Acrylic plastic, also known by many names like PMMA (Polymethyl methacrylate), 

Plexiglass, Plexiglas, etc., is a transparent thermoplastic material known by its chemical name “plexiglass,” 

 with excellent strength, rigidity, and optical clarity. The material has many similarities with Polycarbonate and, 

due to its high impact resistance, is also heavily utilized as a replacement for glass.


One key difference between acrylic and polycarbonate is that the former doesn’t contain the potentially harmful 

substance bisphenol-A (BPA), and the latter has greater impact strength. The Density of acrylic is lower than polycarbonate.


The one feature differentiating acrylic from other transparent plastics is its excellent weathering properties. 

Acrylic plastic sheets are easy to process and blend with most organic solvents and adhesives.


The supreme optical properties make it one of the clearest plastic on the market. 

In addition, good transparency makes it suitable for various applications.


The melting point of acrylic is 320 °F (160 °C).


Today, most acrylic plastic is sold in sheets of varying thickness depending on the applications, 

but it can also be found in the form of rods or tubes. 

In addition, the stylized frosted, non-glare, and mirrored versions are also making the rounds in the market.
