| Applications | Acrylic PMMA resin is used in applications requiring excellent optical, light transmittance and 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:
|
| 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:
