Non-Cellular Elastomer: A Safer Alternative to Foam Potting
When it comes to batteries, the stakes are high. A single malfunctioning cell is capable of a thermal runaway event that can result in a fire or explosion. However, when safety is put at the #1 design element, Epic Resins potting solutions come out on top. Potting your battery with a non-cellular elastomer is far superior compared to traditional foam potting solutions. Unlike foam, which compromises your battery pack's structural integrity and thermal performance, our elastomers form a dense, rugged, uniform barrier that contains thermal events and reduces propagation.
Why non-cellular elastomers outperform foam:
-
Superior flame propagation mitigation to prevent the spread of a thermal event
- Vibration and impact resistance due to its excellent adhesive properties
-
Rugged structural integrity is suited for extreme environments
- Excellent moisture resistance to protect against corrosion
-
Consistent, easy processing every time for high-volume production
- Strong thermal conductivity properties allow it to dissipate heat effectively
