Neoprene foam rubber

Neoprene foam (also known as neoprene cellular rubber) is a flexible, closed-cell material that is waterproof and does not absorb liquids. It is resistant to seawater, flame-retardant, and fairly oil-resistant, making it ideal for marine and offshore applications, seals, sound insulation, and technical engineering. Thanks to its closed-cell structure, it leaves clean edges without residue after laser cutting, although thin and long shapes may deform slightly due to internal stress.

✔ Highlights

✔ Laser-compatible – clean cuts without residue
✔ Water- and oil-resistant – suitable for demanding applications
✔ Flame-retardant – a safe choice for various applications
✔ Impact-resistant and flexible – conforms easily to shapes
✔ Kerf width approx. ± 0.2 mm – delivers precise contours
✔ Subtle engraving contrast, uniform color
✔ Edges retain the same color and texture as the surface
