The use of carbon nanotubes to improve conductive elastomers

Abstract

There is a growing requirement for the seals in automotive fuel system connections to have electrostatic dissipation properties. Fluorocarbon (FKM) elastomeric O-ring seals are a significant component in the conductive pathway. Providing this conductivity through the incorporation of carbon nanotubes considerably improves properties over the use of carbon blacks. This results in a seal which is softer with improved processing, stable electrical properties and better permeation resistance.
