Acrylic and plexi aren't the same thing

Um, sorry, but WRONG! Ever looked at a piece of Plexiglas? It even says it's acrylic on the label. Plexiglas is simply one of many brands of acrylic forms actually made of polymethylmethacrylate resin. Other brands include Perspex and Lucite. Acrylics are available in two forms, extruded and cast. Extruded acrylics tend to be more flexible, have tighter thickness tolerances, but have less clarity than a cast acrylic.
