While working during my undergraduate years for a plastic fabricator and supplier, a very new plastic was released for sale and it was called "Lexan", the brand name for this plastic. Lexan and polycarbonate are one and the same,... a cutting edge product back in the mid-sixties. I tried to see if I could crush a one inch OD x 1/16 wall piece of tubing in a vise, let's just say that I was lucky that day because I wasn't hit by the piece of plastic as it bounced off the "walls" in the shop.
(old guys always seem to have a story to tell, sorry)

Two 24x24 sheets come to $62 plus shipping against $51 delivered for Lexan from Aircraft Spruce. The first site that I found claims that it "approaches" the strength of polycarbonate. So Lexan's stronger. And less costly.
Meanwhile, I picked up an 11x14 sheet (5 winders worth) of .093 Lexan from the Home Despot. Comes to 6¢/sq in. and I don't like working with it as the backing sheet is semi-transparent and I can't see markings on it. The Bayer product (opaque white backing film) that Spruce sells is 4.4¢; the only problem is that I have to buy about 40 winders worth. If I live to 90, that's 5 winders a year. There may be a market for that. If not, it won't be the only thing my heirs will have to toss.
