In addition, the Nymax™ REC series offers PA6 and PA66 grades with post-industrial recycled (PIR) or post-consumer recycled (PCR) nylon to support a circular economy. Additional draft may be required for grained/textured surfaces. 4 Nymax Polymer Formulations Incomplete Fill Melt and/or mold too cold • Increase nozzle and barrel temperatures • Check thermocouples and heater bands Mold design • Enlarge or widen vents and increase number of vents • Check that vents are unplugged • Check that gates are unplugged • Enlarge gates and/or runners • Perform short shots to determine fill pattern and verify proper vent location • Increase wall thickness to move gas trap to parting line Shot size • Adjust transfer position to 98% full • Increase cushion Brittleness Wet material • Check moisture.

Active and passive oxygen barriers are additives that are broadly used in the PET bottle industry, across the value chain; they guarantee the optimal shelf life of packaged goods such as beer, juices, RTD beverages, or condiments, to name a few. The regrind combination study also showed how retention of original standard amber tone could be closely maintained with very minimal addition of Fortis-Amber 1, even after a dilution with 50% vPET of material coming from original packaging articles, with or without the further addition of SolO2-2.

These fiber-reinforced panels offer ballistic resistant security with additional performance advantages, including durability, corrosion resistance, electrical non-conductivity, low thermal conductivity, and reduced weight. Additional protection against higher power ammunitions can be achieved by layering multiple panels; contact Avient for more information regarding your specific application. Reinforce all panel seams with a minimum 4 inch (10.16 cm ) batten of additional ballistic panel material.
