⚙️ CO₂ Laser Applications for Elastomers (Non-Foam)

Precision Cutting and Marking of Rubber and Flexible Polymer Sheets with AEON Laser

CO₂ laser systems are highly effective for processing a wide range of elastomers—flexible, rubber-like materials commonly used in industrial, automotive, and creative applications. CO₂ lasers enable precise, contactless cutting of elastomer sheets with clean edges, complex geometries, and high repeatability. While deep engraving is generally limited, surface marking is possible on select materials.

✅ Why Use CO₂ Lasers for Elastomers?

· Clean, Accurate Cutting
Cuts flexible materials without deformation, fraying, or tool wear—ideal for gasket manufacturing, seals, and custom components.

· Non-Contact Processing
Eliminates mechanical stress, reducing the risk of tearing or material distortion, especially on intricate designs.

· Supports Complex Geometries
Ideal for cutting fine details like holes, slots, curves, and complex gasket outlines.

· Fast Prototyping & Low-Volume Production
No physical dies are needed, offering flexible production for custom orders or fast design iteration.

· Surface Marking on Select Rubbers
Shallow marking is achievable for labeling, part identification, or branding, though contrast depends on the material.

� Elastomers Compatible with CO₂ Lasers (Foams Excluded)

Material	Suitability	Application Notes
Natural Rubber (NR)	✔️ Cut, mark	Widely used for seals and gaskets; cuts well with typical edge darkening; noticeable odor.
Neoprene (CR)	✔️ Cut, mark	Popular in marine, sports, and gasket industries; cuts clean with a moderate odor.
EPDM (Ethylene Propylene Diene)	✔️ Cut, mark	UV- and weather-resistant rubber; common in automotive and roofing; minor charring on edges.
Nitrile Rubber (NBR)	✔️ Cut, mark	Oil-resistant rubber for industrial seals; cuts cleanly with darker edges.
SBR (Styrene-Butadiene Rubber)	✔️ Cut	Economical rubber used in mats, shoe soles, and flooring; cuts well, but edges darken.
Silicone Rubber (solid sheets)	✔️ Cut only	Cuts exceptionally clean; almost no burning; surface marking is shallow with limited contrast.
Viton® / FKM (Fluoroelastomers)	❌ Not suitable	Hazardous: Releases hydrogen fluoride gas when lasered—strictly prohibited.
PVC-Based Rubber Composites	❌ Not suitable	Toxic: Emits chlorine gas; absolutely unsuitable for laser processing.

⚠️ Important Material Safety Notes:

· Strictly avoid:

· PVC-containing rubbers → Chlorine gas risk.

· Viton® / FKM → Emits highly toxic hydrogen fluoride gas.

· Always verify the exact composition of the elastomer before processing.

· Adequate fume extraction is mandatory even for safe rubber types, as natural rubber compounds produce significant smoke and odor.

� Common Business Applications

Industry	Application Examples
Industrial	Custom gaskets, washers, vibration dampeners, seals for machinery
Automotive	Window seals, weatherstripping, under-hood gaskets, rubber spacers
Manufacturing	Conveyor belt guides, impact pads, tool grips
Creative & DIY	Rubber stamps (for natural rubber), custom accessories, art panels
Footwear	Outsoles, midsoles, custom patterned rubber inserts
Crafts & Design	Custom-patterned mats, home decor elements, and creative signage with rubber textures

Pro Tips for Laser Processing of Elastomers

· Air Assist is Crucial: Reduces smoke buildup and improves edge quality.

· High Speed, Moderate Power: Helps reduce edge burning, especially on natural and synthetic rubbers.

· Odor Management: Rubber cutting produces strong odors—use an efficient fume extraction system.

· Test for Marking: Surface marking quality varies—silicone marks lightly, neoprene and EPDM mark better with dark contrast.

· Edge Quality: Expect some natural edge darkening, especially with natural rubber and NBR; this is normal and functional for most industrial uses.
