an ester of acetic acid; used in fibers and fabrics; photographic films and varnishes
Obtained by the action of acetic anhydride on cellulose, usually cotton, in the presence of glacial acetic acid. It forms the basis of the non-inflammable celluloids, commonly known as "safety film." Films prepared with it fuse and char, but will not burn. (Jones, 96) When it deteriorates acetic acid is produced, a process that once started can be slowed but not stopped. Deteriorating film should be segregated from the collection and placed into cool, dry storage and plans made to have it reformatted onto polyester.
a tough thermoplastic made from CELLULOSE in the form of cotton lintyers, treated with acetic acid and acetic anhydride. Previously used as aircraft dope during WWI, now used for many domestic mouldings such as toothbrush handles & packaging film.
Used in the context of lamination (see below) it is the plastic film between which a document to be laminated is placed and which bonds with paper when heated.
small plastic fibres that create a trap for smoke particles in cigarette filters.
A type of resin made from the reaction of acetic acid or acetic anhydride with a cellulose base (cotton and/or wood pulp).
Cellulose acetate is a plastic that replaced cellulose nitrate as a base for photographic negatives and motion picture film. Early audio recordings, microfilm/microfiche and X-ray film also consisted of cellulose acetate. It is known as "safety film" because it is far less flammable than its predecessor (cellulose nitrate film). Cellulose acetate was introduced as early as 1909 but did not entirely replace cellulose nitrate until the 1950s. Its deterioration gives rise to the euphemistically named "vinegar syndrome" because of the characteristic odour of the acetic acid released as a by-product.
a class of resins made from a cellulose base. Either cotton linters or purified wood pulp, by the action of acetic anhydride and acetic acid.
Paint and varnish binder, made from a sulfuric or acetic reaction with cellulose fibers
A tough cellulose material used to impregnate cotton insulation.
Cellulose acetate, first prepared in 1865, is the acetate ester of cellulose. Cellulose acetate is used as a film base in photography, and as a component in some adhesives; it is also used as a synthetic fiber.
