Product Introduction
White PVC Celuka Foam Board - Dense Skin, 1 to 30 mm
A rigid sheet with a dense, smooth skin on both faces over a lighter closed-cell core.
White Celuka foam board is a rigid PVC sheet with a dense, smooth skin on both faces over a lighter closed-cell core. The skin is the point of the product. It gives the sheet a surface that prints cleanly, machines to a crisp edge and holds screws far better than a foamed surface would, while the core keeps the sheet light.
This page sets out the range, what the density grades mean in practice, and how the sheet is specified for printing, fabrication and cabinetry. The underlying technical choices - density, thickness and skin - are covered in the linked guides rather than repeated here.

The Range
Two variables are chosen separately, and they answer different questions. Thickness sets the stiffness of the sheet and how much it will deflect over a span. Density sets the hardness of the skin, the screw holding and how the sheet machines. A thin, dense sheet and a thick, light one are different products for different jobs.
| Thickness, mm | Typical use |
|---|---|
| 1 to 3 | Model making, thin display panels, roll-forming for displays, thin backing and faces. |
| 4 to 6 | Signage, display boards, printing substrate, point-of-sale panels, light fabrication. |
| 8 to 12 | Structural signage, routed lettering and logos, cabinet backs and panels, exhibition stands. |
| 15 to 20 | Cabinet carcass panels, furniture, partitions, wet-area lining, machine-cut parts. |
| 25 to 30 | Heavy routed parts, jigs and fixtures, engineered panels where a solid-like section is needed. |
Density is the second variable, and it is the one that governs surface behaviour. The table below describes what each grade is normally used for; exact values are confirmed against the specification.
| Density, g/cm³ | What it changes | Typical use |
|---|---|---|
| 0.45 to 0.5 | The lightest and softest surface, with the lowest screw holding. | Short-life display, model work, light signage where the sheet is mostly printed and not loaded. |
| 0.55 to 0.6 | A harder skin that prints and machines well, with useful screw holding. | General signage and display, retail fixtures, printing substrate. |
| 0.65 to 0.7 | A harder skin again, with better edge strength for routing. | Routed parts, cabinetry, furniture, panels that carry fixings. |
| 0.8 | The hardest surface in the range, and the heaviest. | Demanding screw holding, heavy machining, parts that will be handled repeatedly. |
Thickness buys stiffness, density buys hardness - they are not the same lever
A common specification error is to assume a thicker sheet will also hold screws better or machine more cleanly. It will not. Stiffness rises sharply with thickness, while screw holding and surface hardness rise with density, and specifying one high without the other does not substitute. The reasoning is set out in our guides to density grades and applications.
Thickness and density are separate decisions, and they answer separate questions about the finished sheet.
The full specification for each grade, including sheet size, surface finish and tolerance, is issued with the quotation. Where a project sits outside the standard ladder, the range can be extended against a minimum quantity - see sourcing below.
What Is in the Sheet
A Celuka sheet is not a uniform slab. It is a sandwich, with a dense skin on each face over a closed-cell core, and the skin is doing most of the work you are paying for.
The skin
A solid, smooth PVC layer on both faces. It is the surface that receives ink, the edge that machines cleanly and the material a screw actually grips. Its hardness and thickness are what set printing quality, edge definition and screw holding.
The core
A lighter closed-cell foam. It contributes most of the thickness while contributing less of the weight, and because it sits in the middle of the sheet it does not see the surface loads the skin does.
The name Celuka is used more loosely than it should be
Celuka refers to a process that produces a dense skin over a foamed core. Not every board sold under the name has the same skin, because the name is sometimes applied to free-foam board, which has a foamed, porous surface and a lower price. The practical check is the surface: a Celuka sheet has a hard skin you can feel, and a free-foam board is visibly porous to the touch and will not print or hold screws the same way. Where a project depends on surface quality, the skin is the thing to verify rather than the name.
The comparison between this product and a free-foam board of the same nominal density is set out in our guide to Celuka versus free-foam board. The short version is that the two are not interchangeable, and the difference is concentrated in the surface.
Surface and Printing
The dense skin is what makes this sheet a printing substrate rather than simply a board. The surface is closed and consistent, which means ink sits on it cleanly and a cut edge exposes a near-solid face rather than an open cell structure.
The surface accepts UV flatbed and screen printing directly, and takes self-adhesive film and vinyl cleanly. It also bonds well, so it can be laminated or face-mounted. The finish is normally a smooth matte, with a semi-matte available on some grades.
White is not one white
Sheets carry a warm or a cool undertone depending on the pigment system, and the difference is invisible on a single sheet and obvious when two sheets sit edge to edge. Where panels are being joined into a larger surface, the tone should be specified or a single production batch used, because a warm white and a cool white will show a visible seam. The discipline of specifying and measuring colour is set out in our guide to colour and batch consistency.
A closed skin is the difference between a board that takes ink cleanly and one that soaks it into an open surface.
The comparison with the other substrates used in the same roles, and which of them suits which job, is set out in our guide to foam board versus acrylic, ACM and corrugated plastic.
Machining and Fabrication
The sheet machines with ordinary woodworking equipment, and the dense skin is what gives routed edges their definition. It cuts, drills, routes and saws cleanly, and it can be joined with screws, adhesives or solvent bonding.
Three fabrication points are worth stating before they are discovered in the workshop. The first is that screw holding rises with density, so a light sheet will not carry a loaded fixing no matter how carefully it is fitted. The second is that routing produces a clean edge because the skin is solid, and an edge that will be seen is normally finished rather than painted. The third is that the sheet can be heat-formed into gentle curves, and it is not a deep-draw thermoforming material; the range of what it will do is narrower than that of a dedicated forming plastic.
Use the grade that matches the load
A display panel that carries only its own weight works at a light density. A routed part with fixings, or a cabinet panel that has to hold a hinge, needs a denser grade, because the screw is gripping the skin and the core together and a light core gives it little to hold. Our guide to foam board for cabinet making covers the density and fixing decisions for loaded panels.
The full tool and finishing requirements, including what works and what does not, are covered in our guide to tools and finishes for expanded PVC.
Where It Is Used
| Application | Typical grade | What drives the choice |
|---|---|---|
| Signage and display | 4 to 10 mm, 0.5 to 0.6 | A printable skin and enough stiffness for the span between fixings. |
| Routed lettering and logos | 10 to 19 mm, 0.6 to 0.7 | Edge definition and the ability to hold detail in a routed edge. |
| Cabinetry and furniture | 15 to 20 mm, 0.65 to 0.7 | Screw holding at the edges, and stiffness across the carcass. |
| Exhibition and retail fixtures | 8 to 12 mm, 0.55 to 0.6 | Weight, because the structure has to move, and a clean printed surface. |
| Model and display work | 1 to 5 mm, 0.45 to 0.5 | Workability and weight, with mechanical properties mostly irrelevant. |
One application deserves a note rather than a table row. White board is used outdoors for signage, and it should be treated as a product with a limited exterior life. Prolonged exposure yellows the surface over time, and the rate depends on the exposure and the pigment system rather than on the density. Where a sign has to look the same for years, the exterior durability question should be part of the specification rather than assumed. The mechanism is set out in our guide to how UV, heat and moisture age a PVC surface.
Sourcing and Customisation
We supply white Celuka board to importers, distributors, converters and own-brand programmes. Four things are normally agreed before an order is confirmed.
The specification as values rather than a description - thickness, density, sheet size and surface finish.
The application, so the grade is matched to the load rather than to a habit.
The quantity, the packing and the shipping terms, quoted against the specification.
The document set required for the destination market, confirmed before production.
Minimum quantity depends on what is being changed
Ordering a standard white sheet in a standard size carries one minimum. Changing the thickness, the density, the colour or the sheet size involves setup and carries another. Because the figure moves with the specification, we quote it against the actual requirement rather than publishing a number that would be wrong for most enquiries. Sending the specification first is the fastest route to a usable quotation.
White is the standard colour. Other colours and laminated surfaces are available against a minimum quantity.
Beyond standard white, the sheet is available in colours, and with laminated or coated surfaces for specific finishes. Custom sheet sizes and thicknesses can be produced against a minimum quantity. The process for developing a custom specification, and what the request needs to contain, is set out in our guide to custom foam board production.
Frequently Asked Questions
Buying White Celuka Foam Board
Questions we are asked most often at the enquiry stage.
What is the difference between Celuka and free-foam board?
Celuka has a dense, smooth skin on both faces over a foamed core. Free-foam board is foamed all the way through, so its surface is porous. The skin is what gives Celuka its printing quality, edge definition and screw holding, and it is the reason the two products are not interchangeable despite similar densities.
What density should I choose?
Match it to what the sheet has to carry and how it will be worked. A display panel that only holds its own weight works at a light grade. A routed part with fixings, or a cabinet panel that holds a hinge, needs a denser grade for screw holding and edge strength. If you tell us the application, we will confirm the grade rather than leaving it to a guess.
Can it be printed on directly?
Yes. The closed skin takes UV flatbed and screen printing directly, and accepts self-adhesive film and vinyl cleanly. This is the main reason the product is used as a printing substrate, and it is the property that separates it from a free-foam board, which would soak ink into an open surface.
Can it be CNC routed?
Yes, with ordinary woodworking tooling. The dense skin is what gives routed edges their definition, so the result improves with the density grade. An edge that will be seen is normally finished rather than painted, and a loaded fixing should be placed in a sheet dense enough to hold it.
Is the white consistent between batches?
White carries a warm or a cool undertone depending on the pigment system, and the difference shows when two sheets sit edge to edge. Where panels are being joined, the tone should be specified or a single batch used. The subject of batch consistency, and how to specify colour so it can be checked, is covered in our guide to colour and batch consistency.
Can it be used outdoors?
Yes, and it should be treated as having a limited exterior life. Prolonged exposure yellows the surface over time, and the rate depends on the exposure and the pigment system rather than on density. Where a sign has to look the same for years, exterior durability should be part of the specification rather than assumed.
What sheet sizes are available?
1220 by 2440 millimetres is the standard, with larger sheets available on some grades. Custom sizes can be produced against a minimum quantity. Exact available sizes are confirmed with the quotation, since they vary with the thickness and density.
Can I get colours or laminated surfaces?
Yes. Beyond standard white, the sheet is available in colours, and with laminated or coated surfaces for specific finishes. Custom colours and surfaces carry a minimum quantity and are developed from a physical sample or a measured colour reference. The process is set out in our guide to custom foam board production.
