Production of Nomex Insulation Paper to Be Expanded by DuPont JV in Japan

DuPont, makers of Nomex paper used in the manufacture of electric motors, generators and transformers, plans to significantly expand its global capacity for the electrical insulation product through a joint venture partnership with Nippon Paper Papylia in Japan. Commercial production is expected to begin in 2021 at a Papylia manufacturing facility that will be located in Yufutsu, Japan. 

“Nomex delivers unparalleled protection to millions of people and critical processes around the world and empowering endless possibilities,” said John Richard, global vice president and general manager, DuPont Safety & Construction. “DuPont is committed to creating sustainable innovations to help our customers and the world thrive.  Increasing our global supply to address the growing market is just one example of how we are delivering on our commitments.”   

Demand for solutions based on Nomex is being driven by innovation and growth trends in auto electrification, energy decarbonization, thermal protection and light weighting. Nomex paper is a key enabling technology in automotive electrification, insulating millions of EV electric drive motors globally, while also protecting critical components within the power electronics and battery systems, said Richard. 

Lightweight composites made of Nomex paper can be found in a wide range of aerospace applications, including cabin floors, overhead bins and bulkheads, landing gear doors and more. They have been a key component of the interior and exterior structure of commercial airplanes for more than 50 years. See
