Products Description of Methyl methacrylate CAS# 80-62-6

Polymethacrylate, full name polymethyl methacrylate (PMMA), is an important optically transparent plastic with the advantages of high transparency, good impact resistance, light weight, low price, environmental protection and non-toxicity. It is a widely used glass substitute. The biggest feature of PMMM is its excellent optical properties, which is also the origin of its common name "plexiglass". Mainly because it is an amorphous polymer with uniform texture, its internal molecular arrangement will not affect the speed of light entering the interior through each part, and the pipeline can move forward at the same speed without being scattered in all directions and interfering with each other.
