PMMA (Polymethylmethacrylate) also known as acrylic or acrylic glass is a transparent thermoplastic material with light transmittance of 92%.
PMMA is produced by means of of radical polymerization (in emulsion, solution and in mass) and is an atactic and completely amorphous polymer.
PMMA is one of the hardest and scratch-resistant thermoplastic polymers. High UV-resistance is also an undeniable advantage of this material. Due to high polarity of the polymer, it is suitable for gluing and reinforcing most of the adhesives and thermosetting resins.
The impact strength of PMMA is higher than that of conventional glass and general purpose polystyrene, but lower than polycarbonate.
