Thin Translucent Red?

[Brent Vander Weil]

In eading the MSDS ( I am not a chemical engineer so I have to ask) it says the following-

Decomposition Products
Carbon Monoxide, Carbon dioxide, acetic acid, water.

Now I know this is not the same acid variety that would be produced by lasering PVC, but is this of concern? Why or why not?

Acetic Acid is harmless. That is what you smell in vineger, Silicone RTV, and lots of other products.

[Tim Goldstein]

The danger of acetic acid depends on the strength.

From Wikipedia:
Concentrated acetic acid is corrosive and must therefore be handled with appropriate care, since it can cause skin burns, permanent eye damage, and irritation to the mucous membranes. These burns or blisters may not appear until several hours after exposure. Latex gloves offer no protection, so specially resistant gloves, such as those made of nitrile rubber, should be worn when handling the compound. Concentrated acetic acid can be ignited with some difficulty in the laboratory. It becomes a flammable risk if the ambient temperature exceeds 39 °C (102 °F), and can form explosive mixtures with air above this temperature (explosive limits: 5.4%–16%).
The hazards of solutions of acetic acid depend on the concentration.
Solutions at more than 25% acetic acid are handled in a fume hood because of the pungent, corrosive vapour. Dilute acetic acid, in the form of vinegar, is harmless. However, ingestion of stronger solutions is dangerous to human and animal life. It can cause severe damage to the digestive system, and a potentially lethal change in the acidity of the blood.

My guess is that it would be a low concentration. Main point is just because something is safe in one setting does not mean it is always safe.

Doing some filing and sorting, and happened to come across another "maybe" from Multi-Plastics Inc.

http://www.multi-plastics.com/PDF%20files/solatuf.pdf

It is Modified acrylic avail in .020 (and more). They SAY you can choose translucent colors and they SHOW colors on the website, but the real test is asking for a quote . . .

But if they can't supply in red maybe you can process it with paint/screen print etc to convert to red or give you some tips on how to color.

It's "chlor" that you have to watch out for on MSDS sheets, hydrochloric acid is what the lasering of PVC will create.

I have cut acetate before with no trouble, just haven't found anything but clear.

Richard, I'll check that source out too. Thanks.
