Perspex

Perspex is the original British cast acrylic — the brand that the word "perspex" became shorthand for. Manufactured in the UK since the 1930s, it remains the benchmark cast acrylic for clarity, machining and finish quality, and it's what most laser cutters, sign makers and architectural fabricators specify when they want a known quantity.

Our Perspex collection covers clear, frosted, opaque and coloured sheets, plus their pastel, fluorescent and mineral-effect ranges. Typical sheet thicknesses run 3mm to 5mm with sample sizes available across most lines. Common uses include jewellery components, interior signage, display fittings, mosaic and model-making, retail point-of-sale, and small-furniture inlays.

If you're choosing between Perspex and another cast acrylic, the practical differences come down to colour matching and supply consistency — Perspex's pastel and fluorescent ranges in particular are widely specified in the design trade. For pure optical clarity work or large-sheet projects, also look at our wider cast acrylic sheets collection, which sits alongside the Perspex range.
