ENTEK EPX is an extremely high porosity separator designed to provide ultra-low impedance for specialty battery applications. It has also been used as a thin film (7-12µm) PE substrate in various ceramic and PVDF coating applications. Ceramic coated separators provide outstanding high temperature dimensional stability in HEV and EV applications while PVDF coated separators are commonly used in large format Li-ion polymer cells.
