Film-Related Technical Departments

Our Film-Related Technical Departments oversee the development of new products and processes involving high-quality, high-functionality films, including polyester film, polyolefin film, polyphenylene sulfide (PPS) film, and aramid film. Collaborative efforts to develop technologies for polymerization, film formation, and processing by our Japanese sites and seven overseas sites (in the US, France, China, Korea, Malaysia, Taiwan, and Thailand) allow us to quickly respond to customer needs, and to market products with outstanding performance, quality, and cost attributes. By actively promoting exchanges between engineers in Japan and overseas, we are systematically working to enhance and develop our fundamental technical capabilities.

Film Technical Dept. Mishima, Film Technical Dept. Gifu

The Film Technical Dept. Mishima and Gifu handle the development of new products and processes for Lumirror™ polyester film as well as MICTRON™ aramid film and TORELINA™ polyphenylene sulfide (PPS) film, which is produced worldwide solely by Toray. It also plays a role in supervising the development of polymerization technology used on the raw materials required in the production of Lumirror™ and MICTRON™. This department develops products for the wide range of applications for high-recording-capacity magnetic tape materials and high-transparency films used in flat panel.

Tsuchiura Plant Technical Sect.

The Tsuchiura Plant Technical Sect. develops capacitor applications and packaging/industrial material applications of TORAYFAN™ polypropylene film. Extremely thin films of thickness 3 micrometer or less are being used in capacitors for xEVs (hybrid and ordinary electric vehicles), and Toray is exploiting its technological and quality advantages to retain its top market share.

BSF Technology Dept. 1, BSF Technology Dept. 2

Toray was the first in the world to supply battery separator film (BSF) for lithium-ion batteries. Our BSF Technology Dept. 1 is in charge of developing new products and improving product quality of BSF SETELA™. BSF Technology Dept. 2 functions as a group of professionals, expert in the fundamental technologies of each process. It is in charge of developing processes and equipment including development of technologies for radical improvement of productivity.
