8320-V Foam the structural needs of power battery Gentle compression curve Great resistance to compression set

Huitian 8324-V/8320-V series foam is specially designed and developed for the structural needs of power batteries. Its gentle compression curve and excellent compression rebound performance guarantee ample buffering capability for new energy batteries, effectively absorbing and mitigating shocks during the battery charging and discharging process. The low-density foam offers a wide compression range, allowing for a maximum compression ratio of up to 80%. Additionally, its exceptional compression and permanent deformation ensure the foam’s outstanding durability. Huitian 8324-V/8320-V series foam maintains stable compression rebound performance and compression permanent deformation performance even in long-term exposure to hot and high-humidity environments. It can sustain over 90% of its compression performance after millions of compressions, ensuring the durability of batteries in various harsh conditions.Product FeaturesGentle compression curveExcellent resistance to compression setUniform foaming, fast reboundExcellent aging resistanceOutstanding cycling performanceGreat low-temperature resistanceHigh design flexibilityTypical ApplicationBuffer between soft pack battery cellsBuffer for battery pack housingBuffer for battery liquid cooling plateGap filler in battery packsPropertyTest method8324-V8320-VThickness, mm-0.7, 1.0, 1.2, 1.52.0, 2.5, 3.0, 4.0Density, kg/m³ASTM D3574240± 24200 ± 20Hardness, shore 00ASTM D22403832Compression Force Deflection kPa@25%ASTM D35742518Compression Force Deflection kPa@50%ASTM D35744836Compression set %ASTM D3574<3 (at 70%), at 23℃ for 7 days<5 (at 70%), at 70℃ for 72hThermal ConductivityASTM D54700.0650.07Surface resistivity, ΩASTM D2573 × 10^124 × 10^12Volume resistivity, Ω·cmASTM D2575 × 10^145.5 × 10^14Dielectric strength, volts/milASTM 149180150Dielectric constantASTM 1501.91.7Flame resistanceUL94-HBHBFHBF
