The flow of hydrocarbon and other non-polar liquids over materials such as plastics normally induce static electricity.  One can easily imagine that a resultant spark in the fuel system could have a disastrous, explosive effect.
As a result, many global standards and OEM specifications require that lines carrying liquid fuel must be conductive to provide electrostatic discharge (ESD).  Arkema has developed Rilperm® products within each of our general product categories that provide critical ESD even after exposure to severe fuel environments.
