Material Handling
Aegis® PCR-H120MP is supplied in sealed containers and drying prior to processing is not required. However, higher moisture is the primary cause of processing issues. If drying becomes necessary, a dehumidifying or desiccant dryer operating at 80°C (176°F) is recommended. Drying time is dependent on moisture level.

Melt Viscosity vs. Temperature
Melt Temperature: 220°C (428°F)
Melt Temperature Range: 232°C (450°F) to 271°C (520°F).
Two key factors affect the melt viscosity (stiffness or fluidity of the melt):
1. The molecular weight (MW) of the resin: Higher MW resins will have a higher melt viscosity than lower MW resins.
2. Temperature of the melt for any given MW resin: Higher process temperatures will provide a more fluid melt viscosity than lower process temperatures.
