cellulose triacetate

In the 1930s, film manufacturers introduced "safety film" with a cellulose triacetate plastic base.

Beginning in the 1980s, there was a great deal of focus upon film stability following frequent reports of cellulose triacetate degradation.

In cellulose triacetate membrane systems, a carbon postfilter is needed to remove chlorine from the final product, water.

Content: Compares the stability of cellulose triacetate and polyethylene terephthalate base films under various conditions.

It is distinguished from cellulose acetate and cellulose triacetate.

Content: This article evaluates the effectiveness of microenvironments to control the stability of cellulose triacetate base film in roll form.

These drawbacks were eventually overcome with the launch of cellulose triacetate base film by Eastman Kodak in 1948.

They were manufactured from a mix of cellulose triacetate and polyester making them shiny on the outside, with distinctive combinations of colours.

Eastman Kodak formerly manufactured cellulose triacetate.

TR-95-011, provides for the duty-free entry of woven fabrics containing 70 percent or more by weight of cellulose triacetate filaments.

Content: Discusses the current results of a world-wide test into the use of molecular sieves in cellulose triacetate film cans.

Their main use is to dye polyester but they can also be used to dye nylon, cellulose triacetate, and acrylic fibers.

Content: Describes experimental procedures used to examine the effects of various parameters on film degradation and several types of possible stabilisers for cellulose triacetate.

The cellulose acetate and cellulose triacetate are film- and fiber-forming materials that find a variety of uses.

Content: Outlines various external parameters that may have an effect on cellulose triacetate degradation, eg temperature, humidity, plasticiser, iron etc.

It also was the first major format to be released with only fireproof cellulose diacetate (and later cellulose triacetate) "safety film" base.

The first instance of cellulose triacetate degradation was reported to the Eastman Kodak Company within a decade of its introduction in 1948.

Plastic enclosures include uncoated polyester film, uncoated cellulose triacetate, polyethylene, and polypropylene.

Gives experimental results regarding degradation over time of both cellulose triacetate and polyester, and regarding the effect of storage conditions on life expectancy.

Content: Discusses the storage of degrading cellulose triacetate film and life expectancies of two types of "archival" film.

Cellulose triacetate superseded nitrate as the film industry's mainstay base very quickly: Kodak announced the discontinuation of nitrate manufacture in February 1950.

Once wet enough the tablets will release acid that accelerates degradation to around two weeks (instead of using cellulose triacetate and besides of cigarette smoke being quite acidic).

Content: This article looks at the two principle mechanisms of polymer degradation and presents data showing the relationship between peroxides and metal ions in cellulose triacetate motion picture film.

The cellulose triacetate base manufacturing plant of ORWO was sold to Island Pyrochemical Industries, Mineola, NY.

Content: The first chapter, "the Base," discusses the methods of manufacture of various base types (particularly cellulose diacetate, cellulose triacetate and mixed esters) and their properties.
