precision laser cut acrylic PMMA samples

Poly(methyl methacrylate) PMMA

The laser cutting material Acrylic is a transparent plastic material exhibiting excellent optical clarity, strength and stiffness. These properties, combined with superior weathering qualities makes it versatile for many applications. Other names include Plexiglass and trade names; Perspex, Plexiglas & Acrylite.


Many applications most commonly as an alternative to glass.


• Excellent clarity
• Lightweight
• Good impact resistance
• Outstanding thermal insulator
• UV resistant
• Easy to heat-form
