For over 1,300 years, Sekine Seal Industrial has been a Japanese manufacturer of specialty functional paper, rooted in the traditional papermaking of Ogawa Washi. Today, we apply that heritage to advanced materials for electric vehicles and automotive systems, including heat-resistant and thermally conductive insulation paper, and non-metallic to flame-retardant sealing and gasket materials.
