PMMA (Acrylic)

Polymethyl methacrylate (PMMA), also known as acrylic or acrylic glass, is a transparent and rigid thermoplastic. Because of its properties, like transparency, easy maintenance, low cost, lightweight and shatter-resistance, it is often used as a substitute for glass and is preferred for many applications.

  • High Transmittance:Highest luminous transmittance of all the transparent plastics. PMMA allows 92% of light to pass through it.
  • Surface Hardness:Its surface hardness is close to aluminum, and it is the highest in all transparent plastics. It has excellent scratch resistance comparing to other transparent polymers.
  • Good Weather Resistance:Excellent weather resistance with little change in transparency and color in the tropical climate for many years.
  • Excellent Chemical Resistance:Unaffected by dilute inorganic acids, alkaline, non-polar, aliphatic hydrocarbons, and greases, etc.
  • Excellent Hydrolysis Resistance
