Document Type and Number:
WIPO Patent Application WO/2019/065403
Kind Code:
A1
Abstract:
Provided are an extruder die, an extruder, and a resin composition manufacturing method. The extruder die comprises a discharge surface having one or a plurality of discharge holes from which a melted resin is discharged in the form of a strand; and one or a plurality of protrusions that protrude in the perpendicular direction from the discharge surface. Part of a base portion of each protrusion is in contact with an outer periphery portion of the corresponding discharge hole. The extruder has the extruder die fitted thereto. The resin composition manufacturing method enables a resin composition to be obtained by charging at least a resin and an additive into the extruder and causing the resin composition to be discharged from the extruder die.
