Powertrain
Fluoropolymer coated wires and cables are used in automotive powertrain systems, attached to transmissions and motors. In the harsh, under-hood operating environment insulation, high temperature characteristics, and excellent oil resistance are key. Additionally, with the shift to electrification, excellent dielectric properties are also necessary.

Fluoropolymer and Fluoroelastomer are used in various Electric Vehicle applications as seal materials for motors. Daikin’s Fluoro elastomer DAI-EL and Fluoropolymer POLYFLON PTFE M-Series are commonly used in bearing seals.
Coating material for motor windings
Required characteristics
- Dielectric properties
- Heat resistance
- Oil resistance
- High dielectric breakdown voltage
Daikin Solutions
Higher voltage, smaller next generation drive motors for electric vehicles are under development. Motor winding coating materials must have not only excellent dielectric properties such as a low dielectric constant and a low dielectric tangent, but also exhibit heat resistance, oil resistance, and high dielectric breakdown voltage. Fluoropolymer paint and coating materials meet these demanding requirements.
