[QUOTE="BrianChia, post: 4099481, member: 576132"] Whoah, don't get too excited about Lexan, guys. Here is a brief lesson on "bullet proof" stuff. Lexan is simply a brand name of polycarbonate, which is a simple clear plastic. Much like Plexiglas is a brand name of acrylic. Either material can be used in manufacturing bulletproof glass although polycarbonate is typically tougher and more impact resistant. [B]The material itself is not bulletproof at all. It is way too SOFT. [/B] Bulletproof glass is made of temepered glass laminated to a clear plastic, either acrylic of polycarbonate (usually the latter) in multiple layers.
