Products Description of Methyl methacrylate CAS# 80-62-6
PMMA (polymethyl methacrylate) – the iconic "plexiglass" and top glass substitute. With high transparency, good impact resistance, light weight, low cost, and non-toxicity, its excellent optical performance (from uniform amorphous polymer structure) makes it widely used.
