Acrylic

The good atmospheric stability and clarity of these resins have made their use as high impact window panes and other "see-through" barriers important in industry. Acrylic is widely used in the display industry for numerous applications.  Various modifications are being made to alter the properties of the basic acrylic resins for specific services. However, these are not found in any great use in the industrial area to date. Upper temperature of usefulness is approximately 90 °C. The loss in light transmission is only 1% after five years exposure.
