Ultraform N2320 C from BASF is a polyoxymethylene (POM; polyacetal) plastic that contains carbon nanotubes. This material acquires a high level of electric conductivity without sacrificing toughness. Ultraform N2320 C has been used in its first serial application at Bosch for a fuel-filter housing for the Audi A4 and A5. With a value of 30 ohm.cm, Ultraform N2320 C is 30,000 times more conductive than necessary thereby it eliminates the risk of electrostatic charging and sparking as fuel flows through the filter. Due to the type of additives and the way they have been incorporated, the material retains POM-typical properties such as toughness, dimensional stability, and elastic resilience. When it comes into contact with fuels, it is stronger and more creep resistant than conventional POM. It is also less costly than other conductive plastics. Ultraform N2320 C meets measuring conditions according to ISO 3915 as well as the requirements of SAE J1645.
