Showa Denko completes pilot plant for heat-resistant transparent film

Showa Denko K.K. (SDK) has completed, within the premises of its Oita Complex, a pilot plant for its new heat-resistant and transparent film SHORAYALTM. SDK will start sample shipments for use in displays, including touch screens, and accelerate marketing activities in preparation for the start of full-scale commercial shipments. With the completion of the pilot plant, SDK can supply film samples in the form of sheets, in addition to rolls. Since samples are to be provided in accordance with actual manufacturing conditions at customers, SDK expects that the process for commercialization of SHORAYALTM will move quickly. The film has been developed on its proprietary resin technology for glass lens applications. The film has high transparency necessary for optical films, and high heat resistance required when displays, including touch screens, are produced. Demand will continue to grow for displays of smart phones, tablet PCs, and other types of mobile electronic devices. Furthermore, these displays will be continuously improved in terms of visibility, durability and lightweight. In this context, SHORAYALTM has great potential for outstanding performance and cost advantages. Major characteristics include: a) Heat resistance: Can be used in high-temperature processes of up to 250 degrees C b) Optical characteristics: High light transmittance of 92% (comparable to that of glass); Low double refraction c) Chemical resistance: High resistance to acids, alkalis, and organic solvents d) Surface characteristics: High surface hardness of 3H or more (in pencil hardness)
