Re: Lexan (polycarbonate)

Hi,

Lexan is not brittle at all.

Thick lexan is used for bulletproof enclosures...most gas stations in
and around downtown Houston have 1" thick lexan boxes around the
store clerk. 

I have shot 1/2" lexan with a .22 rifle - instead of shattering, the
bullet just sticks in the plastic. Amazing stuff.

A good test to discern between plexiglass or lexan, is to break off a
small piece and use epoxy on it. After a day or two, epoxy will break
loose from plexiglass. 

I had a primary coil once, where I epoxied lexan supports onto a
plexiglass baseplate. After a couple of weeks, the entire primary
coil - supports and all - became separated. It was pretty funny.

Anyhow, epoxy will never come off of lexan after it has hardened.
Makes things very strong, maybe even bulletproof!

Take care,
