Medical Elastomers and the Chemistry Divide: Why BioFlex® and TPU Are Not Interchangeable
BioFlex® is a polypropylene random copolymer (PP-R), not TPU; online sources misidentify it routinely, but the chemistry difference affects sterilisation compatibility, migration risk, and tissue response in fresh piercings.

PTFE and BioFlex PP-R are both used as non-metal body jewellery — but they are fundamentally different polymers with different processing constraints. PTFE cannot be injection-moulded. It must be extruded as rod. Decorative ends threaded onto PTFE rod rotate freely in wear, facing the wrong direction within days. BioFlex is injection-moulded as a single piece: no rotation axis, no misaligned crystals, no orientation problem.
