Current Developments in Underwater Re-pelletization of Nylon, PET and High-MFI PP
MetadataShow full item record
This talk describes the latest underwater pelletizing technology in comparison with the more traditional strand pelletizing and water slide systems. Effects of the spherical shape of the underwater cut pellet verses the cylindrical shape of a strand cut pellet will be discussed in detail. Production considerations, such as line startup, process automation and system maintenance will also be outlined for each system. Conclusions will be drawn as to the application of each pelletizing technology for the reclaiming of Nylon, PET, PP and other fibrous waste.
