Novacel 4228 REF: The High-Speed Fiber Laser Specialist
Redefining Precision for the Next Generation of Fiber Lasers. As metal fabrication moves toward faster, higher-intensity Fiber Laser systems, standard protection films can no longer keep up. Novacel 4228 REF is the specialized solution designed to meet this challenge head-on. Engineered with a unique, gray-tinted polyethylene and a high-performance adhesive, the 4228 REF allows for high-speed piercing and cutting without the lifting, bubbling, or "flame-up" associated with general-purpose films.
When your production schedule depends on the speed of a Fiber Laser, Novacel 4228 REF ensures your machine runs at peak efficiency while your metal stays pristine.
Why Novacel 4228 REF is the Fiber Laser Standard:
Optimized Fiber Absorption: Specifically tuned to the 1.06-micron wavelength of fiber lasers. This allows the beam to pass through the film and pierce the metal cleanly in a single pass, significantly reducing "burr" and secondary cleaning.
Superior "No-Lift" Adhesion: Formulated with a specific peel strength that resists the high-pressure assist gases used in fiber cutting. The film stays flat to the sheet, ensuring the laser head never catches on a "bubble" or loose edge.
Integrated Arrow Graphics: Features directional printing on the film surface, allowing your shop team to easily identify grain direction—essential for consistent fabrication on brushed stainless and aluminum.
Clean-Room Performance: Provides a 100% residue-free peel, even after the high-heat cycles of intensive nesting. Your parts go from the laser bed to the shipping crate with zero chemical wipe-down required.
The Industrial Applications Advantage:
As the Northwest’s technical partner, we don't just sell rolls; we provide the film that saves your laser operator time and your company money.
Master Roll Stocking: We maintain local inventory of 4228 REF in 48" and 60" widths to match standard industrial sheet sizes.
Reduced Downtime: High-quality Novacel film means fewer "head crashes" and lens contamination issues caused by film melting or lifting.
Primary Applications:
Fiber Laser Cutting: The gold standard for high-wattage Fiber systems.
CO2 Laser Cutting: Fully compatible and effective for traditional CO2 setups as well.
High-Finish Stainless Steel: Ideal for #4 brushed and #8 mirror finishes where surface integrity is non-negotiable.
