PP-R BioFlex and Bioplast are not TPU — they are semi-rigid medical polyolefins, and recent elastomer research underscores why the chemistry divide ma

BioFlex® is PP-R, not TPU: this guide explains why chemistry, migration behavior, and fit should drive soft body-jewelry choices. It gives piercers a

Fresh elastomer research refines how silicone, TPU, and PP‑R behave in long‑term body contact, with direct implications for flexible jewelry choices.

BioFlex® is polypropylene random copolymer (PP-R), not TPU. Chemistry decides sterilisation compatibility, migration risk, and fresh-piercing safety.
