Manufacturing steps for vulcanized rubber— pre-mixing the formulation, subsequent mixing on a two-roll mill, parts molding and secondary operations, including washing off unreacted surplus materials—present manufacturers with a costly, protracted and outdated process. Because they remove the need to wash products and simplify bonding to rigid substrates, TPEs require only one to two minutes of processing time from start to finish, and are ideal when producing dynamic and static seals, liquid storage and delivery packaging, and infusion therapy devices. They may enable you to bolster your sustainability profile by removing potentially harmful chemicals from your process.

Follow up by purging machine with general purpose PP • Residence time should not exceed 5 minutes for Maxxam FR products • General ventilation is suggested Shut Down • Purge the equipment with a general purpose PP • All tooling and equipment must be free of any residual Maxxam FR upon shut down • Continue generating parts made from the natural PP until clear • Wipe down tool steel with mold cleaner • When using a hot runner system, care must be taken to remove residual product from the manifold MOLD DESIGN RECOMMENDATIONS Cold Slug Wells • Place cold slug wells at the base of the sprue to capture the cold material first emerging from the nozzle • Place cold slug wells at every 90° bend in the runner system • Well depths approximately 2–3 times the diameter of the runner provide best results Draft Angle • Draft angle should be 1/2°–1° per side. Half-round or standard trapezoid runners are not recommended. • 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. Increase the vent depth to 0.010" at 0.100" away from the cavity and vent to atmosphere. • 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 PROBLEM CAUSE SOLUTION 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 back pressure • Decrease injection speed • Use appropriately sized barrel Brittleness Degraded/overheated material • Decrease melt temperature • Decrease back pressure • 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 • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease injection rate 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 melt temperature • Increase mold temperature • Increase injection speed Insufficient packing • Increase hold pressure and time • Increase shot size Flash Injection pressure too high • Decrease injection pressure • Increase clamp pressure • Decrease injection rate • Increase transfer position Excess material volume • Adjust transfer position • 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 Loose clamp • Reset mold height • Increase clamp tonnage Troubleshooting Recommendations PROBLEM CAUSE SOLUTION Incomplete Fill Melt and/or mold too cold • Increase nozzle and barrel temperatures • Increase mold temperature • Increase injection rate 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 shot size Nozzle Drool Nozzle temperature too hot • Decrease nozzle temperature • Decrease back pressure • Increase screw decompression Shrink Too much shrink • Increase cooling time • Decrease mold temperature Too little shrink • Decrease cooling time • Increase mold temperature Sink Marks Part geometry too thick • Reduce wall thickness • Reduce rib thickness Melt too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature Insufficient material volume • Adjust transfer position • Increase shot size • Increase injection rate • Increase packing pressure Troubleshooting Recommendations (continued) PROBLEM CAUSE SOLUTION Sticking in Mold Overfilled cavity • Decrease injection rate and pressure • Decrease hold pressure • Adjust transfer position • Decrease nozzle and barrel temperatures • Decrease mold temperature • Decrease cooling time Mold design • Increase draft angle • Polish cores in direction of ejection Part is too hot • Decrease nozzle and barrel temperatures • Decrease mold temperature • Increase cooling time Warp Process related • Increase cooling time • Increase melt temperature • Increase pack pressure • Increase pack time • Decrease mold temperature 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 • Increase melt temperature • Increase injection rate • Increase mold temperature 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.

Versaflex™ TF Adhesive TPE for Textile Fabrics: a cost-effective alternative to TPU adhesive films and traditional glues, free of plasticizers, with low VOC content, OEKO-TEX 100-2 compliance, and excellent washability up to 60°C, combining strong and seamless adhesion to polyester and nylon fabrics with outstanding elastic recovery for high wearing comfort in target applications such as functional sports attire, fitness apparel, and underwear

Shut-Off Design Shut-offs should be designed to: An accent groove of 0.015" to 0.030" (0.381 mm to 0.762 mm) depth and 0.030" to 0.040" (0.762 mm to 1.02 mm) width helps to develop a good shut-off.

IMAGINE THE POSSIBILITIES OFF ROAD Your customers expect performance and durability from your off-road vehicles. You’ll get design support, manufacturing and technical guidance, and polymer recommendations that enhance your profitability and thrill your customers as they travel off road. Our advanced materials, technical expertise and design support can help you create a powerful, ergonomic machine that opens up new paths to off- road nirvana.

High Strength Synthetic Fibers Outperform Steel Our Products Remove • Weight Steel is heavier than synthetic fibers. HMPE for example, has a specific gravity less than 1 and will float in water. • Corrosion Since our products are non-corrosive, they offer outstanding performance in corrosive environments, including marine and off- shore applications. • Conductivity High-performance synthetic fibers act as a barrier between eletrical components. • Creep When exposed to static long-term loads, synthetic fibers stretch very little.
