No PFAS/PFOA Statement — Repazole® PBI is Inherently Fluorine-Free

No PFAS / PFOA Statement

As global attention to the environmental and health risks of per- and polyfluoroalkyl substances (PFAS) continues to grow, a growing number of customers now require materials to be "fluorine-free" at the material-selection stage. Guangzhou Riebom New Material provides inherently fluorine-free, high-performance solutions with its Repazole^® PBI product family.

1. Why PBI Is Inherently Fluorine-Free

Repazole^® PBI (polybenzimidazole) is a wholly aromatic heterocyclic polymer whose backbone is built from conjugated benzimidazole and aromatic rings. It contains no C–F bonds whatsoever. This is fundamentally different at the molecular level from fluoropolymers such as PTFE, PVDF, and perfluorosulfonic-acid proton-exchange membranes, where fluorine is a constituent element. PBI's fluorine-free nature is therefore an intrinsic property of the material — not the result of post-treatment removal.

2. The Global Shift Away from PFAS

The EU is advancing a comprehensive PFAS restriction proposal (under the REACH framework), and multiple countries and regions are tightening the boundaries on fluorinated substances. Within advanced-manufacturing supply chains such as semiconductors and electronics, explicit "fluorine-free / low-fluorine" material requirements have already emerged. For critical-component materials, compliance with fluorine-free specifications is shifting from a differentiator to a market-access requirement.

3. Riebom's Fluorine-Free Assurance

Dimension	Commitment
Raw Materials	Repazole^® PBI raw materials contain no PFOA / PFAS substances.
Production	No PFAS / PFOA-containing materials are added at any stage of production.
Verifiable	Rigorous testing ensures products are 100% fluorine-free; fluorine-free test reports and compliance statements are available on request.

4. Typical Fluorine-Free Applications

Semiconductors: dry-etch chamber components, low-outgassing plasma-resistant environments — PBI's high temperature resistance, low outgassing, and inherent fluorine-free nature avoid contamination risks from fluorinated materials.
Hydrogen & New Energy Storage: vanadium-flow-battery proton-exchange membranes (Repazole^® PBI membrane) are fluorine-free, offering a PFAS-free option for energy-storage systems.
Aerospace & Specialty Protection: lightweight high-temperature structural parts, flame-retardant protective equipment.
