Which Plastics Can Be Processed With CO2 Laser?

CO2 lasers are versatile tools for processing a wide range of plastic materials due to their ability to efficiently absorb the 10.6-micrometer wavelength of CO2 lasers. However, the success of processing depends on factors such as the type of plastic, its thickness, and any additives or coatings. Here are common plastics that can be processed with CO2 lasers:

Acrylic (PMMA): CO2 lasers are widely used for cutting, engraving, and etching acrylic sheets. This material is popular for signage, displays, and artistic creations.

Polyester (PET): PET plastics, including PETG, can be cut and engraved with CO2 lasers. They are commonly used for labels, signs, and packaging materials.

Polycarbonate (PC): CO2 lasers are effective for cutting and engraving polycarbonate, which is used in applications like nameplates, protective screens, and instrument panels.

Polyethylene (PE) and Polypropylene (PP): While CO2 lasers are less effective on low-density polyethylene (LDPE), they can be used for high-density polyethylene (HDPE) and polypropylene (PP) materials.

ABS (Acrylonitrile Butadiene Styrene): CO2 lasers can cut and engrave ABS plastics, making them suitable for prototyping and product branding.

Foam Boards: Expanded PVC foam boards and foam-core materials are frequently processed with CO2 lasers for applications like signage, displays, and modeling.

PVC (Polyvinyl Chloride): PVC sheets and vinyl materials can be cut and engraved with CO2 lasers, commonly used for signs, labels, and decorative elements.

Nylon: CO2 lasers can process nylon materials, although they may require specialized settings due to nylon’s higher melting point. Laser cutting and engraving are often used in nylon fabric and film applications.

Polyurethane (PU): Polyurethane materials can be engraved and cut with CO2 lasers, making them useful in industries like automotive and footwear.

Polystyrene (PS): CO2 lasers can cut and engrave polystyrene materials, which are used for applications like model making and architectural prototypes.

Rubber: Certain types of rubber, such as silicone rubber and EPDM, can be engraved and cut with CO2 lasers for gasket manufacturing and rubber stamp production.

Other Specialty Plastics: CO2 lasers can also process various specialty plastics used in industries like electronics, packaging, and medical devices. However, it’s important to test and optimize laser settings for specific plastic compositions.

Always consult the material’s datasheet or conduct tests to ensure that the plastic you intend to process with a CO2 laser is suitable for your application. Additionally, adhere to safety guidelines and proper ventilation when using lasers for plastic processing.
