Polycarbonate vs Plexiglass


VS Plexiglass

Plexiglass (or PMMA/Polymethylmethacrylate) is more transparent than glass, polycarbonate and fiberglass, having a transparency coefficient of 0.93. It resists shocks up to 12 Joules (for 4-mm thick), atmospheric agents, humidity and chemical agents. For this reason, it is widely used in the interior design industry.

It is a flexible material that can be thermoformed but is not as shatterproof and elastic as polycarbonate. It is available in different colors and thicknesses (from 1 to 30 mm). However, if it is exposed to the external environment it can present defects: over time and solar radiation, it tends to yellow if not treated with anti-UV additives, to harden and to crack. It also gets easily scratched and therefore requires moderate cleaning.

However, it is a material used for various applications without special technical needs, such as external covers, displays and showcases.

Benefits of plexiglass

  • Transparency
  • Resistance to chemical agents
  • Modeling by thermoforming
  • Colours and thickness customization

Disadvantages of plexiglass compared to polycarbonate

  • Yellowing due to UV rays
  • Poor impact resistance
  • Requires moderate cleaning
  • Reduced elasticity
  • Poor fire resistance
  • High quality/price ratio
