Electric cars powered by batteries weigh a lot more than cars powered by combustion engines, so they use a lot of energy.
The greatest obstacle to electrifying transportation is this. OEMs and Tier 1 companies strive to make their upcoming models more effective and efficient.
Faster charging and a wider range are guaranteed by switching to 800V technology. However, higher voltages put even more stress on the primary insulation, resulting in partial discharge and motor failure.
In hairpin or wave windings, contemporary design principles employ rectangular wires with a thicker insulating layer.
It is possible to increase the voltage without compromising the motor’s fill factor by making use of special polymers like PEEK and PI, which are both extremely resistant to partial discharge.
However, when compared to more common polymers, fluoropolymers like PTFE and PFA have superior partial discharge performance and the lowest relative permittivity of the insulating polymers.
Additionally, this benefit becomes even more apparent at electric powertrain operating temperatures. It has been determined that a wire coated with a fluoropolymer operates at three times the voltage of a wire enameled with PAI and nearly two times the voltage of a wire coated with PEEK.
This represents a game-changing advantage for systems of 800V and more. However, fluoropolymers are rather soft materials and have relatively poor resistance to abrasion and minor clamping force.
They show low adhesion and are difficult to extrude. Therefore, traditional technology of wire enameling and wire extrusion was unable to work with fluoropolymers.
The Global EV Fluoropolymer motor seal market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Due to their unique non-adhesive and low friction properties, superior heat, chemical, and weather resistance, and superior electrical properties compared to other polymers, fluoropolymers are utilized extensively in automotive, aerospace, semiconductor, electronics, and common household appliances.
Two extensive lines of fluoropolymers have been developed by DAIKIN: – The POLYFLON Series, a selection of PTFE with high performance.
Available as molding powder, fine powder, or dispersion for use in tubes, membranes, and other applications .
The NEOFLON Series, a comprehensive collection of melt-processable fluoropolymers like FEP, PFA, ETFE, and PCTFE that are appropriate for use in roofing, sealing, and other applications.
