cellulose triacetate การใช้
- Plastic enclosures include uncoated polyester film, uncoated cellulose triacetate, polyethylene, and polypropylene.
- The cellulose acetate and cellulose triacetate are film-and fiber-forming materials that find a variety of uses.
- The first instance of cellulose triacetate degradation was reported to the Eastman Kodak Company within a decade of its introduction in 1948.
- Their main use is to dye polyester but they can also be used to dye nylon, cellulose triacetate, and acrylic fibers.

- It also was the first major format to be released with only fireproof cellulose diacetate ( and later cellulose triacetate ) " safety film " base.
- In 1949 Kodak began replacing all nitrocellulose ( nitrate-based ) films with the safer, more robust cellulose triacetate-based " Safety " films.
- The cellulose triacetate membrane is prone to rotting unless protected by chlorinated water, while the thin film composite membrane is prone to breaking down under the influence of chlorine.
- The motion picture industry continued to use cellulose nitrate supports until the introduction of cellulose triacetate in 1948, which met the rigorous safety and performance standards set by the cinematographic industry.
- Starting with cellulose diacetate, this innovation continued with cellulose acetate propionate and cellulose acetate butyrate in the 1930s, and finally in the late 1940s, cellulose triacetate was introduced, alongside polyester bases.
- The cellulose triacetate base manufacturing plant of ORWO was sold to " Island Pyrochemical Industries ", Mineola, NY . The new company, located in the Chemical Park Bitterfeld-Wolfen, Germany, produces high quality TAC ( triacetyl cellulose, aka cellulose triacetate ) for the LCD polarizer market and the polarized sunglasses market.

- The crucial advantage cellulose triacetate had over nitrate was that it was no more of a fire risk than paper ( the stock is often erroneously referred to as " non-flam " : this is not true it is combustible, but not in as volatile or as dangerous a way as nitrate ), while it almost matched the cost and durability of nitrate.
