PHTHALATES FACTS PHTHALATES ARE KNOWN TO BREAK DOWN IN THE HUMAN BODY Research has shown that after entering the body, phthalate are broken down into metabolites within minutes and pass out quickly in urine.2 PHTHALATE EXPOSURE IS CONSIDERED LOW Despite the fact that phthalates are used in a wide range of products, human exposure from all sources is considered to be extremely low.2 PHTHALATES ARE A USEFUL CHOICE FOR HEALTHCARE Flexible vinyl tubing does not react with most medications, allowing for reliable administration of drugs, while flexible vinyl bags prevent blood contamination and extend shelf life of the blood.3 PHTHALATES ARE REGULATED Based on earlier studies, a few specific phthalates have been banned for use in toys or other items for sale to children under twelve to reduce risk of overexposure through hand-to- mouth behaviors. 1 Source: chemicalsafetyfacts.org 2 Source: Centers for Disease Control and Prevention 3 Source: thisisplastics.com www.avient.com Copyright © 2020, Avient Corporation.

Standard grades in the portfolio conform to UL 94 V-2, V-0 and 5VA performance ratings, and many offer elevated Relative Thermal Index (RTI) ratings. Drying non-halogenated materials is suggested. 2 hours @ 100 (38) Moisture Range (%) Not required 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.
