Melt Viscosity vs. Temperature
Melting point: 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.

Storage & Handling
- Material Handling
Aegis® PCR-H135QP is supplied in sealed containers and drying prior to processing is not required. However, high 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.
