Products Description of Methyl methacrylate CAS# 80-62-6
Polymethacrylate, whose full name is polymethyl methacrylate (PMmaleic-anhydride.html">MA), is an important optically transparent plastic. It features high transparency, strong impact resistance, light weight, low cost, eco-friendliness and non-toxicity. It serves as a widely applied glass replacement material. The most prominent characteristic of PMMA is its exceptional optical performance, which gives it the common name “plexiglass”. As an amorphous polymer with uniform structure, its internal molecular arrangement does not disturb the speed of light passing through different parts. Light can travel forward at a consistent speed without scattering or mutual interference.

Product Applications
Methyl methacrylate is primarily used as the key monomer for organic glass (PMMA) and is also utilized in manufacturing other plastics and coatings.
Polymethyl methacrylate (PMMA), a widely used optically transparent polymer, boasts high light transmittance, strong impact resistance, light weight, low cost, environmental friendliness and non-toxicity, serving as a popular glass substitute. Its outstanding optical performance earns it the common name “plexiglass”; as an amorphous polymer with a uniform structure, its molecular arrangement enables light to pass through at a consistent speed without scattering or interference.
