BZ-6801-22-H is a two-component polyurethane potting material developed specifically for new-energy soft-pack battery modules. It combines low density, UL94 V-0 flammability rating, and excellent flow characteristics to ensure complete filling and sealing of cell assemblies. With a 1:1 mix ratio by weight and Shore A 60±5 hardness, it offers light-weighting benefits and efficient heat dissipation while adhering to strict safety requirements. Fully RoHS/REACH-compliant, this product is suitable for global deployment and eco-conscious manufacturing.
– Mass Reduction: Mixed density 1.09±0.03 g/cm³ lowers module weight, boosting energy density and extending EV/storage runtime.
– V-0 Fire Protection: UL94 V-0 rated, providing critical flame resistance for high-energy battery systems.
– High Fluidity: Viscosity 400–700 mPa·s enables thorough filling of narrow inter-cell gaps, preventing voids and ensuring thermal uniformity.
– Rapid Processing: Cures in 2.5–3.5 h at 25°C (or ≤40 min at 60°C), speeding production without sacrificing adhesion.
– Thermal Reliability: Stable from –40°C to 120°C, performing reliably in extreme cold and high-rate charge/discharge conditions.
