Fuel line made of renewably-sourced DuPont™ Zytel® nylon provides long-term resistance to biodiesel

19.10.2011
The fluid transfer system supplier Hutchinson SRL, of Rivoli, Italy, has specified a DuPont™ Zytel® RS grade based on PA1010 for the production of fuel lines used with both diesel and biodiesel.

The renewably-sourced long-chain nylon was chosen in preference to competitive grades of PA12 on the basis of its superior temperature resistance and long-term aging performance in biodiesel. The extruded, monolayer fuel line from Hutchinson is already in use on commercial new turbo and multijet diesel engines used on several Fiat vehicles, including the Fiat 500, Panda, Punto, Lancia Delta, Alfa Romeo MiTo and Giulietta.

Fuel lines used with both diesel and biodiesel are produced using renewably-sourced DuPont™ Zytel® RS PA1010 by the fluid transfer system supplier Hutchinson SRL of Rivoli, Italy, and debut on all new turbo and multijet diesel engines used on several Fiat vehicles, including the Fiat 500, Panda, Punto, Lancia Delta, Alfa Romeo MiTo and Giulietta.

As well as seeking to increase the use of renewably-sourced polymers to reduced dependence on fossil fuels, automotive manufacturers, OEMs and materials suppliers are modifying engine and fuel systems to run efficiently on the latest generation of biofuels, including biodiesel.

Components for such systems must resist the chemically-aggressive biofuels, temperature extremes and mechanical stresses for the lifetime of the vehicle. This specific Zytel® RS grade based on PA1010, which contains more than 60% renewably sourced ingredient by weight, offers properties typical of flexible polyamides with additional benefits such as superior high temperature resistance when compared to materials such as PA 12, high chemical resistance and low permeability to fuel and gases.

It is suitable for a range of extrusion applications including fuel lines, hydraulic hoses, corrugated tubes, transmission oil cooler hoses and pneumatic tubes. “We were seeking a polymer for our fuel line application that was preferably renewably-sourced, for a more sustainable solution, and was able to provide the best aging stability in biodiesel,” explains Katia Rossi, development manager at Hutchinson. “We considered a number of flexible polyamides, including PA12 as they had previously been specified for similar fuel line systems, but material testing showed Zytel® RS PA1010 to meet our requirements. It combines, for example, superior temperature resistance to PA12 with the best resistance to biodiesel at high temperatures.” Data on aging performance in biodiesel was obtained by immersing the materials in the most common biodiesel – rapeseed methyl ester (RME) – at 125 °C (257 °F) for 1,000 hours and measuring retained mechanical properties. The B30 biodiesel used for testing is made up of 30 per cent biofuel from rapeseed and recycled vegetable oil and 70 per cent standard diesel and is suitable for many diesel cars. By specifying the DuPont material for its fuel line for diesel engines, Hutchinson gains a longer-lasting solution that is also market leading in terms of its renewably-sourced content.

“With more than 60% by weight, this Zytel® RS grade based on PA1010 has one of the highest levels of renewably-sourced content currently available for a high performance nylon,” confirms Mario Delbosco, development programs manager at DuPont Performance Polymers. The renewable carbon in PA1010 comes from sebacic acid, which in turn is derived from castor oil. The successful adoption of renewably-sourced Zytel® nylon for the fuel line, which is already in commercial use on diesel-engined cars, has encouraged Hutchinson to extend the application to other automotive manufacturers in Europe and beyond as well as other fuel system applications.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
