M-aramid Coated Isolation Film 9um PE 3um Aramid

This product is designed for advanced lithium-ion battery applications, featuring a 9 µm polyethylene (PE) substrate coated with a 3 µm meta-aramid layer. The aramid coating provides exceptional heat resistance, oxidation stability, and improved electrolyte wettability, while maintaining a low specific gravity and a porosity of approximately 37%. These characteristics enhance manufacturing efficiency, battery safety, fast-charging capability, and cycle life. The separator is intended for use in 3C electronics, electric vehicles, and energy storage systems. Proper handling (aramid side facing out, airtight packaging, and cling film for unused portions) is required to preserve its performance. This solution offers a balanced combination of thermal stability and electrochemical reliability for high-energy-density battery designs.
