'''폴리메타크릴산 메틸'''(Poly(methyl methacrylate), PMMA)은 [[엔지니어링 플라스틱]]이라 불리는 물질들을 한데 묶어 부르는 말이다. [[투명]]한 [[열가소성 플라스틱]]이다. PMMA는 Crylux, Plexiglas, Acrylite, Astariglas, Lucite, Perclax, Perspex 등 여러 상표명과 브랜드로도 알려져 있다.

폴리메타크릴산 메틸은 [[극한 인장 강도]], [[굽힘 강도]], [[투명]]도, 광택성, UV 저항도가 충격 강도, 화학 저장성, 열 저항성보다 더 중요한 경우 [[폴리카보네이트]](PC)의 경제적 대안으로 사용할 수 있다.<ref>{{웹 인용|url=https://www.hydrosight.com/acrylic-vs-polycarbonate-a-quantitative-and-qualitative-comparison/ |title=Acrylic vs. Polycarbonate: A quantitative and qualitative comparison |author=Hydrosight |url-status=live |archive-url=https://web.archive.org/web/20170119194950/http://www.hydrosight.com/acrylic-vs-polycarbonate-a-quantitative-and-qualitative-comparison/ |archive-date=2017-01-19}}</ref> 게다가 폴리카보네이트에서 발견되는 잠재적으로 유해한 [[비스페놀 A]]를 함유하고 있지 않으므로 레이저 절단에 훨씬 더 나은 선택이기도 하다.<ref>{{웹 인용|url=https://cpl.org/wp-content/uploads/NEVER-CUT-THESE-MATERIALS.pdf |title=Never cut these materials}}</ref>
