TAC film is an important part of optical film and polarizer, and its composition is very complicated, including plasticizer, co-solvent, wetting agent, slip agent and UV-resistant agent. Is one of the highest penetration of polymer materials.
Globally, the manufacturers that can really produce TAC films for high-end LCD TVs have only been Japan's Fujifilm and Konica Minolta for two years, and Fujifilm in particular is the leader.
It is understood that Japan's Fuji Film is a subsidiary of the Fuji Consortium, a global leader in TAC film, and has a strong accumulation of TAC film technology. At present, Fujifilm has three TAC film production bases in Japan, namely Fujifilm Kyushu, Kanagawa Plant, and FUJIFILM Opto Materials. They have a total of 17 production lines with an annual production capacity of 820 million square meters, accounting for approximately 59%.
Another Konica Minolta company in Japan officially launched TAC production of polarizers in 2000. In 2003, it merged with Minolta to form Konica Minolta. It has independent research and development capabilities and is a major global supplier of TAC films. .
At present, Konica has 8 production lines with a production capacity of about 300 million square meters, accounting for about 21% of global production capacity.
TAC film business of China SZXL Materials Technology Group
China's SZXL Technology's TAC membrane project started construction in September 2017. The total planned investment of the project is over 2 billion yuan. The company has obtained technical licenses for the production of a number of TAC functional membrane products through technical cooperation with Japan's Higashiyama. Introducing 5 internationally advanced Japanese coating production lines, with an annual output of 40 million square meters of functional optical film.
