Paʻa ahi hua melamine can be installed between the module, battery cell and battery pack shell. Melamine foam may be assessed as one thermal or acoustic layer in a battery pack, but its ability to delay heat propagation or influence thermal-runaway behaviour must be established in the specific installed assembly. Foam alone cannot be relied on to stop cell-to-cell thermal runaway or fire spread. The structure of the battery box can also use high-strength materials, use reinforcing ribs or set up buffer devices, etc., and set up buffer structures to buffer and absorb part of the force of collisions, protect the battery pack from damage, and reduce the risk of short circuits caused by mechanical collisions.
At present, the fireproof materials of new energy vehicle battery packs are mainly laid with fireproof felt materials, such as insulation blankets, mica boards, ultra-fine glass wool, high silica cotton felts, etc. Although fireproof felt can effectively isolate heat diffusion, control the direction of fire, and delay the heat diffusion time of the battery, adding fireproof felt also has problems such as increased mass, which is not conducive to the development of lightweight vehicles, poor heat dissipation performance, and limitations in the design and construction process. Therefore, according to the market demand for safety and lightweight of power battery packs, melamine foam is one candidate for selected nonstructural thermal and acoustic functions in battery assemblies, subject to cell-level and system-level safety qualification.

- Flame behaviour: confirm UL94 and other applicable results using the specific material grade and test report; these do not establish battery-pack fire safety
- maikai wela ʻaila (Ka wela wela, 0.035 W/ (m*K))
- Electrical insulation: a dielectric rating must be demonstrated through applicable dielectric-strength, withstand-voltage, creepage and assembly-level tests; no voltage rating is implied by foam resistivity alone
- Service temperature: evaluate the exact foam grade, exposure duration and complete assembly; published material temperature limits are not an automatic battery-system rating
- Hiki ke hoʻololi (hiki i ka lahilahi ke hiki i ka 0.3mm)
- Māmā(8~51KG/M3)
- Substance, emissions and acoustic performance: verify with grade-specific documentation. Combustion products must not be described as non-toxic; chemical resistance, antimicrobial properties and NRC depend on testing, grade and installed thickness
