【Applications】
As depicted in the Battery Module Application Schematic, HI Series foam is installed between battery modules using double-sided tape. In a compressed state, it acts as a robust thermal barrier to prevent thermal runaway propagation—shielding adjacent modules from excessive heat during a thermal event. This design ensures battery packs maintain safety and structural integrity under extreme conditions.
