PolyMethylMethacrylate. Thermoplastic acrylic resin obtained by polymerization of methyl methacrylate.
Features and applications of prime PMMA
 PMMA is transparent, hard, rigid, relatively brittle but extremely abrasion resistant, stable when exposed to UV light, but easily flammable. It can be produced in many shades of hazy or opaque colours and it is widely used in place of glass as a shock-resistant solution (Plexiglas). The polymerization of  the monomer is used in moulding for casting products and components of great size (portholes, advertising lighted signs) or to produce very thick sheets and articles. Thanks to  the versality of its polymerization, PMMA is also used in suspensions or solutions for paints, inks, adhesives, textile finishing, leather, paper and, having no smell nor flavour, is widely used in the food industry (pipes for cheese and wine industries). Beyond these specific applications, this material is mainly used for the production of transparent sheets, infrangible glasses, advertising light panels, bathrooms and its accessories, furniture, decorative and technical items, toys, electrical and electronic appliances, medical products (especially in dentistry).
