Polycarb is impact resistant at RT, but not so much if you freeze it. So, not for cold demos.
The larger the panel, the more it will flex. So, depending on how you intend to support it, you may need to go as thick as you can afford.
I have used thinner than 3/16 with success for stopping projectiles. However, that's not ballistics grade. If you want that level of protection, you'll need a pane that's rated as such.
Thank you,

Hi everyone -
We are putting up plexi shields to that clamp on the bench to divide them in half so students can work at opposite ends of the bench, facing each other. My department
chair just suggested that we order some of them in a "thicker plexi" so they can be repurposed as demonstration shields, something I have been advocating for for several years now. Looking online, the shields I am finding are listed as "thick polycarbonate"
(one site specifically said 3/16 in) or "acrylic". Is there something more specific that you can recommend? Members of my department really like to push beyond the boundaries of what I consider safe for chemistry demos, so I would love to protect students
however I can.
Thank you,
