Energize Electric Vehicles with Viton™ Fluoroelastomers

Chemours Viton™ Fluoroelastomers are poised to assist high-voltage cables that help fuel and power electric vehicles (EVs). Viton™ Fluoroelastomer is an advanced insulation FKM material that offers outstanding thermal, high-voltage, and chemical resistance in many applications. Viton™ Fluoroelastomers harness and energize electric vehicles for more extended durability by supporting high-voltage and high-current drive systems. 

OEMs manufacturing batteries, cables, or chargers require elastomer material that allows for high-quality performance and offers electrical power transmission at a very high voltage. The insulation of this material must be able to handle extreme thermal temperature and high-voltage parts performance. Furthermore, it must be able to protect the specific application by controlling leakage of electrical current.


Due to performance and safety at the forefront of most manufacturers' concerns, the material must also be lightweight. Lightweight materials are essential for electric vehicle parts in the mile range that a battery can hold on a single charge. The automotive industry requires materials that can withstand high temperatures, voltages, and extended periods between inspections. The focus has transferred from traditional automotive materials to combustion engines like gasket seals, hoses, and O-rings. Even with the pivot from standard combustion motor parts, EV components such as connectors and inverters must maintain similar chemical resistance and dielectric capabilities. 

Why Viton™ Fluoroelastomers for EV?

Viton™ Fluoroelastomer has a long-standing history of outstanding performance for electrical cable components within various industries. Viton™ Fluoroelastomers outperform traditional cable systems for electronic vehicle applications because they provide:

  • Superior chemical resistance
  • Outstanding extreme-temperature performance
  • Lightweight and mile-efficient charges
  • Longer durability
  • Heat and fluid resistance
  • Resistance to environmental conditions
  • Dielectric strength
  • Excellent flexibility and resilience
  • Volumetric intrinsic resistance

     Featured Viton™ Grade for EV

Electric automotive manufacturers require a solution to meet the demand for high-voltage and high-current drive systems. Viton™ Fluoroelastomer polymer technology was developed for high-demanding EV applications and to solve the various problems in maintaining safety and performance. The Viton™ Fluoroelastomer Viton™ B-50 meets a wide range of performance expectations for the electric vehicle industry. 

Viton™ B-50 is a B-type gum polymer with a higher viscosity than other B-type gum polymers. Viton™ B-50 can help power electric vehicle components from power chargers to inverters and provide:

  • Superior flexibility under dry heat
  • Improved resistance to fluids
  • Higher viscosity for improved processability 

Potential Viton™ EV Applications

Traditional combustion automotive parts like O-rings, gaskets, seals, and hoses benefit from the chemical-resistant properties of Viton™ Fluoroelastomer. However, electric vehicle environments require consistent dielectric performance to keep EVs safe and long-lasting. EV cables and chargers must handle the high-voltage stress while preventing contact of high-voltage conductors by consumers or controlling leakage of the vehicle's electrical current. Viton™ Fluoroelastomer is an advanced insulation material that keeps high-voltage cables safe while operating at extreme temperatures. 

Performance For Demanding EV Environments

EVs require high-temperature and voltage capability while being able to endure harsh environments. Lithium-Ion batteries produce large amounts of heat; because of this, thermal power cables have had to expand in size and capability to meet these growing service requirements. It is vital to select the right materials that can withstand high temperatures, high voltage, and longer periods between inspections, and protect the passenger from heat generated by the electrified engine and powertrain components. 


Automotive OEMs and electric vehicle component manufacturers require products that stand the test of time and provide superior performance. High-quality fluoroelastomers such as Viton™ Fluoroelastomers can extend the life of various EV components thanks to their outstanding performance over a long period of time, excellent flexibility, and ability to perform well in high-voltage and high-temperature environments.
