Mitsubishi resin develops functional film for OLED

Mitsubishi resin recently released a transparent gas barrier film "X-Barrier" with a water vapor transmittance of g/(M2 · d) and high barrier property. The film is barrier to oxygen, carbon dioxide and other gases. According to the requirements of users, we can customize the materials with the functions of real heat resistance, high temperature and humidity resistance, weather resistance and bending resistance of fixture description. At present, the samples have been evaluated and officially listed on July 1. In addition to flexible OLED displays and organic solar cells, the product is also expected to be used in cutting-edge medical and pharmaceutical packaging materials

Mitsubishi resin's new product "x-barier" and the original product "techbarier", the water vapor transmission rate and oxygen transmission rate of the existing film

the film is made by coating a thin layer of silicon oxide film (SiOx, x2) with a thickness of about 10nm on the surface of the substrate (PET, nylon, etc.) film by vacuum evaporation. By optimizing the film forming conditions of silicon oxide film, a fine film was made. Compared with the company's original "techbari needs to test different mechanical properties Er", the water vapor barrier rate of the new film is increased by 2-3 orders of magnitude (Figure). This figure "belongs to the capacity plan of nearly 400000 tons, the highest level in the world" (the company)

applying this product to new generation displays such as OLED panels, electronic paper and organic solar cells can greatly improve the reliability of components. It can also realize flexible panel. In addition, it can also roll to roll production, significantly reducing costs

the company plans to strive for sales of 5billion yen in three years, including cutting-edge medical and pharmaceutical packaging materials. In addition, the development will continue in the future. Li 7. The accumulator will strive to improve the water vapor barrier by another 1-2 orders of magnitude in 3 years
