Polymethyl methacrylate (PMMA), also known as acrylic or acrylic glass, is a transparent and rigid thermoplastic material widely used as a shatterproof replacement for glass. PMMA has many technical advantages over other transparent polymer (PC, polystyrene etc.), few of them include:

• High resistance to UV light and weathering,
• Excellent light transmission
• Unlimited coloring options

PMMA or poly (methyl 2‐methylpropenoate) is produced from monomer methyl methacrylate.

PMMA is used in biomaterial applications such as bone cement, lenses, bone substitutes, and drug delivery systems. It is used to remove wrinkles and scars on skin tissue permanently. In dental implants, polymer material PMMA is substituted for missing dental roots. PMMA is also used as a substitute for glass in products such as shatterproof, windows, skylights, illuminated signs and aircraft canopies.
