3mm Blue 751 Coloured Acrylic

This blue 3mm coloured acrylic sheet is manufactured from cast acrylic (PMMA) — a premium-grade thermoplastic valued for its optical clarity, colour consistency, and mechanical strength.

With the blue colour cast through the full 3mm 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.

From marine-inspired retail displays, aquatic features, and creative installations, this blue 3mm sheet adapts to the demands of the application. It machines cleanly on laser cutters, CNC routers, and table saws, and thermoforms at controlled temperatures for curved and shaped components. Available in standard stock sizes or cut to your specification.

Optical & Aesthetic

• Colour consistency: The blue 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
• Density: Approximately 1.19 g/cm³ — significantly lighter than glass (2.5 g/cm³)

Commercial & Architectural

• This blue 3mm sheet is commonly specified for illuminated sign panels, lightbox fascias, and branded environments in corporate, educational, and healthcare environments where colour-coded or branded materials are required.
• Illuminated panels, lightboxes, and backlit displays use coloured acrylic for even light diffusion with vibrant colour saturation.

Interior Design

• For interior applications, it suits feature walls, reception areas, and commercial interior fit-outs.
• 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 art installations, sculptural work, and mixed-media projects.
