Drying Conditions
A dehumidifying dryer is recommended (relatively hygroscopic).
Melt Temperature
⚠ Thermal degradation risk above 310°C
Minimize residence time and avoid exceeding this temperature.
Mold Temperature
GF-reinforced grade: 80-100°C

Field Notes
PA66: narrow processing window. Moisture is almost always the #1 suspect (40%+ of silver streak). Thermal degradation above 300°C. GF grades warp from fiber orientation. Normal molding up to 305°C is possible; above 300°C minimize residence time.
