PP Separator (SEP-PP-25), Dry-Process Single-Layer Polypropylene Separator, Zero TD Shrinkage, Li-Ion Battery Separator

About this item

• Zero TD Shrinkage Safety: features zero TD shrinkage (0% @ 90°C/1h) and only 5% MD shrinkage, significantly reducing internal short circuit risks caused by separator shrinkage at elevated temperatures while maintaining dimensional integrity during cell assembly and cycling
• Dry-Process Manufacturing: produced via advanced dry-process stretching technology (MSCS), delivering consistent pore structure, excellent chemical and thermal stability, and superior oxidation resistance for reliable long-term cycling and float charging performance
• Optimized Porosity & Permeability: features a porosity of 55%, Gurley value of 200 seconds, and average pore size of 0.064 μm, providing efficient ionic transport pathways while maintaining dendrite suppression and mechanical integrity
• Mechanical Strength Performance: provides MD tensile strength of 1055 kgf/cm², TD tensile strength of 135 kgf/cm², and puncture strength of 335 g, ensuring reliable processing during cell assembly and consistent performance across various battery formats
• Wide Application Compatibility: offers excellent resistance to acids, alkalis, and most chemicals with outstanding oxidation resistance, suitable for lithium-ion battery applications including coin cells, pouch cells, and cylindrical cells with compatibility across various electrolyte systems
