FIDAR System's white PVC sheets are a closed-cell rigid PVC product - lightweight, moisture-resistant, and easy to cut, route, and score. The smooth white surface is print-ready and accepts most adhesive films and vinyl wraps without priming.

Properties

  • Closed-cell structure - does not absorb moisture
  • Lightweight: approximately 0.55 g/cm³ (less than half the weight of acrylic)
  • Smooth white surface on both sides
  • Excellent for CNC routing, sawing, and scoring (never laser cut: PVC gives off hydrogen chloride gas)
  • Print-ready - accepts solvent, UV, and latex inks

Applications

  • Flat-cut sign blanks and substrates
  • Foam board display mounting
  • Architectural model-making
  • Exhibition and trade show panels
  • Point-of-sale and retail display structures
  • Bathroom and wet-area panelling

Fabrication Notes

PVC cuts easily with a sharp utility knife, circular saw, or CNC router. Do not laser cut it: PVC gives off hydrogen chloride gas under a laser, which is hazardous to breathe and corrodes the machine. For clean edges, use a carbide-tipped blade or O-flute router bit. PVC bonds well with contact cements and most acrylic adhesives.

Signage & Graphics

Flat-Cut Sign Panels & Substrates

White PVC is the most common substrate for flat-cut sign panels in Canada. Sign shops use 6mm and 10mm sheets for vinyl-applied directional signs, flat-panel corporate signs, and indoor signage systems. The smooth white surface accepts vinyl films, digital prints, and painted finishes without priming.

Events & Exhibitions

Exhibition & Trade Show Panels

Trade show display builders use white PVC for panel walls, curved display structures, and branded exhibition components. The lightweight nature (~0.55 g/cm³) reduces shipping weight and allows large-format panels to be handled and installed without heavy equipment.

Architecture & Design

Architectural Model Making

Architectural and interior design studios use white PVC foam board for scale models and concept models. The material cuts cleanly with a utility knife or router, and the white surface provides the clean appearance required for architectural presentations.

Construction & Renovation

Bathroom & Wet-Area Panelling

White PVC's closed-cell structure makes it moisture-resistant and suitable for wet-area applications like bathroom wall panels, shower surrounds, and splash backs where wood-based products would fail over time.

Retail & Printing

Foam Board Replacement

White PVC is a rigid, durable alternative to foam board for mounting prints, photos, and graphics in retail display, point-of-purchase, and indoor advertising applications - without the risk of warping or delamination over time.

How to Fabricate PVC White Sheets

1

Measure & Mark

Mark cut lines directly on the protective film with a marker. PVC has a consistent white surface - a pencil or fine marker shows clearly. For large-format cuts, snap a chalk line or use a straight edge clamped to the sheet.

2

Score & Snap or Saw

For sheets up to 6mm, score multiple passes with a sharp knife along a metal straight edge and snap cleanly. For 10mm-24mm, use a circular saw with a fine-tooth or carbide-tipped blade, or a CNC router with an O-flute upcut bit. Keep feed rates high to prevent melting at the cut edge.

3

Route or CNC-Cut

CNC routing is the preferred method for complex shapes. Use a single-flute O-flute upcut bit - this evacuates chips efficiently and prevents material buildup at the cutter. PVC routing produces smooth, clean edges that rarely need sanding.

4

Clean & Prepare Surface

Wipe the surface with isopropyl alcohol before applying vinyl films, adhesives, or accepting direct print. PVC is chemically compatible with most sign-grade pressure-sensitive vinyls and requires no primer for most applications.

5

Bond or Fasten

Bond pieces with contact cement (apply to both surfaces, allow to tack, press firmly) or a two-part epoxy for structural assemblies. For mechanical fastening, use screws or bolts with wide washers - PVC's lower density means screw pull-out strength is lower than solid materials.

PVC foam board (closed-cell rigid PVC) is lighter (~0.55 g/cm³ vs. 1.19 g/cm³ for acrylic) and less expensive, making it the standard choice for flat-cut sign panels, exhibition displays, and vinyl-applied substrates. Acrylic is harder, more optically attractive, and produces better laser engraving results - making it the choice for display cases, awards, and applications where surface quality and appearance matter more than weight or cost.

White PVC has moderate outdoor weathering resistance. For short-to-medium term outdoor signage (1-3 years), standard white PVC performs adequately. For extended outdoor exposure, UV-protective laminate or UV-stabilized ink systems are recommended to prevent yellowing and surface degradation.

No. PVC is a chlorinated plastic, and a laser turns it into hydrogen chloride gas, which is hazardous to breathe and corrodes the laser's optics and frame. MIT's environment, health and safety office warns that PVC produces hydrogen chloride gas, which it calls extremely dangerous. We never laser PVC, and our cut-to-size tool does not offer it. Score and snap thin sheets with a knife, and saw or CNC route the rest. For laser-cut parts, use cast acrylic.

FIDAR System stocks white closed-cell PVC in six thicknesses: 3mm, 6mm, 10mm, 12mm, 18mm, and 24mm on 4×8 ft sheets, priced from $28.13 to $186.53 CAD per sheet.

Yes. White closed-cell PVC has a smooth, consistent surface that accepts solvent-based, UV-cured, and latex wide-format inks directly without priming. It is a standard substrate for wide-format digital print applications in the signage and display industry.
