Mevopur™ Healthcare Colorants and Formulations and Mevopur™ Healthcare Functional Additives for In Vitro Diagnostic Devices Diagnostic devices and consumables, now more than ever, play a vital role in delivery of safe treatements. Plastic materials offer opportunities and play an increasingly vital role: colors aid identification and automated laboratory processes while functional additives expand the usable property window of the polymer in areas such as surface chemistry or oxygen protection. FUNCTIONALITY TARGET APPLICATIONS BLOOD COLLECTION REAGENT CONTAINERS/ KITS PIPETTE/ LABWARE SELF-TESTING/ POCT INSTRUMENT/ ACCESSORIES Colorants for coding for lab automation/ identification Wide range of colors in various polymers, available in ready-to-use formulation or concentrate adapted to your process     Colors – low migration/ interference Ready-to-use formulation to avoid interference with analytical tests; extractable metal data    Colors – biologically evaluated Reduced risk of non compliance to current and proposed regulations such as IVDR     Color in PP, ABS, PC and high temperature polymers with UL listings Ready-to-use solutions/concentrates supporting Underwriters Laboratory requirements of electric enclosures   Antistatic for PP, ABS, PC/ABS Permanent/non-migrating ready-to-use formulation; fast decay time independent of % relative humidity   Clarifying PP Sorbitol-free, minimizing potential migration   Laser marking for UDI replacing ink printing/labels Activation of the polymer to laser energy give high contrast solvent-free, high speed identification     Laser welding for fast, reliable assembly of a range of polymers Custom concentrates and ready-to-use formulations for optically transparent and opaque colors while allowing laser transmission/absorption    Nucleation of semicrystalline polymers e.g.

KEY CHARACTERISTICS • Eliminates secondary coating operations • Easily delivers the last drop out of a container • Reduces residual content • Reduces production costs • Won’t impact visual clarity • Non-PFAS formulations available APPLICATIONS Cesa Low Retention Additives are suitable for any olefinic application that would benefit from the ability to repel water or fluids, including: • Labware, including pipette tips • Monofilaments • Industrial fixtures • Woven fibers • Platform mats • Molded optical lenses • Medical devices • Extruded films • Carpet fibers • Textiles PRODUCT BULLETIN

These materials combine the performance of select engineering resins with reinforcing additives, such as carbon powder, carbon fiber, nickel-coated carbon fiber and stainless steel fiber, for low-to-high levels of conductivity depending upon application requirements. PROBLEM CAUSE SOLUTION Incomplete Fill Melt and/or mold temperature too cold Mold design Shot Size • Increase nozzle and barrel temperatures • Increase mold temperature • Increase injection speed • Increase pack and hold pressure • Increase nozzle tip diameter • Check thermocouples and heater bands • 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 • Increase shot size • Increase cushion Brittleness Melt temperature too low Degraded/Overheated material Gate location and/or size • Increase melt temperature • Increase injection speed • Measure melt temperature with pyrometer • Decrease melt temperature • Decrease back pressure • Use smaller barrel/excessive residence time • Relocate gate to nonstress area • Increase gate size to allow higher flow speed and lower molded-in stress Fibers on Surface (Splay) Melt temperature too low Insufficient packing • Increase melt temperature • Increase mold temperature • Increase injection speed • Increase pack and hold pressure, and time • Increase shot size • Increase gate size Sink Marks Part geometry too thick Melt temperature too hot Insufficient material volume • Reduce wall thickness • Reduce rib thickness • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase shot size • Increase injection rate • Increase packing pressure • Increase gate size Flash Injection pressure too high Excess material volume Melt and/or mold temperature too hot • Decrease injection pressure • Increase clamp pressure • Decrease injection speed • Increase transfer position • Decrease pack pressure • Decrease shot size • Decrease injection speed • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease screw speed TROUBLESHOOTING RECOMMENDATIONS PROBLEM CAUSE SOLUTION 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 Burning Melt and/or mold temperature too hot Mold design Moisture • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease injection speed • Clean, widen and increase number of vents • Increase gate size or number of gates • 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 too low Mold design • Increase pack and hold pressure • Increase melt temperature • Increase vent width and locations • Increase injection speed • Increase mold temperature • Decrease injection speed • 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 Mold design • Increase cooling time • Increase melt temperature • Decrease injection pressure and injection speed • Increase number of gates Sticking in Mold Cavities are overpacked Mold design Part is too hot • Decrease injection speed and pressure • Decrease pack and hold pressure • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time • Increase draft angle • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time TROUBLESHOOTING RECOMMENDATIONS www.avient.com Copyright © 2020, Avient Corporation.
