Absolutely. Just like steel or any other material, the specific chemical makeup, structural makeup, casting process, etc. etc. can alter a plastic to a whole range of different strengths, toughness, creep resistance, clarity, heat resistance, and so forth. I'm sure there are hundreds of types of Plexiglas.
Don't confuse this with Lexan, which is a trademarked brand of polycarbonate. Same general idea, though - many different grades.
Very good link.
