In battery pack assembly, insulation failure due to high temperature or moisture can lead to short circuits and safety risks. Our Yellow 3240 Epoxy Board solves this critical pain point: as a dedicated battery pack insulation board, it combines exceptional high-temperature resistance, strong moisture resistance, and reliable electrical insulation—making it ideal for lithium-ion, LiFePO4, and lead-acid battery packs in EVs, energy storage systems, and industrial equipment. The bright yellow color also enables easy visual inspection during assembly, reducing quality control errors.
| Advantage | Key Benefit for Battery Pack Manufacturers |
|---|---|
| Extreme High-Temp Resistance | Withstands continuous use at 130℃ (short-term up to 180℃), avoiding deformation or insulation breakdown in high-heat battery operating environments. |
| Strong Moisture Resistance | Water absorption rate ≤0.1% (24h immersion test), maintaining insulation performance even in humid or outdoor energy storage scenarios. |
| Reliable Electrical Insulation | Volume resistivity ≥10¹⁵ Ω·cm, dielectric strength ≥18 kV/mm—effectively isolating positive/negative electrodes to prevent short circuits. |
| Mechanical Durability | Tensile strength ≥80 MPa, flexural strength ≥120 MPa; resistant to impact and vibration during battery pack transport and use. |
| Easy Assembly & Inspection | Bright yellow color enables quick visual checks for missing or misaligned boards; easy to cut, drill, and punch to match custom battery pack sizes. |
