3mm Black Coloured Acrylic
From £0.11
Black 3mm 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 modern signage, contemporary interiors, and sleek furniture panels.
Product description
A popular choice for modern retail environments, corporate offices, and contemporary kitchen installations, this black 3mm coloured acrylic sheet combines visual impact with lasting durability.
Manufactured as a cast acrylic, this black 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 black tone. UV-resistant properties protect against discolouration from prolonged sun exposure.
Beyond visual impact, this black acrylic is practical to work with — it cuts cleanly with standard workshop tools, lasers, and CNC machines, and can be heated and bent into curved shapes for bespoke installations. The 3mm gauge suits professional signage, premium splashbacks, and architectural feature walls. Supplied with protective film and available in custom dimensions.
Properties
Optical & Aesthetic
- Colour consistency: The black 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
- Black 3mm acrylic is well suited to kitchen splashbacks, bathroom panels, and decorative wall features. The black 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 retail signage, exhibition stands, and point-of-sale displays, 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 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 wedding decor, event signage, cake toppers, and table centrepieces.
