United States

ENTEK International today disclosed that it has completed its previously announced acquisition of NSG’s Battery Separator Division (BSD).

Larry Keith, CEO of ENTEK International, said "Today is an important milestone in the growth and evolution of ENTEK’s global business as we welcome BSD’s talented team to ENTEK, while also taking the next step forward in our growth and value creation strategy.”

The complementary combination of manufacturing footprints and product portfolios will enable ENTEK to support customers around the world with outstanding service as well as the industry’s premier offering of separator products for energy storage.  With this strategic acquisition, ENTEK becomes the only separator manufacturer in the world producing all three primary separator technologies (PE, AGM, and lithium-ion separators) for the global energy storage industry.  The transaction included all BSD manufacturing facilities in Japan and China for both polyethylene (PE) separator and absorbent glass mat (AGM).

ENTEK’s commitment to innovation and technology has availed the company with unique opportunities to support our customers’ growth globally while serving them with regional supply and service. Already recognized as the global market leader for PE separators in the automotive battery industry, this investment provides ENTEK with both capacity and expanded product offerings to help meet broader customer demands as well as enabling entry into new markets.

This acquisition is one of many exciting strategic initiatives currently underway at ENTEK including the expansion of the Indonesia manufacturing site, investment in specialty films at the Oregon campus, expansion of ENTEK’s equipment division and collaboration and investment at the Britishvolt gigafactory site in the UK.


For more than 35 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 batteries. Its separators are used in automotive, golf cart, and a wide range of industrial applications, and are also in great demand for products that require high energy or high voltage systems such as secondary batteries in portable devices and primary batteries in critical systems. ENTEK also manufactures the production equipment used to produce ENTEK’s high quality separator products.  ENTEK is a leader in the design, production and installation of twin-screw extruders and other production equipment to support our customers engaged in plastics compounding, including recycling, custom compounding, specialty sheet lines, and other products such as including bioplastics and other high demand goods that support the growing consumer demand for recyclable and biodegradable containers.
