Utilisations

Cabinet Shelves and Bodies

Cabinet shelves and cabinet bodies are the most common application. A 600mm-wide shelf in a kitchen cabinet carries dishes, cookware, and small appliances, typically 20 to 40 kg distributed load. At 15mm Celuka, 0.55 g/cm³, the board provides adequate rigidity for most cabinet shelf applications. At 12mm or at 0.45 density, the same load may produce visible sag. The specification matters because the end user sees the result every time they open the cabinet door.

Retail Display Shelving

Retail display shelving and point-of-sale fixtures use this board where glass would be fragile and MDF would be heavy. A 1.2m-wide display shelf in a retail store benefits from the combination of rigidity (stays flat under product weight), light weight (easier to install and reconfigure than MDF), and a finished surface that requires no painting or edge banding for a clean appearance.

Revêtements muraux et lambris d'intérieur

Wall cladding and interior paneling in commercial spaces, hotel lobbies, restaurant interiors, office partitions, use 8 to 12mm Celuka as a straight, stable substrate that will not warp when the building's humidity changes between seasons. Gypsum board is cheaper but cannot be left exposed as a finished surface. Plywood requires veneering, painting, and edge treatment. By contrast, this board arrives with a finished surface and stays dimensionally stable.

Self-Supporting Signage and Structures

Signage and display structures that must be self-supporting, freestanding exhibition panels, directional signage, architectural wayfinding, use 10 to 18mm board where wind load, accidental bumping, or long-term flatness requirements rule out thin or low-density alternatives.

Specify the Board Construction

Confirm product type. The stiffness comes from Celuka or co-extruded construction. Free foam board, even at high density, will not match Celuka's rigidity at the same thickness because it lacks the structural skin.

Confirm density and thickness together. A 12mm board at 0.70 g/cm³ can approach the stiffness of a 15mm board at 0.50, the two parameters interact. Ask the supplier to provide the flexural modulus for the specific density and thickness combination you are considering.

Check Mechanical Performance

For shelving, calculate the expected deflection. The supplier can provide the flexural modulus. You provide the span, load, and acceptable deflection. If the calculation shows visible sag, increase thickness before increasing density.

Confirm flatness tolerance. For wall cladding where adjacent panels must align, specify ≤1.5 mm/m flatness. For shelving, ≤2.0 mm/m is typically acceptable. Boards that will be installed edge-to-edge on a visible wall need tighter tolerance than boards that will be cut into shelf-sized pieces.

Plan Logistics and Testing

Separate packaging and freight from the base quote. Rigid boards at 15 to 18mm thickness and 0.55+ density are heavy, a 40HQ container reaches weight limits before volume limits on thick, dense orders. Confirm the container loading plan with your freight forwarder.

Request a sample at the quoted specification. Support it at the span you intend to use, load it to the expected weight, and measure the deflection after 24 hours. A calculation on paper is a starting point. A board on your test bench is the answer.

The Three Cost Factors

Rigid PVC foam board pricing reflects the three factors that produce the rigidity: density (more PVC resin per sheet), thickness (more material volume per sheet, slower extrusion line speed), and product type (Celuka and co-extruded involve additional manufacturing steps beyond free foam).

Density Versus Thickness on Cost

Density and thickness interact on cost. Increasing thickness from 15mm to 18mm increases material volume by 20% at the same density. Increasing density from 0.55 to 0.65 increases PVC resin consumption by approximately 18% at the same thickness. If an 18mm shelf at 0.55 density meets the deflection requirement, it costs less than a 15mm shelf at 0.70, and performs similarly. The optimal specification uses the cheapest combination of density and thickness that satisfies the mechanical requirement, not the highest number in either column.

The Highest-Volume Specification

White Celuka at 15 to 18mm, 0.55 to 0.60 g/cm³, 1220×2440mm, this specification combination has the highest production volume and the best pricing. Custom colors, non-standard sizes, and densities above 0.70 carry higher MOQ and longer lead times.

Confirm the Board Specification

Confirm which product type you need. Celuka for structural applications and screw-holding. Co-extruded for outdoor UV exposure. Free foam for printing at the lowest cost.

Confirm density. Bathroom and kitchen cabinets: 0.55 to 0.65 g/cm³ for screw-holding above 900N (QB/T 5883-2023). Non-structural back panels: 0.45 to 0.50 g/cm³ is sufficient.

Confirm thickness. Cabinet bodies: 15 to 18mm. Door panels: 5 to 10mm. Wall cladding: 8 to 12mm. Cold store liners: 15 to 22mm.

Confirm fire rating. Celuka and co-extruded board are available in B1 (DIN 4102-1, schwerentflammbar) for public buildings and commercial spaces. Free foam is B2 (normalentflammbar). If your project requires a specific fire certificate, specify it at the quote stage.

Outdoor Grade, Edge Sealing, and Logistics

For outdoor applications, do not assume the board is UV-stabilized. Only co-extruded board carries the Shine internal durability classification for outdoor service (up to 8 to 10 years in temperate climates; independent weathering data available on request). Celuka lasts 5 to 7 years in semi-outdoor use. The mechanism is the physical barrier of its hard skin rather than a concentrated UV stabilizer package. For full outdoor exposure, specify the co-extruded grade. Free foam lasts 1 to 2 years. Specify outdoor grade when you inquire.

Separate packaging, freight, and port charges from the base FOB price. Standard PE film is included. Upgraded pallet or crate packaging for ocean freight is at buyer's expense.

Confirm edge sealing requirements. For wet-area applications, cut edges expose the foam cells and must be sealed with PUR edge banding (≥1.5mm thickness) or PVC welding rod.

Request a sample and test it in your application environment before ordering, submerge it, cycle it through hot and cold, expose it to your cleaning chemicals. The data sheet says it works. Your test confirms it.

Facteurs influant sur les prix

Closed cell PVC foam board pricing depends on product type, density, thickness, color, and order volume. Celuka and co-extruded boards cost more than free foam because of the additional manufacturing steps, cooled calibrator tooling for Celuka, twin-extruder setup for co-extrusion. B1 fire-rated formulations require additional flame retardant loading and cost more than B2 (DIN 4102-1) grades.

Density is the primary cost driver within each product type, because higher density means more PVC resin per sheet. For bathroom cabinets, 0.55 to 0.65 g/cm³ balances screw-holding performance with material cost. Using 0.70 g/cm³ where 0.60 would work adds cost without adding value to the end user.

White is the standard production color and the most economical. In contrast, black and custom colors require extruder cleaning and separate runs with higher MOQ.

Foire aux questions

What makes PVC foam board rigid, density or thickness?

Both, but thickness is the stronger lever. Bending stiffness scales with the cube of thickness, an 18mm board is approximately 73% stiffer than a 15mm board at the same density. Density affects stiffness approximately linearly above 0.50 g/cm³. To increase stiffness, add thickness before adding density, because it is more effective and usually more cost-efficient.

Is rigid PVC foam board the same as Celuka board?

Not exactly. Rigid PVC foam board is a performance description, not a board type. All three board types are rigid sheets; the Celuka process produces the best rigidity-to-weight ratio, because flash-freezing the surface against a chilled calibrator creates a dense skin. "Rigid" describes the performance. "Celuka" describes the manufacturing method that produces it. Free foam board can be made rigid by increasing density alone, but it will not match the stiffness of Celuka at the same density because the skin is missing.

How do I calculate whether a shelf will sag?

You need the flexural modulus (E) of the board at the specified density, the shelf dimensions (span L, width b, thickness h), and the expected load (P). For a simply supported shelf with a uniform distributed load, the mid-span deflection is approximately: δ = (5 × P × L³) / (384 × E × I), where I = (b × h³) / 12. Your supplier should provide the flexural modulus for the density and thickness you are ordering. If the calculated deflection is more than L/200 (3mm over a 600mm span), the sag will be visible to the end user.

Can rigid PVC board be used for structural framing?

No. PVC foam board is a panel material, not a structural framing material. Its flexural modulus is roughly one-tenth that of structural timber (8,000 to 12,000 MPa) and about two orders of magnitude below steel (200,000 MPa). Use rigid PVC board as a panel within a frame, not as the frame itself.

How does rigid PVC board compare to plywood for shelving?

Plywood at 18mm is typically stiffer (flexural modulus 8,000 to 10,000 MPa) and stronger. But plywood absorbs moisture, can delaminate in humid conditions, and requires edge banding or painting for a finished appearance. In a dry environment where aesthetics are secondary, plywood is the more rigid and lower-cost choice. In a bathroom, kitchen, or humid climate, PVC board maintains its dimensions and appearance without degradation, plywood does not. The material choice depends on the environment, not just the load calculation.
