Preventing Thermal Runaway: Ultimate Cell Isolation with 4.0 W/m·K Flame-Retardant Potting
Safety is the absolute priority in industrial and utility-scale energy storage. When thousands of lithium-ion cells are tightly packed inside a single 20ft or 40ft BESS container, a single failing cell experiencing thermal runaway can trigger a devastating domino effect across the entire battery bank.
Mitigating this risk requires a material that simultaneously delivers ultra-high thermal dissipation and robust fire-retardant barriers. Hanast HN-8840 represents the pinnacle of addition-cure silicone technology, boasting a certified thermal conductivity of 4.0 W/m·K.

When poured between closely spaced cells, HN-8840 eliminates critical air gaps, ensuring uniform heat dissipation during peak shaving or high-load industrial demand cycles. Crucially, the compound is certified to the UL94 V-0 flammability standard, meaning it is self-extinguishing and will not support combustion. In the rare event of an individual cell failure, HN-8840 acts as a highly effective physical and thermal shield, absorbing excessive heat energy and preventing flame propagation to neighboring cells.
