Gravi-Tech™ REC Recycled Formulations Gravi-Tech™ REC recycled formulations are density modified engineered polymers based on recycled resin and/or recycled filler from post-industrial recycled (PIR) and/or post-consumer recycled (PCR) sources. They offer a more sustainable alternative to density modified grades that are based on prime/virgin polymers. These polymer formulations have been developed to achieve equivalent performance to prime density modified solutions with added sustainability benefits.

NYMAX™ POLYMER FORMULATIONS PRIME & RECYCLED NYLON THERMOPLASTICS PROCESSING GUIDE 2 Nymax Polymer Formulations Nymax™ and Nymax™ REC Formulations Nymax™ thermoplastics include prime and recycled nylon formulations in both unfilled grades and with various levels of glass fiber and mineral reinforcements. 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. Degraded/ overheated material • Decrease melt temperature • Decrease back pressure • Use smaller barrel • Decrease injection speed Gate location and/or size • Relocate gate to nonstress area • Increase gate size to allow higher flow rate and lower molded in stress Fibers/Minerals on Surface or Uneven Surface Appearance Melt temperature too low • Increase injection speed Insufficient packing • Increase hold pressure and time Processing Guide 5 Sink Marks Part geometry too thick • Reduce wall thickness • Reduce rib thickness Melt too hot • Decrease nozzle and barrel temperatures Insufficient material volume • Increase packing pressure • Increase gate size Flash Injection pressure too high • Decrease injection pressure • Increase clamp pressure • Increase transfer position Excess material volume • Adjust transfer position • Decrease pack pressure • Decrease shot size Melt and/or mold too hot • Decrease screw speed Loose clamp • Reset mold height • Increase clamp tonnage Shrink Too much shrink Too little shrink • Decrease cooling time 6 Nymax Polymer Formulations Burning Process related Mold design • Clean, widen and increase number of vents • Increase gate size to reduce shear Wet material • Check moisture.

The problem is that most polymer housings are not able to resist the chemicals involved in this treatment without cracking. After fully understanding all of the requirements, Avient’s technology team began to formulate an easy- to-mold, durable and aesthetically pleasing specialty polymer that provided processing flexibility and wouldn’t require retooling.
