multilayer plastic tube for low-extractable fuel line systems of polyamide 12. With its low-extractable inner layer of Vestamid polyamide 612, the system includes a significant reduction in extractable substances, according to producer information.

With the new tube, the company added a non-conductive system to the existing conductive multi-layer MSR 7440 tube. It is based on the MSR 4300 system, with a Vestamid polyamide 12 outer layer and a barrier layer of ethylene vinyl alcohol (EVOH) to prevent fuel permeation. The PA6 inner layer of the proven system, however, is replaced by a newly developed low-extractable Vestamid polyamide 612. The producer states that mechanical properties such as low-temperature impact strength, chemical resistance and permeation behavior equal those of the MSR 4300 tubes currently in use.

Alcohol-containing fuels, for example ethanol-containing biofuels, can solve components out of the inner walls of the usual fuel lines. Under certain extreme conditions these substances can clog the nozzles in new, sensitive types of fuel systems, especially if they work on small-diameter nozzles to create an atomized spray of gasoline and air for fuel injection in order to reduce fuel consumption.
