Aegis® H85NP Features & Benefits
Applications & Uses
Material Handling
Aegis® H85NP homopolymer is supplied in sealed containers and drying prior to processing is not required. However, high moisture is the primary cause of processing problems. If drying becomes necessary, a dehumidifying or desiccant dryer operating at 80°C (176°F) is recommended. Drying time is dependent on moisture level.
From flexible packaging for food and consumer products to vacuum bagging for industrial goods, Aegis® packaging grade resins are widely used in a variety of applications, including:
- Processed meats and cheeses
- Coffee, nuts and spices
- Snacks and frozen foods
- Pet foods
- Detergent bags
- Composite fabrications
- Medical devices
- Novelty balloons

Technical Details & Test Data
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):
- The molecular weight (Mw) of the resin: Higher Mw resins will have a higher melt viscosity than lower Mw resins.
- Temperature of the melt for any given Mw resin: Higher process temperatures will provide a more fluid melt viscosity than lower process temperatures.
