Seals and walls: minimum 4 mm wide
Keep walls of inlays and edges of gaskets and seals at least 4 mm wide. Anything narrower will deform the foam and prevent the edge from holding its shape.

About Cellular rubber neoprene
About Cellular rubber neoprene
Neoprene closed-cell rubber is a soft foam rubber (CR) with closed cells. Have it custom laser cut for seals, gaskets, vibration dampers, and insulation in enclosures and machinery.
When to choose neoprene closed-cell rubber?
Choose closed-cell rubber if a seal needs to close with low compression force, for example, between a lid and a thin-walled enclosure. The closed cells block water and dust. The material resists oil, fuel, ozone, and UV light, so you can also use it outdoors and in machinery. If the gasket needs to withstand higher pressure or wear, solid CR rubber is the better choice. For firmer inlays, look at PE hard foam.
Laser cutting neoprene closed-cell rubber: what to expect
The laser cuts every contour, including bolt holes and locating pins, without a die-cutter. The cut edge will be slightly darker and may show light black residue. If you want to mount the gasket directly, choose the adhesive layer on the underside: the liner is cut along with it. Because the foam is soft, minimum wall widths apply. You'll find these in the design tips.
Design tips for Cellular rubber neoprene
Dowel Pins: Minimum 4 mm Attachment
To keep dowel pins in place, ensure an attachment of at least 4 mm wide to the component. Use cut holes to precisely align multiple layers.
Factor in the kerf width for small details
The laser vaporises a narrow strip of material. For small details and precise cut-outs, compensate for the kerf width in your design. The value per thickness is listed under the specifications.
Engraved text: minimum 14 pt
Engrave part numbers, labels, or logos directly into the neoprene. Keep text at minimum 14 pt to ensure readability within the foam's cell structure.

Frequently asked questions about Cellular rubber neoprene
Is neoprene foam suitable for watertight seals?
Yes. Neoprene foam has closed cells and absorbs very little water (2% after 3 minutes), so it seals against water, dust, and draughts. For an effective seal, compress it by approximately 25–40%. If the seal needs to withstand high pressure, choose CR sheet rubber, silicone, or gasket paper.
What substances is neoprene foam resistant to?
Neoprene foam is highly resistant to mineral and synthetic oil, grease, brake fluid, ozone, hot and cold water, and UV light. It has limited resistance to petrol, alcohol, and turpentine.
Can cellular rubber neoprene be supplied with an adhesive layer?
Yes, for all thicknesses, you can choose an adhesive film on the underside. The laser also cuts the liner, so your parts are ready to stick immediately. The cut edge remains clean, without adhesive residue, and even fine details remain sharp.
What does the cut edge of neoprene foam look like?
Slightly darker in colour, sharply defined, and it leaves hardly any residue. Cut loss is greater in foam than in hard materials, so parts will be slightly smaller than designed. Account for this when designing mating parts.
Does cellular rubber smell like neoprene?
Slightly: cellular rubber has a rubbery smell, which is barely intensified by laser cutting. Solid CR sheet rubber smells significantly stronger.
Can I get different thicknesses in a single part?
No, we only cut 2D in a single thickness. You create a difference in thickness by stacking layers, for example with an adhesive layer.
When do I choose neoprene foam rubber, and when another material?
Neoprene foam rubber is ideal for seals and for inlays of small, thin parts. For larger inlays and case interiors, PE hard foam or soft foam is better. If a seal needs to withstand high pressure, choose CR sheet rubber, silicone, or gasket cardboard.
Can I see neoprene foam rubber in person first?
Yes, with the Foam, Rubber & Seals sample chain: 6×6 cm laser-cut samples where you can see the cut edge and the kerf.
