Hurtling polyamide on Ferrari and Maserati

mercoledì, 2 aprile 2014

The bio-based high performance EcoPaXX polyamide 410 from DSM has been selected by Dytech-Dynamic Fluid Technologies for the fuel vapour separators it produces for Ferrari and Maserati sports cars. This solution, in halogen-free flame retardant EcoPaXX Q-KGS6, will increase the fire safety of the cars by combining flame retardancy with a high level of chemical resistance, essential for this application.
The fuel vapour separator is an important element of the complete fuel delivery system in road vehicles. It separates vapours from liquid fuel coming out from the fuel tank, and prevents the liquid fuel reaching - and contaminating - the fuel vapour canister. This prevents the evaporating fumes from reaching the atmosphere while also maintaining proper fuel tank pressures.
While fuel lines themselves have a coextruded outer cover in a flame retardant thermoplastic, fuel vapour separators are most often still made from a non-flame-retardant polyamide. Dytech Dynamic Fluid Technologies, based just outside Turin, Italy, now part of Tokai Rubber Industries group, develops and supplies fuel delivery components and systems for many of the world's leading automotive companies. Dytech chose the innovative halogen-free flame retardant EcoPaXX to meet increasing fire safety requirements as well as a wide range of other demanding requirements for the application.
EcoPaXX is highly resistant and impermeable to conventional gasoline fuel (E10) as well as to the more sustainable E85 fuel. In the SHED (Sealed Housing for Evaporative Determination) test, EcoPaXX fuel vapour separators showed a very low permeation level for E10, of 0.002 grams/24 h. EcoPaXX Q-KGS6 has a UL 94 V-0 flammability rating at 0.7 mm. The high thermal stability of EcoPaXX is demonstrated by its Maximum Continuous Use Temperature of 175°C. This engineering plastic also has very good dimensional stability (proven by short term aging at 100°C), and outperforms current materials used in low temperature impact tests carried out at -30°C. EcoPaXX also passed tube extraction and impact tests after thermal and fuel aging, as well as fatigue resistance. EcoPaXX has, in addition to its unique technical performance, an extra advantage in that polyamide 410 is 70% derived from renewable resources and is certified Carbon Neutral from cradle to gate.
