5mm Red Coloured Acrylic 431
From £0.21
Red 5mm cast acrylic sheet (PMMA) with high-gloss finish on both faces. Up to 17 times stronger than glass and half the weight. UV-stable colour throughout — suited to bold signage, retail displays, and high-impact interior features (shade 431).
Product description
A popular choice for restaurant and bar interiors, entertainment venues, and themed commercial environments, this red 5mm coloured acrylic sheet combines visual impact with lasting durability.
With the red colour cast through the full 5mm depth of the sheet, every cut edge and fabricated detail maintains a clean, consistent finish. The high-gloss surface on both faces gives a professional appearance straight from the sheet. Resistant to UV degradation, weathering, and moisture, this material holds its colour and clarity in demanding indoor and outdoor environments.
The 5mm sheet is rigid enough for structural panel applications yet light enough for straightforward handling and installation. It can be cut to any shape, drilled, engraved, and thermoformed. Well suited to eye-catching exhibition stands, point-of-sale units, and promotional displays. Bonds with solvent-based acrylic cements for fabricated assemblies. Protective film on both faces.

Usage
Signage & Visual Impact
- The bold red colour makes this 5mm sheet a strong choice for illuminated sign panels, lightbox fascias, and branded environments. High visibility and consistent pigmentation ensure it stands out in busy environments.
- Illuminated panels, lightboxes, and backlit displays use coloured acrylic for even light diffusion with vibrant colour saturation.
Retail & Commercial
- In retail and commercial settings, red acrylic works well for furniture components, shelving inserts, and built-in cabinetry.
- Splashback panels in kitchens and bathrooms provide a hygienic, waterproof surface that is straightforward to maintain.
Glazing & Screening
- A shatterproof, weather-resistant alternative to glass for secondary glazing, greenhouse panels, and skylight installations. Up to 17 times more impact-resistant at approximately half the weight.
Craft & Fabrication
- Compatible with laser cutting, CNC routing, drilling, and thermoforming. Widely used for model making, prototyping, and precision-fabricated components.
