THERMA-TECH™ THERMALLY CONDUCTIVE FORMULATIONS PROCESSING GUIDE 2 Therma-Tech Therma-Tech™ Therma-Tech™ Thermally Conductive Formulations have been engineered to combine the heat transfer and cooling capabilities of metals with the design freedom, weight reduction and cost advantages of thermoplastics. These materials provide the benefits of proprietary conductive additive technologies and the performance of select engineering thermoplastic resins. Maintain a minimum draft angle of 1° per side. 4 Therma-Tech Troubleshooting Recommendations Problem Cause Solution Incomplete Fill Melt and/or mold too cold • Increase nozzle and barrel temperatures • Increase mold temperature • Increase injection rate • Increase pack and hold pressure • Increase nozzle tip diameter • 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 • Increase shot size • Increase cushion • Decrease transfer position Brittleness Low melt temperature • Increase melt temperature • Increase injection rate • Measure melt temperature with pyrometer Degraded/ overheated material • Decrease melt temperature • Decrease back pressure • Use smaller barrel/excessive residence time • Decrease screw rpm Gate location and/or size • Relocate gate to nonstress area • Increase gate size to allow higher flow rate and lower molded in stress Fibers on Surface (Splay) Melt temperature too low • Increase melt temperature • Increase mold temperature • Increase injection speed • Increase screw rpm Insufficient packing • Increase pack and hold pressure, and time • Increase shot size • Increase gate size Processing Guide 5 Problem Cause Solution Sink Marks Part geometry too thick • Reduce wall thickness • Reduce rib thickness • Maintain nominal wall thickness Melt too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature Insufficient material volume • Increase shot size • Increase injection rate • Increase pack pressure/time • Increase gate size Flash Injection pressure too high • Decrease injection pressure • Increase clamp pressure • Decrease injection rate • Increase transfer position Excess material volume • Decrease pack pressure • Decrease shot size • Decrease injection rate Melt and/or mold too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease screw speed Excessive Shrink Too much orientation • Increase packing time and pressure • Increase hold pressure • Decrease melt temperature • Decrease mold temperature • Decrease injection speed • Decrease screw rpm • Increase venting • Increase cooling time Not Enough Shrink Too little orientation • Decrease packing pressure and time • Decrease hold pressure • Increase melt temperature • Increase mold temperature • Increase injection speed • Increase screw rpm • Decrease cooling time Troubleshooting Recommendations 6 Therma-Tech Troubleshooting Recommendations Problem Cause Solution Burning Melt and/or mold too cold • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease injection rate Mold design • Clean, widen and increase number of vents • Increase gate size or number of gates Moisture • Verify material is dried at proper conditions Nozzle Drool Nozzle temperature too hot • Decrease nozzle temperature • Decrease back pressure • Increase screw decompression • Verify material has been dried at proper conditions Weld Lines Melt front temperatures are too low • Increase pack and hold pressure • Increase melt temperature • Increase vent width and locations • Increase injection rate • Increase mold temperature Mold design • Decrease injection rate • 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 Warp Excessive orientation • Increase cooling time • Increase melt temperature • Decrease injection pressure and injection rate Mold design • Increase number of gates Sticking in Mold Cavities are overpacked • Decrease injection rate and pressure • Decrease pack and hold pressure • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time Mold design • Increase draft angle Part is too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time 1.844.4AVIENT www.avient.com Copyright © 2020, Avient Corporation.

reSound™ REC Recycled Content Thermoplastic Elastomers This material, also known as a thermoplastic elastomer, has a soft, grippy feel and is highly colorable.

While rigid polymers are typically used for this because of their conductive and wireless properties, Avient has found additional value in low signal loss technology within its thermoplastic elastomer (TPE) portfolio. a) what effect do thermoplastic elastomer (TPE) formulations have on the attenuation (energy absorption) of a signal ranging from 20-45 GHz?
