Plexiglass versus Acrylic

Readers have uproar as they find it hard to reconcile the relationship between plexiglass and acrylic. I can testify to this because I got confused when going through online resources only to discover that acrylic and plexiglass were interchangeable.

For example, if you are reading up on the best way to cut plexiglass, and the resource pointed out a list of acrylic sheet cutters, you’ll get confused, right?

The question is, does a difference between acrylic and plexiglass exist? The truth is, there is no difference. Now let’s have a look at what binds them together.

Acrylic is polymethyl methacrylate, often used as an alternative to glass. Although glass is cheaper, acrylic leads the race due to its unique feature sure as shatter resistance(occurring as plastic), weight, flexibility, and less reflectivity.

Plexiglass is a brand name for acrylic. It is a tale of a brand that started small and growing to become acrylic’s trademark name.

The application of plexiglass sheets includes furniture, windows, bathtubs; the list goes on and on.

We can see that there is no difference between plexiglass and acrylic.
