  2. PMMA transmittiert sichtbares Licht besser als Mineralglas. Bei einer Dicke von 3 mm lässt PMMA bis zu 92 % des sichtbaren Lichts durch und reflektiert etwa 4 % von jeder seiner Oberflächen aufgrund seines Brechungsindex (1,4905 bei 589,3 nm)
  3. Le PMMA ne peut pas être utilisé comme écran de protection de machines industrielles, il est nécessaire d'utiliser du polycarbonate qui ne présente pas de danger lorsqu'il se brise. Recyclage. Le PMMA peut être fondu puis remoulé, mais c'est surtout par dépolymérisation qu'il peut être recyclé facilement. Par chauffage, le PMMA.

Like PMA, it is known for producing extremely dangerous, life-threatening side effects. At lower dosages, its effects are somewhat different from PMA, with reduced tendency to cause severe.

PMMA wordt minder gebruikt voor veiligheidstoepassingen, het is minder impactbestendig (wel beter dan glas) en het breekt in scherpe stukken. Tegenwoordig zijn er wel PMMA kwaliteiten die behoorlijk impactbestendig zijn. Bovendien is het zeer brandbaar dus kan het nooit gebruikt worden bij personentransport (treinen, trams, bussen) História. O PMMA foi descoberto no início de 1930 pelos químicos britânicos Rowland Hill e John Crawford e teve por sua primeira aplicação pelo químico alemão Otto Rohm em 1934 [3].A primeira grande aplicação do PMMA ocorreu durante a Segunda Guerra Mundial, quando ele foi usado em janelas, cúpulas de aeronaves e periscópios de submarinos [3] Poly(methyl methacrylate) (PMMA), cũng có các tên gọi khác như thủy tinh hữu cơ, nhựa acrylic hoặc thủy tinh acrylic.
