Case study: Producing Low Washout High-Performance Fuel Lines for Hybrid Cars and Beyond with Rilsan^® Polyamide 11 

Introduction 

The rapid electrification of the automotive industry comes with many technical challenges. One of them is, that when Hybrid vehicles run on the Electric “zero emission” mode, fuel remains stagnant within fuel lines for several days or weeks. This increases the extraction of components from the plastic tube. In addition to insoluble matter (oligomers), soluble content can
be extracted to a level that can be detrimental to the engine (fuel injector clogging). Car makers are looking for competitive “low washout” solutions for use in hybrid vehicles, to solve this
issue and help accelerate the growth of environmentally virtuous vehicles.
