Polycarbonate (trade name Lexan) is the ideal material. Better impact and crack resistance than acrylic. Polycarbonate scratches more easily, but it's worth the impact protection, hands down. Check out this video comparing the two: https://youtu.be/Hsls5ZPCUnE

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,Heather Wages ZimmerScience DepartmentOutreach TeamNorris House AdvisorMilton Academy
