Acrylic Sheets (PMMA sheets)
Polymethyl methacrylate (PMMA) is a transparent thermoplastic. Its superior light transmission properties, rigidity and scratch resistance renders it to be used as a better alternative to glass in most areas of applications. Since it is lighter than glass, structural requirements are lesser compared to glass. It is sometimes called acrylic glass. Acrylic is a synthetic polymer of methyl methacrylate.

Features of Acrylic sheets
- Impact strength: The impact strength of Acrylic sheets is 17 times that of glass
- Light weight: The weight of an Acrylic sheet is only about half of glass
- Transparency: The light transmission of Acrylic sheet is 93%(clear) Glass is only 90%
- Scratch resistance
- Good chemical resistance, superior to most other plastic materials Chlorinated water has little or no effect on acrylic where as mineral glass degrades rapidly
- Thermo formable
- Free of any kind of heavy metal or poisonous ingredient
- Can be milled, polished, routed, cut, bonded, screwed etc
- Can be easily cold and hot bended, decorated with lamination and printing
- Resistance to weather: Acrylic sheet has good resistance to bad weather and is not prone to yellowing
