ENTEK Lithium-Ion Separators is a leading producer of polyethylene separators used in lithium primary and secondary batteries, with end uses ranging from portable devices to vehicles. ENTEK Separators are a biaxially-oriented, polyolefin separator that is manufactured by a unique polymer processing technology. The separator is largely composed of ultrahigh molecular weight polyethylene with an ultrafine, interconnected pore structure. Key performance characteristics include good mechanical properties, chemical inertness, and controlled shutdown with a high meltdown temperature. ENTEK distinguishes our product line based upon porosity of the separator and product thickness for a given application.
