Cast acrylic is the most versatile of sheet materials. Its high transparency and durability make it an excellent choice for applications where appearance is important. A UV stable product, which is perfect for both outside signage and many internal usages such as POS and display features, it is available in a range of coloured finishes.
With a hard, high gloss surface and exceptional mechanical properties combined with a wide range of colours and finishes, cast acrylic sheet offers the user utility as well as decoration. Readily fabricated and formed using conventional tools and equipment, cast acrylic sheets are the ideal thermoplastic sheet material for signage and point of sale and LED designs.
Available in clear, opal, white and black cast acrylic is a perfect choice when a visual impact is required.
Our range of cast acrylic opals, available in all industry standard tints and light transmissions are optimised for back-lit lighting applications whilst also providing a clean, bright appearance during daylight hours when the product is not illuminated.
For more demanding application a cast acrylic for with high-impact strength can be used.
