AGC Completes Third-Party Verification Under UL 2809 for Fluorine Raw Materials Used in AFLAS™ FFKM

-Fluorine Content attributed as 100% “Recycled Circular Fluorite” Based on Mass Balance Credit Allocation-

AGC (TOKYO:5201) (AGC Inc., Headquarters: Tokyo; President: Yoshinori Hirai) a world-leading manufacturer of glass, chemicals and other high-tech materials, announces that it has completed a third-party verification*1 based on UL 2809*2 in May 2026 for the fluorine raw materials used in AFLAS™ FFKM. The third-party verification confirmed that, for allocation of recycled content under the mass balance approach*3, 100%*4 of the fluorine content allocated to AFLAS™ FFKM is attributed to recycled fluorite (hereinafter “Recycled Circular Fluorite”). This initiative is among the industry-leading levels*5 of recycled material utilization in fluoroelastomer materials.
