Lexan

[ominously]

I did a search and couldn't find much on it, but using 1/4" lexan: is there problems with warping, yellowing, clouding, and if so, what are the causes and fixes (if any) that you may be aware of?

How does heat, moisture, or other things impact it in your experience?

Mike, Lexan is used in a variety of areas where this material has to endure stresses which far exceed the problems you are concerned with. It's applications include the aerospace and automotive industries where temperature extremes, heat, moisture, and UV exposure is a constant to these products.

Lexan is a product of GE Plastics and here is the link to the Lexan page:

On the bottom of the right hand column you will be able to chose literature that will answer all of your questions and concerns.

Excellent! Now that I know that I thik I will ask for the rest of the pieces this person had and start making things with it a little more zealously (is that a word? - perhaps enthusiastically instead).

Found this on Wiki.

Lexan leaches bisphenol A, a chemical that some studies linked to cancer. These studies indicate exposure to low levels of BPA causes a range of serious health effects in laboratory animals.

An expert panel of 12 scientists has found that there is "some concern that exposure to the chemical bisphenol A in utero causes neural and behavioral effects," according to the draft report prepared by The National Toxicology Program (NTP) Center for the Evaluation of Risks to Human Reproduction.

Lexan is nice and it can stand up to high heat,stress,gunfire,and anything mother nature can throw but it has some hard chemicals in its makeup. I stick to glass. Glass is cheaper and fun to smash.

Thankfully, my schedule hasn't permitted much more than minimal building and destruction, but not with the roll of lexan I now own. I suppose it will be fun stuff to make something out of, but perhaps I'll just scrap it (I'm thinking protective covers for surfaces, or perhaps a really nice clear sub box for some twelves...)
