Maxxam™ FR FLAME RETARDANT POLYOLEFIN FORMULATIONS PROCESSING GUIDE Injection Molding Parameters Maxxam™ FR flame retardant polyolefin formulations are engineered to meet stringent flammability performance requirements. Only naturally balanced runner systems (“H” pattern) are recommended • Each 90° bend in the system should step down in size • Vents should be placed at the intersection of each 90° bend off of the cold slug well and vented to atmosphere • Hot runner molds are acceptable and should be sized by the manufacturer. Vents should be placed at the intersection of each 90° bend in the runner system off of the cold slug well and vented to atmosphere Black Specks Contamination • Purge barrel with general purpose PP • Verify correct nozzle is being used • Pull screw for cleaning Degraded/overheated material • Decrease melt temperature • Decrease injection speed • Use appropriately sized barrel Brittleness Degraded/overheated material • Decrease melt temperature • Decrease injection speed • Use appropriately sized barrel Gate location and/or size • Relocate gate to nonstress area • Increase gate size to allow higher flow rate and lower molded-in stress Burning Process related Mold design • Clean, widen and increase number of vents • Increase gate size to reduce shear Fibers/Minerals on Surface or Uneven Surface Appearance Melt temperature too low • Increase injection speed Insufficient packing • Increase hold pressure and time Flash Injection pressure too high • Decrease injection pressure • Increase clamp pressure • Increase transfer position Excess material volume • Decrease pack pressure • Decrease shot size Melt and/or mold too hot • Decrease screw speed Loose clamp • Reset mold height • Increase clamp tonnage Troubleshooting Recommendations Incomplete Fill Melt and/or mold too cold • Increase nozzle and barrel temperatures 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 Nozzle Drool Nozzle temperature too hot • Decrease nozzle temperature • Increase screw decompression Shrink Too much shrink • Increase cooling time Too little shrink • Decrease cooling time 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 Troubleshooting Recommendations (continued) Sticking in Mold Overfilled cavity • Decrease injection rate and pressure • Decrease hold pressure • Decrease cooling time Mold design • Increase draft angle • Polish cores in direction of ejection Part is too hot • Increase cooling time Warp Process related • Increase cooling time • Increase pack pressure • Increase pack time Mold design • Inspect for non-uniform mold cooling Part design • Inspect for non-uniform wall thickness Temperature control unit incorrect temperature • Check settings • Inspect thermocouple Weld Lines Melt front temperatures are too low • Increase pack and hold pressure Mold design • Increase gate size • Perform short shots to determine fill pattern and verify proper vent location • Add vents and/or false ejector pin • Move gate location 1.844.4AVIENT www.avient.com Copyright © 2022, Avient Corporation.
