It is fragile since it is based on cellulose. When cellulose diacetate deteriorates, it shrinks and releases acetic acid causing vinegar syndrome.
Cellulose diacetate has been used to make fabrics, membranes, filaments, and many consumer products. From 1922 to 1957 it was used to make film stock, mainly in smaller formats such as 8 mm, 16 mm, 35 mm, and 70 mm. It has also been used in seed coating applications.[1]
