Aegis® PIR-H35ZI resin from AdvanSix contains 100% post-industrial recycled (PIR) raw materials while providing the same top performance and processability as Aegis® H35ZI, its standard, non-recycled counterpart.

Aegis® PIR-H35ZI resin is an unfilled, low viscosity, non-lubricated nylon 6 injection molding homopolymer exhibiting excellent melt flow properties for filling thin sections and reduced cycle times. Aegis® PIR-H35ZI homopolymer exhibits good strength, stiffness and toughness as well as excellent heat, chemical and abrasion resistance.

Storage & Handling

Processing Guidelines

Material Handling

Aegis® PIR-H35ZI 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. More information about safe handling procedures can be obtained by requesting the Safety Data Sheet.

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.


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.

Note: The values in this data sheet are for natural color resins only. Colorants or other additives may alter some or all of these properties. The data listed here fall within the normal range of product properties, but should not be used to establish specification limits nor used alone as the basis of design.
