The government has banned the import of polymethyl methacrylate (PMAA), with effect from September 1, commerce and industry ministry said in a notification. Polymethyl methacrylate is a shatterproof replacement for glass. Import policy of polymethyl methacrylate is revised from free to prohibited with effect from September 1 this year. As per the existing import policy, imports of the product were free. India imported Rs 8.43 lakh worth of the product in the first quarter of 2019-20 compared with Rs 45.74 lakh in 2018-19. 
  1. Poly(methyl methacrylate) (PMMA), also known as acrylic, acrylic glass, or plexiglass as well as by the trade names Crylux, Plexiglas, Acrylite, Lucite, and Perspex among several others, is a transparent thermoplastic often used in sheet form as a lightweight or shatter-resistant alternative to glass. 
  2. The same material can be used as a casting resin, in inks and coatings, and has many other uses.
  3. Although not a type of familiar silica-based glass, the substance, like many thermoplastics, is often technically classified as a type of glass (in that it is a non-crystalline vitreous substance) hence its occasional historical designation as acrylic glass. 
  4. Chemically, it is the synthetic polymer of methyl methacrylate. The material was developed in 1928 in several different laboratories by many chemists.
