Created by Patrick Poli

BioFlex® was developed at Europierce Worldwide Ltd in the United Kingdom in the late 1990s. More than a year of injection trials, mould development, and formulation testing went into the material before it was considered ready. It was certified to ISO 10993-6 and FDA Class IV before any regulator required it — not to meet a standard, but because it was the right thing to do.

BioFlex® is a medical-grade random copolymer in the PP-R class. It is not TPU. It is not thermoplastic urethane. It is not acrylic, PMMA, nylon, or PVC. It shares none of their toxicological profiles and none of their regulatory problems. The confusion in the market — and in some regulatory frameworks — stems from cheap uncertified copies being sold under the same name, not from any failing of the genuine material.

Patrick Poli is the creator of BioFlex® and Director of Poli International Co., Ltd (formerly Europierce Worldwide Ltd, UK). The full story — including the counterfeit problem, the APP's silence, and why the "post-operative use only" label is a category error — is set out in the article below.

BioFlex® in Practice

Seven cases where the material choice is not cosmetic — it is the difference between a healed piercing and a damaged one. Written by the inventor of BioFlex®.

Polymer Science
Initial Piercings and the Right Material
Why the material chosen for a first piercing matters more than most professionals realise — and why BioFlex PP-R reduces the mechanical load on healing tissue from day one.

BioFlex vs PTFE: Why PP-R Wins Every Time
PTFE and BioFlex PP-R are both non-metal options — but they are fundamentally different polymers with different certifications, different processing constraints, and different long-term safety profiles.

Polymer Science
Why Metal Fails Athletes
Metal creates a rigid lever at the piercing site. Under impact, that lever transmits force directly to healing tissue. BioFlex flexes with the body instead of transferring the load.

How to Hide a Piercing at School, Work, or Hospital
BioFlex retainers flex with the body and sit flush against the skin — the only practical solution for dress codes without removing your piercing.

Pregnancy and Piercings: Why Rigid Metal Is Wrong
A navel piercing does not need to be removed during pregnancy. But the jewellery must change. Rigid metal creates mechanical leverage against expanding tissue — BioFlex flexes instead.

The Dental Bill Your Metal Jewelry Is Running Up
Metal oral jewellery — tongue bars, labrets, lip rings — causes measurable enamel erosion and gum recession in long-term wearers. BioFlex eliminates the mechanical cause entirely.

Your Piercing and Your MRI
Every major MRI safety protocol requires metal jewellery removal before scanning. BioFlex PP-R is non-ferromagnetic, non-conductive, and fully radiolucent — it passes the scanner without question.
