Foam PVC (commonly Foamex, Forex or Komatex) is a closed-cell expanded PVC sheet used as the default substrate for signage, display, exhibition stand work, light architectural cladding and short to medium-life outdoor signage. It is light, dimensionally stable, screen-print friendly, and CNC-routes to a clean edge with no chipping. P&M Plastics fabricates Foam PVC for sign makers, exhibition companies and shop fitters every week.

Sizes and formats we stock

Foam PVC sheet is stocked in 1mm, 2mm, 3mm, 5mm, 6mm, 8mm, 10mm, 13mm and 19mm in standard 2440 x 1220mm and 3050 x 1530mm sizes. The 5mm and 10mm thicknesses are the workhorse grades for most signage work.

Colours and grades

White is the standard colour for printed signage and exhibition work. Black, grey, red, blue, yellow and green are stocked for direct-coloured displays and architectural panels. Premium grades include high-density Foam PVC for thicker dimensional signage and lower-density grades for ultra-light exhibition builds.

Foam PVC compared to MDF and acrylic

Compared to MDF, Foam PVC is moisture-resistant, can be used outdoors for several years, and weighs about half as much for the same thickness. MDF is stiffer in larger panels and accepts a paint finish more cheaply, so it remains the right pick for indoor architectural work and shop fitouts where weight and moisture are not concerns. Compared to acrylic, Foam PVC is not transparent, but is far cheaper, easier to cut and easier to print on directly.

Why P&M Plastics for Foam PVC work

We CNC route Foam PVC to client-supplied artwork files (DXF, DWG, AI, SVG, PDF) for dimensional signage, exhibition pieces, shop fit-outs, free-standing letters and architectural cladding. Edges machine to a finished look without secondary processing and the surface takes ink, paint, vinyl and adhesives without surface preparation.

How We Fabricate Foam PVC

We fabricate Foam PVC using CNC routing for sharp clean edges, CO2 laser cutting for fine detail, V-grooving for folded signage and panel construction, and screwing or stapling for assembly. The sheet drills, screws and bonds easily; PVC-rated solvent cement gives the cleanest visible joint. Surface accepts most signage paints, inks and adhesive vinyls without surface preparation.

Frequently Asked Questions

Can Foam PVC be used outdoors? +

Yes. Foam PVC has good UV resistance and holds up well for 3 to 5 years of outdoor exposure, which makes it the standard for short to medium-life signage, real estate signs, event signage and temporary outdoor displays. For permanent outdoor signage (10+ years) step up to acrylic or aluminium composite panel.

What is the difference between Foamex, Forex and Komatex? +

All three are brand names for the same product class: closed-cell expanded PVC. There are minor differences in density, surface finish and colour range between brands, but for most signage and display work the brands are interchangeable. We will recommend the right grade for your application at quote time.

Can Foam PVC be printed on directly? +

Yes. Foam PVC accepts solvent, eco-solvent, UV and latex direct printing without primer or surface preparation, which is why it is the default substrate for most large-format printed signage and exhibition graphics.

Will Foam PVC sag in heat or sun? +

Foam PVC is dimensionally stable up to around 60°C, which covers most Australian outdoor signage applications. Above 60°C the sheet can soften and sag, so for any sign mounted in front of dark surfaces or in full sun the sheet should be specified at 5mm or thicker, with adequate support frames.

Can I screw or nail into Foam PVC? +

Yes. Foam PVC takes screws, nails and staples directly without pre-drilling. For load-bearing work (mounting heavy letters or panels) we recommend pre-drilling and using countersunk screws with a small backing washer to spread the load.

What thickness Foam PVC do I need? +

Most printed signage uses 3mm or 5mm. Free-standing dimensional letters and panels use 10mm to 19mm. Light architectural cladding goes from 6mm to 10mm depending on panel size and fixing centres. Send us the project and we will recommend a thickness.

Can I get Foam PVC cut to a logo or letter shape? +

Yes. Our CNC routers cut Foam PVC to any 2D shape from a vector file (DXF, DWG, AI, SVG, PDF). Most logo and letter jobs are quoted and cut within 24 to 48 hours.
