FIDAR System stocks white cast acrylic sheets across six colour codes to cover the full range of B2B fabrication needs — from fully opaque bright white to semi-translucent diffused whites ideal for LED backlighting.
White cast acrylic machines cleanly with standard woodworking and plastics tooling. For laser engraving, white acrylic produces a frosted-to-clear result at the engraved area, creating good contrast for logos and text. For LED applications, select the thickness based on the light-to-panel distance — thicker sheets provide more diffusion.
White acrylic (codes 7508 and 7508M) is the standard face material for LED-backlit cabinet signs and light boxes. The semi-translucent properties allow even light distribution through the panel while providing a clean white face when the sign is unlit. 2.8mm and 4.3mm are the most common thicknesses for sign cabinet faces.
High-gloss white acrylic (code 2447 or 402) is a staple material for retail product display risers, pedestals, and shelving inserts. The crisp white surface makes products stand out and photographs well for e-commerce and in-store displays.
White acrylic is commonly used as a backer or face for menu boards in quick-service restaurants, coffee shops, and food court kiosks - particularly 2.8mm and 4.3mm sheets for wall-mounted and counter-top displays.
Thicker white acrylic sheets (9mm–18mm) are used as cladding panels on interior partition walls, reception desk fascias, and feature wall applications. The matte finish codes (2447M, 7508M) are preferred in architectural interiors to reduce glare under ambient lighting.
White cast acrylic laser-engraves to a clear, frosted result - creating a high-contrast engraved area. Commonly used for office door nameplates, desk signs, and corporate plaques where a clean, professional appearance is required.
How to Fabricate White Acrylic Sheets
Choose Your Code
Select the white acrylic code that fits your application: 2447 or 402 for opaque sign faces and display work; 7508 or 7508M for LED light boxes; 2447M or 7508M for matte-finish architectural panels. The M suffix indicates a satin-matte surface.
Score & Snap or Saw
For sheets up to 5.5mm, score deeply along a straight edge with a sharp acrylic scoring knife and snap cleanly. For thicker sheets (9mm–18mm), use a table saw or circular saw with a fine-tooth blade (80T+) for straight cuts, or a band saw for curves.
Router & Edge-Finish
Route profiles and chamfers with a CNC router or trim router using a single-flute spiral upcut acrylic bit. After cutting, flame-polish edges with a propane torch for a clear, polished result - or wet-sand with 400-grit, then 800-grit, then buff for the same effect.
Drill (if required)
Use a slow-speed drill with acrylic drill bits (ground to 60° point angle) to prevent cracking. For mounting holes, use a slightly larger hole than the fastener to allow for thermal expansion.
Bond
For transparent joints, use a water-thin acrylic solvent cement (Weld-On 4) applied via needle applicator to capillary-bond pre-fitted pieces. For structural bonds, use a methylene chloride-based adhesive or two-part acrylic adhesive (Weld-On 40). White acrylic solvent-bonds cleanly - joints are nearly invisible at the bond line.
Thickness Selection Guide
| Thickness | Best For |
|---|---|
| 2.8mm (~1/8") | LED sign faces, thin display panels, backlit menu boards, decorative cabinet inserts |
| 4.3mm (~3/16") | Illuminated channel letter faces, retail display risers, medium-duty sign panels |
| 5.5mm (~1/4") | Larger sign faces, counter displays, display case panels |
| 9mm (~3/8") | Thick display structures, partition panels, heavy-duty enclosure faces |
| 12mm (~1/2") | Structural display components, thick decorative panels, freestanding signage |
| 18mm (~3/4") | High-relief CNC routing, thick decorative bases and pedestals |
Codes 2447 and 402 are fully opaque whites; code 7508 is semi-translucent - it allows light to pass through, making it the correct choice for LED backlit applications. Code 2447 is the industry-standard opaque white with a neutral tone for general signage and display. Code 402 is a fully opaque bright white for painted surfaces and high-contrast display work. Code 7508 is a cool, bright semi-translucent white for LED light box faces and backlit signs. The M suffix (2447M, 7508M) indicates a matte/satin surface finish on the same base colour.
For LED-backlit light boxes and sign faces, codes 7508 and 7508M are the most commonly used. The cooler white tone and light transmission properties of these codes work well with white LED light sources. The 7508M (matte) is preferred when a non-reflective face is required to reduce hot spots and surface glare.
Yes. White cast acrylic cuts cleanly with a CO2 laser and produces a polished edge. When laser-engraved, the engraved area becomes clear or translucent, creating a high-contrast result against the opaque white surface - useful for nameplates, door signs, and decorative engraving.
FIDAR System stocks white acrylic up to 18mm (3/4") in multiple colour codes, on 4×8 ft sheets. The 18mm variant in code 7328 is a recently added size. For applications requiring thicker white acrylic, contact us to check current availability.
White cast acrylic has moderate UV resistance in the sense that its whiteness is less susceptible to yellowing than clear acrylic, because the opaque pigment masks minor UV degradation. However, for long-term outdoor signage exposed to direct Canadian sunlight, we recommend a UV-protective coating or selecting materials specifically rated for outdoor UV exposure.
Cast white acrylic sheets in six colour codes: 402, 2447, 2447M, 7328, 7508, and 7508M. Available in thicknesses from 2.8mm to 18mm on 4×8 ft sheets. Ideal for signage, LED light boxes, displays, and retail fixtures.
