Applications

Acrylic PMMA resin is used in applications requiring excellent optical, light transmittance an weatherability. It is often used in optical applications, lighting applications, as well as surface finish & scratch finish-resistant applications.

Some specific applications for Acrylic PMMA resin include:

  • Lenses
  • Mobile Phone Lenses
  • Rear Projection
  • Touch Screens
  • Light Fittings
  • Interior & Exterior Automotive Lighting
  • Exterior Appliance Housings
  • Illuminated Signage
  • Street Lighting
  • Industrial Lamps
Advantages Acrylic PMMA resin serves as an economical alternative to polycarbonate when extreme strength is not required.

It offers a high refractive index and outstanding light transmissibility. In fact, white light transmittance can be as high as 95%.

Acrylic PMMA also demonstrates the greatest surface hardness of any plastic. It also provides excellent clarity, surface finish, dimensional stability, weatherability and high impact strength.

Disadvantages

The disadvantages of Acrylic PMMA include:

  • Low Water Absorption
  • Some Notch Sensitivity
