NKK separators boast an overwhelming share of the market
Our separators for aluminum electrolyte capacitors were developed based on the technical data and manufacturing know-how we have accumulated since our founding and these have gained an overwhelming share of both the domestic and foreign markets with the electric double layer capacitor separator capturing a high global share. We will continue to challenge the future by meeting our user needs by continuing to create new products.
