  • Method and apparatus for micropelletization
    Patent number: 9321207
    Abstract: In a method and apparatus for micropelletization of a polymeric material, a melt thread of the polymeric material is formed by an extruder. A flowing gas is directed to the melt thread to form Rayleigh disturbances in the melt thread and break up the melt thread into discrete microdroplets. The discrete microdroplets are then solidified to form micropellets.
