PERSPEX ® Opal acrylic sheet is a premium cast acrylic product engineered for superior light diffusion and visual performance. Featuring a range of opaque to translucent white tones, Opal sheets are designed to refract and diffuse light evenly, creating a soft, uniform glow ideal for illuminated applications. With light transmission options up to around 70%, Opal delivers excellent haze and light scattering for consistent illumination effects across a variety of projects.
Manufactured to the high quality standard expected of genuine PERSPEX®, Opal sheets offer excellent surface hardness, colour consistency, durability, and weather resistance, backed by the PERSPEX® guarantee. They are lightweight yet robust and are easy to cut, router, drill, and fabricate for custom designs. Protective film on both sides ensures surfaces remain pristine during handling and processing.
Typical applications include lightboxes, illuminated signage, diffusers for LED lighting, retail displays, architectural panels, partitions, and creative interior design elements where soft, even light and a clean, high-quality finish are essential.
