What is Plexiglass?

The scientific name is polymethyl methacrylate (PMMA) for the transparent plastic. Plexiglass has comparable transparency to traditional glass. However, the plastic material is significantly light and durable enough to become a worthy substitute.

Over time, plexiglass has become directly synonymous with acrylic. It’s like Kleenex for tissues or Band-Aid for adhesive bandages. Such a mis-concepted interchange highlights its widespread adoption.

The term ‘Plexiglass’ is a prominent brand name. It’s more of a generalized term for PMMA. Some other synonymous brand names include Acrylite, Lucite, and Perspex. Those names represent similar acrylic sheets that feature identical attributes.

Chemically, plexiglass is a synthetic polymer derived from methyl methacrylate (MMA). MMA is the monomer that undergoes polymerization. Polymerized MMA eventually creates pure PMMA.

Its molecular structure has long chains of carbon atoms bonded to methyl and ester groups, combining rigidity and flexibility. Unlike glass, plexiglass doesn’t splinter on impact. Instead, it may crack in a controlled manner to reduce injury risks.

History and Development of the Shatter Resistant Alternative

German chemist Dr. Otto Röhm invented PMMA plexiglass back in 1933. Röhm, with his business partner Otto Haas, founded the Röhm and Haas company in 1907. Röhm launched the successfully synthesized PMMA under the brand name ‘Plexiglas.’

The original term was later anglicized to ‘Plexiglass.’ It marked a significant milestone in metallurgic science, especially in innovative plastics. A timeline of plexiglass adoption in typical applications –

• 1930s: Plexiglass gained initial recognition for its optical clarity and durability. Aircraft canopies and submarine periscopes utilized the material during World War II.
• 1940s – 1950s: Post-war, Plexiglass found applications in many industries. It became popular for illuminated signage, architectural designs, and household items.
• 1960s – 1970s: The usability expanded further with uses in automotive, greenhouse, and furniture. Its resistance to UV radiation made it ideal for outdoor applications.
• 1980s – Present: Continued evolution has made it to modern sectors (LED, medical, and renewable energy). Its recyclability, and environmental resistance gained momentum.

Ongoing research and development efforts emphasize the enhancement of plexiglass properties. Modern, advanced applications present more complexity, and improvements are being made to meet the demands.
