AI Technical Summary
In polymer extrusion processing, the accumulation of material at the die orifice leads to low manufacturing efficiency and product quality problems, and existing technologies are unable to effectively reduce the rate of material accumulation at the die orifice.
By using non-fluorinated polymer processing aids, the rate of die buildup is reduced by blending polyolefins with compositions of polyethylene glycol, polycaprolactone, polypropylene glycol or their copolymers with phosphorus-containing compounds of specific structures.
It significantly reduces the formation of die sprue buildup, improves manufacturing efficiency and product quality, and reduces production losses and additional costs caused by clearing die sprue buildup.

[0001] Cross-reference to related applications
[0002] This patent application claims priority to U.S. Provisional Patent Application Serial No. 63439041, filed January 13, 2023. The subject matter of U.S. Provisional Patent Application Serial No. 63439041, filed January 13, 2023, is incorporated herein by reference. Background Technology
[0003] In polymer extrusion processing, it remains necessary to eliminate or reduce the rate of accumulation of unwanted material on the heated die (die head, mold, die), i.e., to eliminate or reduce the rate of unwanted die buildup (die buildup, mold buildup, mold buildup) on the heated die. Die buildup can adversely affect the quality of the extrudate (i.e., the composition extruded from the heated die) because some of the accumulated die buildup can detach or peel off from the heated die and appear in the extrudate as black specks or other types of contamination. Contamination caused by die buildup often results in extrudates or extruded products, such as extruded polymer films, failing to meet quality standards. This, of course, leads to inefficiencies in manufacturing.
[0004] Due to the die buildup rate in extrusion processes, the manufacturing process must periodically shut down for maintenance for a period at least equal to the time spent clearing the buildup from the heated die. These periods of inactivity result in lost production, which in turn leads to additional manufacturing costs. Summary of the Invention
