3mm Dark Grey Coloured Acrylic 9640
From £0.12
Premium 3mm grey cast acrylic sheet — polished both sides, colour runs through the full sheet depth. Shatterproof, weather-resistant, and compatible with laser cutting, CNC routing, and thermoforming (shade 9640).
Product description
The grey colour offers strong visual presence to any installation. This 3mm coloured acrylic sheet is UV-stable, weather-resistant, and built to perform in both indoor and outdoor environments.
Cast from polymethyl methacrylate (PMMA), the grey pigment is integral to the material rather than applied as a surface coating. This means the 3mm sheet maintains its colour through cutting, routing, and edge polishing. The UV-stabilised formulation resists yellowing and fading, with both surfaces delivered in a polished gloss finish.
Suitable for understated professional environments, commercial offices, and industrial-style interiors. This 3mm sheet can be cut to your exact dimensions, drilled, CNC-routed, laser-cut, and thermoformed for curved components. It bonds cleanly with solvent-based acrylic adhesives and can be polished to restore edge clarity after cutting. Supplied with a protective film on both faces.

Properties
Optical & Aesthetic
- Colour consistency: The grey 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)
Usage
Interior & Exterior Design
- Grey 3mm acrylic is well suited to kitchen splashbacks, bathroom panels, and decorative wall features. The grey tone integrates naturally into modern commercial and residential environments.
- Illuminated panels, lightboxes, and backlit displays use coloured acrylic for even light diffusion with vibrant colour saturation.
Signage & Displays
- For shopfront fascias, window displays, and promotional graphics, the 3mm thickness provides sufficient rigidity for freestanding and wall-mounted installations.
- 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.
