Material Handling

Aegis® H8202NLB 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.

Technical Details & Test Data

Injection Molding Guidelines

Typical Profile

Melt Temperature: 240-280°C (464-536°F)
Mold Temperature: 80-95°C (176-203°F)
Injection and Packing Pressure: 35-125 bar (500-1500 psi)

Mold Temperatures

A mold temperature of 80-95°C (176-203°F) is recommended, but temperatures as low as 10°C (50°F) can be used where applicable.

Pressures

Injection pressure controls the filling of the part and should not be applied for 90% of ram travel. Packing pressure affects the final part and can be used effectively in controlling sink marks and shrinkage. It should be applied and maintained until the gate area is completely frozen off.

Fill Rate

Fast fill rates are recommended to ensure uniform melt delivery to the cavity and to prevent premature freezing.
