AGC verifies AFLAS FFKM fluorine as 100% recycled under UL 2809
- May 2026: AGC completed third‑party UL 2809 verification confirming 100% of fluorine allocated to AFLAS FFKM derives from recycled fluorite under the mass‑balance approach.
- Fluorine atoms represent ~73 wt% of AFLAS FFKM polymer; AGC manages raw‑material credits so the entire fluorine component is from recycled material.
- AFLAS FFKM is a high chemical-, heat- and plasma-resistant fluoroelastomer used for semiconductor seals and O‑rings; AGC completed UL 2809 verification for Fluon PTFE in 2025.
Verification
In May 2026 AGC completed a third‑party UL 2809 Environmental Claim Validation confirming, under the mass‑balance approach, that 100% of the fluorine content allocated to AFLAS FFKM is derived from recycled fluorite; the verification covered the management of raw‑material credits and compliance with UL 2809 procedures.
Material composition
Fluorine atoms account for approximately 73 wt% of AFLAS FFKM polymer grades; AGC manages inputs so the entire fluorine component is attributed to recycled material, with the remainder of the polymer composed primarily of carbon.
Applications
AFLAS FFKM is a fluoroelastomer used for seals and O‑rings in demanding environments, offering high chemical, heat and plasma resistance, notably for semiconductor manufacturing.
Circularity actions
AGC recycles fluorine‑containing waste from its plants into “Recycled Circular Fluorite” for use in fluorine products and positions this verification alongside its 2025 UL 2809 verification for Fluon PTFE as part of efforts under the mid‑term plan “AGC plus‑2026” to advance a circular economy for fluorine resources.
