Methyl methacrylate is a colorless liquid, which is a monomer for the production of transparent plastic polymethylmethacrylate (PMMA). Polymethacrylate is an important optical transparent plastic, which has the advantages of high transparency, good impact resistance, light weight, low price, environmental protection and non-toxic. It is widely used as a substitute for glass. PMMM is characterized by excellent optical properties, which is also the origin of its common name "plexiglass", mainly because it is an amorphous polymer with uniform texture, The arrangement of internal molecules will not affect the speed of light passing through each part. The pipeline can move forward at the same speed, and will not be scattered around and interfere with each other.
