Vinegar syndrome

edit

The vinegar syndrome article says its a problem with cellulose triacetate but this article is saying it applies to Cellulose acetate. Does it apply to both? Plugwash 11:05, 22 September 2005 (UTC)Reply

History

edit

The history section seems to have some grammatical errors. 9:38, 13 August 2011 (UTC)

The section about Mazzucchelli Spa seems very out of place both in content and its placement in the timeline. — Preceding unsigned comment added by 69.21.224.61 (talk) 06:56, 18 December 2014 (UTC)Reply

Fiber

edit

"These "cellulosic fibers" have passed their peak as cheap petro-based fibers (nylon and polyester) and have displaced regenerated pulp fibers."

This sentence is not at all clear. These fibers are not petrol based. What is the author trying to say here? Targa86 20:10, 2 October 2006 (UTC)Reply

That those cellulosic fibers are now substituted by the petro-type. The "and" after the closing parenthesis is superfluous and/or a word like "appeared" was forgotten before the "and". 88.172.184.82 (talk) 21:39, 14 January 2010 (UTC)Reply

More Uses

edit

100% Cellulose Acetate is used in KEM playing cards as well. They are supposed to be the standard in playing cards, and are very good quality. 70.111.224.85 03:03, 17 January 2006 (UTC)Reply

Screwdriver handles

edit

The handles of Craftsman screwdrivers are made of cellulose acetate. Many who have used these screwdrivers probably remember their distinctive scent. Just saying. This isn't my area. Camenae (talk) 00:16, 6 December 2009 (UTC)Reply

Compost?

edit

According to the article on cigarette filters: cellulose acetate is not biodegradable. Yet in this article it is mentioned that they can be "composted or incinerated." So how can you compost a nonbiodegradable substance?

I believe that the tests for biodegradability require decomposition within a particular timeframe under specific conditions, and that some types of wood would fail the biodegradability tests simply by being too slow to biodegrade. The same is true of cellulose acetate.

P.S. I am not a chemist. But as Camenae correctly pointed out, this material has a scent. I must believe that anything that has a scent will degrade to some extent. — Preceding unsigned comment added by Mea (talkcontribs) 14:03, 5 June 2011 (UTC)Reply

Photodegradation

edit

Paragraph states that photodegradation occurs below a certain wavelength and is enhanced by titanium dioxide. Yet titanium dioxide is a know UV blocker. Is this paragraph correct?Longinus876 (talk) 08:15, 2 March 2018 (UTC)Reply
