Government bans import of PMAA
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.
- 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.
- The same material can be used as a casting resin, in inks and coatings, and has many other uses.
- 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.
- Chemically, it is the synthetic polymer of methyl methacrylate. The material was developed in 1928 in several different laboratories by many chemists.
