Is plexiglass a glass or plastic?

Although chemist and inventor Otto Rohm had first come up with the idea for plexiglass in 1901, it wasn’t until 1933 that the Rohm & Haas company first introduced it to the market under the trademark name Plexiglas. The material, which is considered a lightweight and shatter-resistant alternative to glass, has had a fascinating history and experienced a multitude of different uses in that time. Today, plexiglass continues to be utilized in new and interesting ways, including as a potential means with which to help combat coronavirus spread. Restaurants, stores, and other businesses have begun using plexiglass partitions as protective shields for both workers and customers, especially as cities and towns slowly reopen. Below, we dive into this unusual material, addressing its material properties, its history, and the ways it continues to be used today.
