ENTEK

Manufactures battery separators and extrusion solutions

Overview

ENTEK makes battery separators and extrusion equipment and services for energy storage and manufacturing customers worldwide. It focuses on lead-acid and lithium-ion separators, plus extruders and engineering services, all designed and built with in-house engineering, machining, and fabrication. Its products work by enabling safe, efficient energy storage: separators sit between battery electrodes to prevent short circuits while allowing ion flow, and extruders craft the polymer films and components used in separators. ENTEK differentiates itself through its vertical integration (in-house design, machining, fabrication), global reach across six continents, and a services-driven model that combines product sales with specialized engineering and support. The company aims to deliver reliable, best-in-class equipment and solutions through continuous improvement and decades of industry experience to meet the needs of battery manufacturers and industrial customers.
