3mm Red Coloured Acrylic 431

A safer, lighter, and more durable alternative to glass, this red 3mm coloured acrylic sheet delivers comparable optical quality with significantly better impact resistance and workability.

Manufactured as a cast acrylic, this red sheet offers superior optical qualities and machining characteristics compared to extruded alternatives. The colour runs through the full 3mm thickness — meaning laser-cut edges, drilled holes, and routed profiles all maintain the same consistent red tone. UV-resistant properties protect against discolouration from prolonged sun exposure.

Equally at home in restaurant and bar interiors, entertainment venues, and themed commercial environments, the 3mm thickness provides sufficient rigidity for freestanding signs, wall-mounted panels, and structural glazing while remaining practical to handle and install. Compatible with laser cutting, CNC routing, and thermoforming. Available cut to size for bespoke project requirements.

Optical & Aesthetic

• Colour consistency: The red pigment runs through the full 3mm thickness — cut edges display the same colour as the surface.
• Surface finish: High-gloss polish on both faces for a professional appearance without post-processing.
• UV stability: Resistant to yellowing and colour fade from prolonged UV exposure.

Mechanical Properties

• Impact resistance: Up to 17 times more impact-resistant than glass. Fractures into dull-edged pieces rather than dangerous shards.
• Weight: Approximately half the weight of equivalent glass — easier to transport, handle, and install.
• Weather resistance: Performs well outdoors without warping, cracking, or degrading.

Workability

• Machinable: Can be cut, drilled, routed, and polished. Compatible with laser cutting and CNC routing.
• Thermoformable: Can be heated and bent for curved components using a strip heater or oven.
• Bondable: Joins cleanly with solvent-based acrylic adhesives (Tensol, Extru-Fix).

Specification

• Material: Cast acrylic (PMMA)
• Thickness: 3mm
• Fire rating: Self-extinguishing, classified to BS 476
• Water absorption: Less than 0.3% — suitable for wet environments and outdoor installations

Signage & Visual Impact

• The bold red colour makes this 3mm sheet a strong choice for wayfinding signage, directional boards, and information panels. 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 kitchen splashbacks, bathroom panels, and decorative wall features.
• 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 motorcycle windscreens, boat windows, and vehicle glazing. 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.
