PESU Extrusion Temperature and Forms
Sorun Belirtisi
【Problem Phenomenon】When PESU is extruded into sheets, rods, films, and profiles, the temperature is improperly set, resulting in poor product quality
Neden Analizi
PESU can be extruded into sheets, rods, films, and profiles, with extrusion temperature from 310-340℃ (Russian literature) to 340-380℃ (handbook), and the decomposition onset temperature of 420℃ provides a safety margin
Çözüm
Start the extrusion temperature at 310-340℃ and optimize according to product form; uniformly control die temperature; slowly cool thick-walled profiles to prevent internal stress; after adjustment, continuously sample to verify the effect, confirm stability before resuming mass production
Temel Çıkarım
PESU extrusion starts at 310-340℃, with the 420℃ decomposition temperature leaving a margin; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
