PROCESS AND APPARATUS FOR UNDERWATER PELLETIZATION OF POLYMERS
The underwater melt cutter die assembly has a die plate (60) or die body having one or more die holes (64) through which molten polymer flows and having a polymer exit face (61). The polymer exit face (61) is in contact with a nonmetallic thermal insulator (69) having a first far face (70) opposite...

| description | The underwater melt cutter die assembly has a die plate (60) or die body having one or more die holes (64) through which molten polymer flows and having a polymer exit face (61). The polymer exit face (61) is in contact with a nonmetallic thermal insulator (69) having a first far face (70) opposite the face in contact with said polymer exit face (61), said first far face (70) is in contact with a backup plate (72) having a second far face (73) opposite a face in contact with said nonmetallic thermal insulator (69), and said second far face (73) is in contact with an abrasion resistant material (71). The die holes (64) can have a reverse taper and are straight. The molten polymer is forced through one or more die holes (64) and as said polymer emerges from said die holes (64) it comes into contact with water and is simultaneously cut. |
