Applications
We introduce the major applications of cellulose acetate.
TAC film
Protective films for LCD polarizing panels
Cellulose triacetate, which has been used as the base material for photographic film, is used in optical films such as protective films for LCD polarizing panels used in LCD TVs, notebook computers, and mobile phones. Cellulose acetate also holds great potential in light of advances in optical imaging technology.
Cellulose Acetate plastics
Glass frames
Cellulose acetate plastics are made from natural cellulose such as wood pulp and cotton linter. Therefore, the sheets are gentle to the skin and less allergenic.
Compared to petroleum-based resins, the sheets are highly transparent, so vivid colors can be expressed. Processed parts made with the material are easy to polish, and cut, as well as bend and twist because it starts to deform at about 60 ℃, making it ideal for processing the unique curves of eyeglass frames.

Cosmetics & Healthcare
Membranes for water treatment
Water treatment such as water purification and seawater desalination
The surface of cellulose acetate membranes with excellent hydrophilicity are resistant to dirt, and can maintain high permeability in a stable manner.
The "Cellulose acetate hollow fiber ultrafiltration membrane module" has been adopted at many water purification plants, and contributes to creating high-quality drinking water.

Acetate fibers
The textile of acetate fiber has a silky luster and feel, is superior in water absorption and hygroscopicity, providing an optimum material for comfortable clothing. In addition, acetate tow, a mesh structure composed of acetate fibers, is used in cigarette filters.
Film base for photographic and X-ray films
In the 1950's, the material for film base was replaced by cellulose acetate with the aim of non-flammability.
The film is suitable as a base film due to its excellent transparency and surface smoothness.
