What we call acrylic is actually the synthetic polymer of methyl methacrylate. It is an excellent replacement for glass in a lot of situations, like the picture frame being repaired here. It has an impact strength exceeding that of glass (meaning it is less likely to shatter), and has only half the weight. Its only disadvantage here is, it is much more easily scratched than glass. See the Wikipedia article on Acrylic glass if you want more details.
- Cutting small pieces of acrylic is not particularly dangerous, but be careful using the cutter knife.
- Cut acrylic may have sharp edges
