“Our goal is to be the best supplier to our customers, and the best customer to our suppliers.”

–James Young, ENTEK co-founder

ENTEK is synonymous with some of the world’s best lead-acid separators, lithium-ion separators, extruders, and engineering services for the battery and extrusion markets. We operate on six continents; astronomical growth for the simple lead-acid battery separator company James Young and Pete Johnson founded in Lebanon, OR in 1984.

Our intimate knowledge of both the design and manufacturing of separators spurred the introduction of our high-speed co-rotating twin-screw E-Max extruder in 1998—recognized as the fastest to install and easiest to operate extruder on the market.

In 2001, our first lithium-ion battery separator line expanded our reach in Asian markets, delivering a quality product at a market-leading price. Our success here is fueled by consistently living our core values of respect, integrity, commitment, and innovation.

From state-of-the-art separators and extruders, to 360° engineering and support for all of it, ENTEK’s commitment to non-stop innovation and attention to customer service keeps production lines humming. With plants in both Lebanon, OR and Newcastle UK, we are set up to make sure that a world at work has what it needs to stay at work, 24-7.

Markets We Serve

ENTEK sells lead-acid separators, lithium-ion separators, extruders, and engineering services on six continents. We design and build our battery separator lines, extruders, and parts with our in-house engineering, machining, and fabrication resources. Combining best-in-class equipment with our pursuit of continuous improvement manufacturing gives our customers the full benefit of over 25 years of experience in these industries.  We believe that our success is possible only if we do our utmost to make our customers successful. You will see and feel this commitment from the first day you do business with ENTEK.

Research & Development


ENTEK’s Separator Technology Center leverages extrusion technology from our sister company, ENTEK  Extruders, to provide next generation separator solutions for energy storage applications.

Promotes Breakthrough Technology

The facility supports product development and innovation. It allows small-scale production of the newest  designs for verification and validation prior to full-scale production.

Collaboration and Partnerships

Through our collaborative relationship with one of our primary customers, ENTEK was a recipient of a  multi-million dollar grant from the United States Department of Energy under the American Recovery and Reinvestment Act (ARRA). This award was used to build domestic manufacturing capacity for advanced separators for hybrid and electric vehicles.


Our dedicated R&D team, with a full spectrum of scientific backgrounds, enables ‘outside-the-box’ thinking to produce novel approaches to design.

Customer Based Design

Listening to our customers’ needs, we develop products that allow them to continue to be market leaders in their respective fields.

Community Commitment

ENTEK’s commitment to service is rooted in its founders’ belief that being the “best supplier to our customers” extends beyond products and services to encompass community stewardship. It was this philosophy that prompted employees to start an annual ‘Coats for Kids’ campaign in our earliest days, whose sole purpose was to provide coats to underprivileged children in the community. That effort continues to this day and has expanded into an annual tradition that to date has provided a winter coat to thousands of local school kids.  As a natural evolution of this program, a non-profit has been formed to expand its current scope into other areas.

ENTEK encourages its employees to participate in community service projects by offering paid time off for community involvement, including programs it sponsors, such as a Thanksgiving Food Box drive that provides complete meals to families in the community.

We are a premier sponsor of Lebanon’s annual Strawberry Festival and a major supporter of the Lebanon Boys and Girls Club, Lebanon Soup Kitchen, and Lebanon High School’s Turf and Track program. We also provide matching funds to employees participating in The American Cancer Society’s Relay for Life.

And while we are constantly changing and growing, the core of who we are always stays the same.
