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. Available in both halogen and non-halogen products, including grades with UL Yellow Card rating, Maxxam FR products can be customized for specific performance needs. 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.
