Let’s reimagine the safety and performance capabilities of EV and hybrid battery packs together.

 

Battery Pack Assembly
Why are silicone foam and thermally conductive silicone ideal for battery assembly?

Mitigating thermal propagation with advanced silicone solutions

Passenger safety within an electric vehicle is of paramount concern. Standards are developing to address such concerns, but some OEMs are targeting solutions that will comply with stricter requirements predicted for the future. These increasing standards are driving the need for improved battery safety and materials for mitigation of thermal events such as fire, explosion or smoke.

Take on the heat with Dow silicone solutions for your battery fire protection challenges.

Dispensing DOWSIL™ EF-6525 RTV Low Viscosity Silicone Foam with a Graco EFR Metering System with Voltex two-component mix valve.

Silicones offer several material advantages for thermal mitigation, including fire-retardant properties and a unique capacity to self-extinguish, avoiding propagation when flames ignite. Additionally, they offer performance over a wide temperature range and can withstand high temperatures from electric vehicle thermal runaway.

Silicone materials are available in different formats, offering a range of thermal insulation and fire protection performance for different cell types and module and pack configurations.

Dow offers a broad product portfolio of silicone materials for battery fire protection, including:

  • LSR coatings and encapsulants offering rapid room-temperature cure, thermal and flame protection.
  • Foams offering rapid room-temperature cure, encapsulation, vibration reduction, thermal and flame protection.
  • HCRs offering rapid cure, electrical insulation, superior thermal and flame protection
