  • Process for making thermoplastic polymer pellets
    Patent number: 8709315
    Abstract: Provided is a process for making thermoplastic polymer pellets. The process has the following steps: (a) melting a thermoplastic polymer to form a polymer melt; (b) extruding the melt through a die to form a substantially continuous molten polymer extrudate wherein the die has a contact surface bearing a polymer coating having a surface energy of less than 25 mN/m at 20° C.; (c) cooling the extrudate to form a cooled extrudate; and (d) pelletizing the cooled extrudate to form a plurality of polymer pellets. Provided is also a polymer pellet shipping system and a stable thermoplastic polymer pellet.
