Polyester Film Deterioration Characteristics. Polyester film has much greater chemical stability than cellulosic films, and it has virtually no visual deterioration characteristics inherent to the film base itself; However, black-and-white polyester film may undergo characteristic silver image deterioration (discoloration, silvering, fading

This is potentially disastrous to your home movies, cine film, videos and even TV and film archives if they are not stored correctly to protect them from fungal infection. As acetate film decays, it shrinks, loses flexibility, curls, and wraps. Safety motion picture film (so called because it is not flammable like nitrate base film) was almost always made of cellulose acetate plastic. A key issue in preserving this type of film is controlling the form of decay known as "vinegar syndrome." When working with a collection of legacy analog photography, curators and handlers will almost certainly encounter safety film deterioration and its ravages as a commonplace occurrence. The results are always startling in that their discovery may represent the permanent loss of a unique asset.

When the base of safety film starts to decompose, we call it “vinegar syndrome” and the entire film may start to curl, warp and shrink. Vinegar syndrome is the chemical reaction that occurs when acetate deteriorates, which causes deacetylation and the formation of acetic acid, producing a distinct vinegar odor.

Cellulose nitrate film stock was in commercial use through the early 1950s, when it was replaced by cellulose acetate plastic "safety film." student year 3 project. try not to slit your wrist please 2018-08-23 · Three Stages of Nitrate Film Decay. Some online resources break down the phases of nitrate film decomposition even further, but consider these three main stages for now. Stage 1: Orange film discoloration and fading images. Stage 2: The film becomes smelly, sticky, and appears bubbly or foamy. Rolls of third-stage film have annular portions which are soft, contain gas bubbles, and emit a noxious odor easily recognizable. In the fourth stage of deterioration, the entire film is soft, its convolutions welded into a single mass and frequently its surface is covered with a viscous froth.
