Heat resistant transparent resin sheet and thin film can be used for display panel

[Nikkei BP news] Showa electrician developed a hot deformation temperature of up to 250 degrees above the transparent heat-resistant resin sheet and film. Light transmittance as high as 90%, is used as a substrate of glass plate substitutes and flexible display in the display area.

Details of the material did not disclose, Showa electrician only said that the use of "independent development of the resin" (Showa electrician IR PR room). Is widely used as a heat-resistant transparent resin PEN (polynaphthalene two terephthalate) resin with deformation temperature of 230 DEG C, and the heat resistance of the product not only has better, and resistance to acid, alkali and organic solvents is also very good. Therefore, in the current display manufacturing process, which is used as substitute for glass plate, can reduce weight, improve the safety monitor. In addition, the surface hardness is as high as 3H. Will start from 07 November to supply 230mm * 230mm * thick 1mm sample sheet.

The thickness of the transparent resin film with the same material is 100 m, and the coefficient of linear expansion is only 20ppm/. The heat resistant temperature is 200 DEG C, and the ITO transparent electrode can be formed. Can be used as the base material of flexible electronic paper and organic EL panel. Monomer free gas (Gas Barrier), but in the future also plans to supply the performance of the product with gas resistance, the film is scheduled to start in 08 years supply samples.

The company will be in November 6th to 9 at the 300mm International Exhibition Center in Tokyo, INCHEM TOKYO (ADvanced MATerials Show), on display 500mm * 500mm sheet and wide thin film.
