Abstract
Disclosed is a process for pelletizing ultra high melt flow crystalline polymers to produce dust-free, uniform ultra high melt flow crystalline pellet products. The process comprises feeding polymer into melting/mixing means, resulting in molten polymer. The molten polymer is transferred to a droplet forming means that produces droplets of the molten polymer. The droplets collect on a continuously moving cooling conveyer and solidify to form dust-free, uniform ultra high melt flow crystalline polymer pellets. Further, the process produces ultra high melt flow crystalline polymer pellets which are uniformly compounded.
