I have a real space limitation where every millimeter counts so I need to know if a 2mm polycarbonate will be at least as strong as 3mm acrylic if not stronger.
It's nearly unbreakable as long as it doesn't get exposed to certain chemicals, like diesel fuel or cutting oil. The stuff I'm using is 1/16", whatever that is in metric. You can hit it with a hammer and it won't crack. It should be very good in your application. Thin stuff you can cut with tin snips.
