ENTEK, Separindo and NSG Group Announce Joint Venture

ENTEK, Separindo and NSG Group have reached an agreement for NSG to join the previously formed ENTEK-Separindo joint venture for manufacturing and sales of polyethylene (PE) separators for lead-acid batteries.

In the rapidly expanding Asian market for automotive flooded lead acid batteries, the demand for Idling Start and Stop (ISS) batteries is expected to grow significantly due to the needs for fuel efficiency and the reduction of carbon emission. ENTEK and NSG Group are technology leaders in the ISS batteries for which PE separators play a key role in ensuring the higher battery durability and performance to withstand frequent charge/discharge.

NSG Group’s investment in the joint venture company in Indonesia is aimed at upgrading its product supply capability in the expanding Asian market by partnering with ENTEK, the world’s leading producer of PE separators, to generate a synergy in sales, manufacturing and research and development.


For more than 30 years, ENTEK has been an innovator and leading world-wide designer and producer of highly reliable microporous polyethylene battery separators for lead-acid and lithium-ion batteries. Its technology is used in SLI, golf carts and wide range of industrial applications, and are in great demand for products that require high energy or high voltage systems such as secondary batteries in portable devices and as primary batteries in critical systems. ENTEK also manufactures turnkey production Extruder systems, twin-screw extruders, and components. It is a leader in the extrusion of natural fiber-plastic composites (wood decking), pelletizing, custom compounding, specialty sheet lines, and products for other markets including food and medical applications. ENTEK is headquartered in Lebanon, Oregon, with facilities in the United Kingdom. Its products are sold through its sales offices and distributors worldwide.
