Lightweight and strong
Acrylic weighs 50% less than regular glass, and still it is a lot stronger: compared to glass, acrylic is 30 times as impact resistant. It takes a lot of force to break an acrylic sheet, but when is does break it cracks in a clean line and will not splinter like glass. In comparison to glass, acrylic has a higher transparency and lets through more light. This will be especially apparent when comparing thicker acrylic and glass sheets.
Weather resistant
Acrylic’s strength makes it ideal for outdoor applications, such as wind breaks and skylights. For these purposes it also helps that acrylic is UV and weather resistant. Because of the dense surface, water and dirt won’t stick. Regular cleaning with an anti-static plastic cleaner is recommended to prevent the acrylic sheet from attracting dust.
Easy to process
Acrylic is easy to work with, but there is a clear difference between cast and extruded acrylic sheets. Extruded acrylic sheets are less suitable for certain processing because of internal tension in the material. This tension makes extruded sheets prone to breaking when you drill or saw them. This is a cast sheet, so with the right tools and preparation it is easy to work with. The sheet is covered by a protective film to protect it from damage during transport and handling.
Characteristics
Cast acrylic sheets have a few important characteristics. The following aspects are good to know about our acrylic sheets:
Workability
Cast acrylic is better suited for processing than extruded acrylic. Extruded sheets contain more internal tension due to the production method, therefore they are more likely to break. This is a cast sheet, so with the right tools it is easy to work with.
Applications
The acrylic sheet is UV resistant, therefore it is an excellent choice for indoor and outdoor applications. Often, acrylic is used as a replacement for glass because it is lightweight, strong and has a high transparency.
