Films and Film Products
Research Laboratories

Laboratories established 1963 to conduct basic research at the Toray film business.
Bolstering progress in this key field, research is advanced into base films and processed film products.

Toray is the creator of LUMIRROR®, the first biaxially oriented polyester film commercialized in Japan, which with the polypropylene film TORAYFAN® leads the world in high-performance and function. Also developed and commercialized here were the world's first biaxially oriented polyphenylene sulfide (PPS) film TORELINA® and the aramid film MICTRON® - two more materials boasting revolutionary characteristics.
The Laboratories has forged pivotal progress in the progressive R&D of film. For example :① For the film-making process, technology to produce the world's thinnest film, followed by perfection for use in capacitors helping to downsize various types of electronic devices and instruments. In addition, the laboratories have developed and are working to expand the applications of: ② Low specific gravity, high-whiteness film for LCD displays in which numerous fine voids are formed by combining polymer alloy technology with drawing technology, ③Polyester film for molding, employing polymer fine structure control, ④ Base film for high-density magnetic tape made of highly heat-resistant polyester employing nano-order polymer alloy technology, in which fine surface protrusions are controlled using our unique film compounding method, ⑤ Formation of uniform and precise through pore by unique technology, and ⑥ Substrate films for displays such as hard-coat and prism, provided with outstanding transparency and adhesion using special surface treatment technology.

  • Microporous aramid filmMicroporous aramid film
    Through our unique design technology for highly heat-resistant polymers and pursuit of technology for control of nano-phase separation structure, this material achieves heat-resistance and flame retardance, with little change in shape even under high temperatures of 200ºC. It also has high porosity and a uniform pore structure.

As a result of further deepening and developing Toray's nanotechnology, we have recently developed PICASUS®, a nano-laminated film which achieves a metallic luster by laminating multiple polymers on the nano-order; ultra high-durability PET film which realizes dramatically improved durability via our unique polymer design technology and film structure control technology; self-repairing coating film with fingerprint resistance and the ability to instantly repair scratches thanks to self-organization technology and polymer viscoelasticity control of the coating layer surface; and microporous aramid film which achieves heat-resistance at the highest level in the world by combining our unique polymer technology with nanotechnology. We are working to expand the applications of these films in fields such as information andcommunications, environmental technology, resources/energy, and life innovation, and our state-of-the-art research results have been highly acclaimed from all corners.
