Carbon Nanotubes are being introduced for their enhanced performance. These include thermal and electrical conductivity, structural strength and stiffness, and thermal stability. A recently performed test showed that the Tek-MixTM process can disperse and percolate carbon nanotubes such that a 3½ % carbon nanotube loading can be used in pure HDPE, versus typical levels of 7% (shown by the arrow in the graph). It is difficult to disperse CNT's in HDPE; thus, high loadings are normally required to compensate for incomplete dispersion. As reported in Bayer literature, typical CNT dispersions have a large agglomerate size, such as shown below for Baytubes C 150P. The objective is to turn 750 µm particles, as received, into a network of fine nano fibers of diameter 1 to 2 nm.
