3240 Epoxy Insulation Board for Battery Packs – High-Temp
Moisture-Resistant, Custom Colors Available
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.
1. Core Advantages: Why Choose Yellow 3240 Epoxy Insulation Board?
| 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. |

3. Application Scenarios
Our Yellow 3240 Epoxy Insulation Board is a must-have for battery pack safety across industries, where insulation reliability directly impacts product lifespan and safety:
- Electric Vehicles (EVs): Insulation between battery modules, and between modules and the pack casing—resists high heat from battery charging/discharging.
- Energy Storage Systems: Used in home, commercial, and grid-scale lithium battery packs—moisture resistance adapts to outdoor or basement installation environments.
- Industrial Battery Packs: Insulation for lead-acid or lithium battery packs in electric forklifts, AGVs, and backup power systems—withstands mechanical vibration and workshop humidity.
- Consumer Electronics: Smaller-cut boards for portable battery packs (e.g., power banks) and laptop batteries—ensures safe insulation in compact designs.
4. Customization & Processing Services
To fit your specific battery pack design, we offer flexible customization and pre-processing options:
| Service Type | Available Options |
|---|---|
| Size Cutting | Cut to custom dimensions (minimum 50mm*50mm) with ±0.1mm precision |
| Hole Drilling | Pre-drilled mounting holes (M2–M10) or positioning holes—per your CAD drawings |
| Edge Processing | Deburred edges (to avoid damaging battery components) or chamfered edges (for easy assembly) |
| Surface Treatment | Anti-static coating (optional, for electronics-grade battery packs) |
| Packaging | Standard: PE film + cartons; Custom: Vacuum packaging (for long-distance shipping) or wooden crates (for bulk orders) |
5. Quality Assurance & Order Support
- Quality Certifications: Compliant with RoHS, REACH, and UL 94 V-0 flame retardant standards—meets global safety requirements for electronics components.
- Batch Testing: Every production batch undergoes temperature resistance, insulation, and moisture absorption testing—test reports provided free of charge for bulk orders.
- MOQ & Lead Time: Low MOQ of 10 sheets for standard sizes; ships within 2–3 days. Custom-cut orders deliver within 4–5 days.
- After-Sales: Free sample sheets (up to 3 pieces) for performance testing; 1-year warranty for quality issues (e.g., uneven thickness, insulation failure).
