AFLAS® Fluoroelastomers for HEV/EV Cable Applications

What is AFLAS?

•  AFLAS 100 and 150 Series are unique fluoroelastomers •  Classified by ASTM D1418 as FEPM

•  Totally different from other FKM type fluoroelastomers •  Viton •  Daiel •  Tecnoflon •  Etc.

•  AFLAS 100 and 150 Series are formulated as Tetrafluoroethylene/Propylene copolymer (TFE/P)

•  AGC is the only manufacturer of this polymer in the world

What are the Benefits of AFLAS?

•  Excellent heat resistance •  200°C continuous service temperature

•  Superior base resistance

•  Unmatched electrical resistivity compared to FKM grades •  Used today for various cable insulator applications

•  HEV/EV power cable •  Transmission cable

•  ATF resistant
