Dispersion – High Viscosity Material
Twin screw extruder
There are basically three ways of incorporating Baytubes® into high viscosity melts:
- melt impregnation
- solvent impregnation.
- in-situ polymerization
For practical reasons we recommend melt impregnation.
The need to disintegrate the agglomerates in order to achieve even distribution of the carbon nanotubes require high shear forces.
Baytubes® in PCExcellent dispersion results are achieved by processing the thermoplastic materials in a twin screw extruder. Twin screw extruder can be used for the production of compounds as well as masterbatches. Masterbatches containing a high concentration of Baytubes® in a polymer matrix can be diluted in either single screw or twin screw extruders. For rubber materials we recommend the use of standard Banbury equipment.
