 A key material in the production of robust LCDs

Optical film is a thin film with various optical characteristics that is used in the production of FPDs (Flat Panel Display) such as LCDs, PDPs, OLEDs, etc. It is usually applied to displays in sheet form. Hyosung Chemical’s Optical Film PU manufactures TAC (Tri-Acetyl Cellulose) film, which protects the polarizing film, a component of the LCDs fitted into TVs, monitors and laptops to strengthen the display part. As the polarizing element - which is critical to polarizing film - is a thin, fragile film, it is protected by a transparent yet robust TAC film.

 Korea’s first TAC film to be made with high technology

As TAC film needs to be physically strong, the use of heat-resistant, moisture-resistant and optically isotropic, high technology is a must. Hyosung Chemical’s Optical Film PU has independently developed and produced TAC films for the first time in South Korea. Since establishing a production plant for TAC film for LCDs in Ulsan in 2009, the company has been able to mass produce TAC films, an unprecedented achievement in the country. Furthermore, having established TAC Plant 2 and an additional TAC plant with a (combined?) capacity of 60 million ㎡ in Oksan in 2013, the company now boasts a total annual production capacity of 110 million ㎡. Notably, TAC film is recognized as an environmentally-friendly product as it is made from cellulose derived from cotton.

The Optical Film PU has recently advanced into China, the world’s largest display market, in a drive to expand its sales, and is developing new films based on TAC film technology with a view to penetrating various optical film markets.
