Carbon nanotubes eliminate manufacturing woe

Abstract:
Researchers at the National Institute of Standards and Technology (NIST) have discovered that the addition of carbon nanotubes to a common commercial polymer, polypropylene, leads to dramatic changes in how the molten polymer flows. This process eliminates a widespread manufacturing headache known as "die-swell" in which polymers swell in undesirable directions when passing through the exit port of an extruder.
