The characteristics of the Teijin materials have made it possible to achieve the world's lightest weight portable display, weighing approximately 325g, and with its thinnest point being approximately 3.9mm.

Tenax™ TPCL intermediate, used for the VAIO Vision+™ housing’s top and bottom layers of the sandwich construction, is a sheet-like material made of woven carbon fiber impregnated with thermoplastic resin. It is lightweight, resistant to heat and impact, strong and rigid, and also meets flame retardancy requirements for electrical products. In addition, Panlite® Sheet, made from PC resin and used for the middle layer, has excellent dimensional stability, light weight and impact resistance.

Reduced CO2 and easier manufacturing Tenax™ TPCL is used for the housing (top & bottom layers) and Panlite® Sheet for the middle layer Conventional housings use metal parts for assembly, which need to be installed during the manufacturing process. However, the housing of the new displays, which has a structure that sandwiches Panlite® Sheet between Tenax™ TPCL layers, achieves the shape and strength of the connections necessary for assembly without the need for metal parts. This material solution makes it possible to manufacture complex, three dimensional shapes in a single molding step, which helps reduce the number of steps required to manufacture the housing, and also cuts CO2 emissions. The Teijin Group aims to become a "a company that protects the global environment," embodying its long-term vision of becoming "a company that supports the society of the future," and will continue to utilize a wide range of highly functional materials to provide solutions in a variety of fields.
