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

Weight Reduction Concept: Cable Comparison
AFLAS Performance Over XL-PE Cable
Advantages of AFLAS cable concept:• Non-Flammable
• Weight Reduction
• Improved Flexibility
• Vibration Resistance
• Excellent Heat Resistance
• Superior Chemical resistance
Disadvantages of XL-PE material usage:• Filler added (lots of Mg(OH)2)• Stiff• Limited Heat Resistance
