NF150-788 is a liquid silicone foam elastomer developed for thermal insulation, cushioning, and electrical insulation between battery cells in new energy vehicle (NEV) power batteries.

Featuring a fine and uniform closed-cell structure, the material combines excellent compression recovery with low thermal conductivity, high volume resistivity, and UL94 V-0 flame retardancy. It helps accommodate the expansion and contraction of battery cells during charge-discharge cycles while providing effective cushioning, electrical insulation, and thermal protection.

NF150-788 also offers excellent resistance to compression set and low stress relaxation, enabling stable performance over a recommended operating temperature range of -55°C to 200°C.

The material is self-adhesive on both sides and protected with PET release liners, allowing direct peel-and-stick installation without additional adhesive lamination. It is supplied in roll format with a standard width of 1 m and length of 30 m, making it suitable for efficient slitting, die-cutting, and continuous converting processes.

Excellent Flame Retardancy
UL94 V-0 flame rating provides reliable flame-retardant protection for battery and electronic applications.

Low Thermal Conductivity
Thermal conductivity ≤0.12 W/(m·K), helping reduce heat transfer between adjacent battery cells.

Wide Operating Temperature Range
Recommended for continuous use from -55°C to 200°C, with intermittent exposure up to 280°C for 30 minutes.

Excellent Electrical Insulation
Volume resistivity >1×10¹⁴ Ω·cm and dielectric strength ≥3 kV/mm provide effective electrical isolation.

Low Compression Set
Compression set ≤5% after aging at 150°C for 168 hours, helping maintain material thickness during long-term service.

Low Stress Relaxation
Stress relaxation <15% after aging at 150°C for 168 hours, supporting stable compression force under long-term operating conditions.

Excellent Fatigue Resistance
Thickness change remains below 2% after one million dynamic compression cycles, with no cracking or damage.

Low Water Absorption
Water absorption ≤3%, supporting use in high-humidity environments.

Double-Sided Self-Adhesive Design
Integrated low-tack adhesive surfaces with PET release liners simplify positioning and assembly without secondary adhesive lamination.

RoHS & REACH Compliant
Meets RoHS and REACH environmental compliance requirements.

Roll Format for Efficient Converting
Standard 1 m × 30 m roll format supports efficient slitting and die-cutting with high material utilization.

NEV Power Battery Cells
