Richard,
Not meaning to be rude, but both you and your "expert" are wrong.
Lexan is the brand name of polycarbonate plastic manufactured by
GE. Acrylic plastics an example of which is Plexiglas (which is
manufactured by Atoglas), are entirely different. San Diego Plastics
sells all kinds of plastics on the web and has pages devoted to each.
See: <http://www.sdplastics.com/index.html>. Waggoner Plastics
also has information on various plastic stocks; See:
<http://www.waggonerplastics.com/products.htm>.
Some subjects, like copyright law or what boat to tie to the roof
of your Hundai, invite endless argument. This thread does not. Facts
is Facts,
Respectfully,

Lexan/acrylic must be a blend, as those are two different animals. I
know they blend lexan (or polycarbonate, at least approx. same thing)
into abs (ex: Bayblend) to toughen it up. Lexan by itself is very
tough.

Mark et al.
yes on all counts. it does scratch slightly easier than glass, but if
youfollow the proper cleaning methods, it shouldnt be a problem. i bought
some for my auto racing projects and as i recall it is a little less than $2
per sq ft. it is a bit the opposite of silly putty, if you bend it very
slowly past 90 degrees, it may break, but shoot it with a gun and it will
just deform, not shatter. very good stuff.

Richard,
Isn't polycarbonate the stuff replacing glass for spectacle
lenses? When made for that it is:
light
thin
very self-supporting
shatterproof ?
very clear ( w/ no UV degradation )

go to somewhere that specializes in plastics, i go to Plastic supply in
westbrook maine. myexperience has been that the people who sell plastics can
recommend exactly what will work.
as to the 3/32ths properties... well, dont tell anybody, but my first hobby
is my race car, and the windows will soon all be made of 3/32" polycarb. a
common weight saving/safety mod in racing) my brother shot a supported piece
with a .22 and it did not puncture it (deform yes, puncture no). you plan to
pull any 007 stunts?
note: polycarb is NOT lexan/acrylic

I live in Maine. nobodydoes anodizinghere,no mandrel benders, no
powdercoating. but in the yellow pages i found one "plastic supply co." they
everything, and know what they are talking about.i would recommend some 3/32
polycarbonate for windows, just follow the cleaning instructions on the paper
protection layer before discarding it.
Richard
p.s. much lower prices than home depot for the same product
powdercoating. but in the yellow pages i found one "plastic supply co." they
everything, and know what they are talking about.i would recommend some 3/32
polycarbonate for windows, just follow the cleaning instructions on the paper
protection layer before discarding it.
