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) • S5ff • Limited heat resistance
