Fuel Permeation Performance of Polymeric Materials 2001-01-1999

This paper presents an extensive set of permeation data on automotive fuel system materials. It adds significantly to the information provided by the same authors in SAE paper 983160 [1]. The permeation measurements refer to three different test fuels: fuel C, CE10 and CM15 at 40, 50 and 60°C. The materials examined include poly-ethylenes, nylons, polyketons, ethylene-vinyl alcohol copolymers, acetals, fluoropolymers and fluoroelastomers. These data are important in the design of automotive fuel system components capable of meeting LEVII or PZEV requirements. In particular, data of this kind are crucial in optimizing the permeation performance of multilayer structures for fuel system applications.
