What foam is used in EV Batteries?
Two Chemistries. Endless Possibilities.
We offer two types of foam chemistries that are used in electric vehicle batteries - polyurethane foam and silicone foam. These foams provide insulation around battery cells to help regulate temperature and prevent overheating.
We're actively developing new product formulations to meet our customers' specific battery design requests. Learn about comparisons between our silicone and polyurethane materials and reach out to a member of our team to see how we can help integrate low-density foam materials into your EV battery pack.
Polyurethane Expanding Foam
- Light weight and Low viscosity
- Easy to flow in small gaps
- Expands during cure
- Operating temperature of 100 C
- Lower dielectric strength
Silicone Syntactic Foam
- Light weight and Low viscosity
- Easy to flow in small gaps
- No change in volume during cure
- Operating temperature of 200 C
- High dielectric strength (> 20kV/mm)
