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.
• Good impact resistance.
• Outstanding thermal insulator.
• UV resistant.
• Easy to heat-form.
