Entek product offering
Product offeringCore offering
ENTEK manufactures battery separators (polyethylene PE Silica for lead-acid batteries, Absorptive Glass Mat (AGM), and wet-process coated/uncoated lithium-ion separators) and extrusion equipment (co-rotating twin-screw extruders in QC3, HR3, and HT series, plus material handling systems and replacement wear parts). The company is the only separator manufacturer globally producing all three primary separator technologies and designs, engineers, fabricates, and installs its own production equipment with in-house engineering and machining resources.
Product overview
ENTEK is a global materials company offering three primary product lines: battery separators (PE SILICA, AGM, and Lithium-ion), extrusion equipment (twin-screw extruders in QC3, HR3, and HT series plus material handling systems), and replacement wear parts. ENTEK is the only company manufacturing all three primary separator technologies—polyethylene, absorptive glass mat, and lithium-ion. The lithium separator product portfolio includes coated and uncoated wet-process separators with various ceramic coating options (HTDS/HTSS, LTDS/LTSS) and uncoated variants (EP, EPH, EPX). The extrusion division produces twin-screw extruders for compounding applications in three series optimized for different production volumes. All products are designed and manufactured with in-house engineering capabilities.
