BioFlex PP-R offers specific mechanical advantages for initial piercings, flexibility reduces leverage pressure on the healing channel. But the fastest-healing piercing is one performed and cared for correctly, not one done with any single prescribed material. Here's what 25 years of watching piercings heal has taught the man who invented BioFlex.

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.

Metal piercing jewellery creates a rigid lever at the piercing site. Under impact, a tackle, a fall, a helmet edge, that lever transmits force directly to the tissue. BioFlex PP-R flexes under impact. For rugby nipple piercings, navel bars in grappling sports, helix piercings under helmets, and chlorinated pool swimming, BioFlex is not just preferable, it is the right engineering answer.
