Jayant Agro: Fuel Line Made of Renewably Sourced DuPont™ Zytel® Nylon Provides Long-Term Resistance to Biodiesel

Castor oil derivatives specifically sebacic acid is used to produce "Fuel lines" used by diesel engines and bio-diesel engines. 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.

Geneva (PRWEB) October 18, 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. As well as seeking to increase the use of renewably sourced polymers to reduce dependence on fossil fuels, automotive component 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 percent 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 percent biofuel from rapeseed and recycled vegetable oil and 70 percent 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 also is market leading in terms of its renewably sourced content. “With more than 60 percent 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 has encouraged Hutchinson to extend the application to other automotive manufacturers in Europe and beyond as well as other fuel system applications. Hutchinson is a subsidiary of the Total Group with representations in Europe, America and Asia, and is one of the world’s leading suppliers to the automotive industry. The product portfolio includes components for vibration technologies, drive train systems, sealants and adhesives, fluid transfer systems (low and high pressure), body parts and sealing systems as well as precision seals and molded parts.

Conclusion: The race is "ON" just like the demand for "GOLD" as an investment was in every investors mind.  Renew-ably sourced, decreasing dependence on fossil fuels, and protecting life and the environment are the buzzwords and castor is the underlying source. The good part is castor derivatives have always been superior to crude oil derivatives so we are going to get better product/performance characteristics and demand is going to increase.. I hope India and Jayant can increase production with competitive pricing to increase their market share of the emerging "Green Chemicals" business.

Very interesting. Thanks for digging up the article. Lets hope India and Jayant rise up to the challenge and be a leader.

I see China as the largest producer of Sebacic Acid. Don't know where they are procuring their castor oil from. If Jayant ramps up its Sebabic plant capacities, it will have plenty of castor available.

Did you know castor oil is classified as a strategic material by US to meet it's defence needs.

Castor oil derivatives are used in stem cell treatment (tissue re-engineering) also for type II diabetes treatment.

Because of unlimited industrial applications and lack of synthetic or any other alternative
.. castor oil enjoys tremendous worldwide demand.

china has sebacic acid production capacity but raw castor oil is imported from india. One of the promoters of Jayant agro holds a patent for sebacic acid production process.
