Silicone rubber

Material Overview

Our silicone rubber sheets are available in transparent (translucent) and red; the red variants are FDA-approved for food safety. This silicone rubber is flexible, elastic, and resistant to temperatures up to approximately 220 °C. What’s important: the material is laserproof, allowing for clean cuts and high-precision engravings.

Silicone rubber is fire-resistant, which makes laser cutting a bit challenging. The residue from the cut appears around the edge in the form of a somewhat greasy black ash. This ash can be easily washed off afterward. If you have many parts, you can place them in a laundry bag and run them through the washing machine.

✔ Ready-to-use – directly applicable in laser cutting machines
✔ Food safe – meets FDA/BfR standards (red)
✔ Temperature resistant – up to approximately 220 °C
✔ Elastic &and wear-resistant – ideal for seals and mats
✔ Cutting width approx.0.2 mm (± 0.05 mm) – precise contours
✔ Fast delivery – standard size 120 × 60 cm, available upon request up to 250 × 120 cm
✔ Engravings have almost the same color as the material but are visible due to relief
✔ No protective film needed – just clean after processing

Which laser source is this material suitable for?

Applications

For hobbyists:
Suitable for layered sculptures, wall ornaments, and model building. Engravings are subtle and can be beautifully detailed with stencils or for relief work.

For professionals:
Widely used in the food, pharmaceutical, and medical industries for seals, closures, baking molds, mats, and gaskets. Also great for technical mats, insulation, damping, and stencils. The elastic properties and food safety make it especially valuable.
