New Surface Protection Film for Laser Cutting

Novacel, a specialist in industrial surface protection, has launched Novacel 4226REN, a highly innovative protection film for sheet metal. 4226REN reduces laser-cutting time and will maintain surface integrity while parts are being cut and in other operations where parts are subjected to bending, backing, stamping or forming.

Novacel 4226REN is a white-on-white film, with six month outdoor resistance. The film is made of a 3.9 mil, UV resistant, LDPE (low-density polyethylene). The product uses a highly specialized, rubber-based adhesive providing 12.8 ounces/inch adhesion (AFERA 4001 test method). The 4226REN product is available in lengths of 3281 feet or 1641 feet.

Novacel 4226REN permits protected sheet metal to be laser cut in a single run. There is no peel back and no formation of air bubbles during laser-cutting operations. Additionally, no black marks are left on stainless steel after laser cutting. The film can be removed in one piece without blocking or tearing. Novacel 4226REN features a unique print: The print shows the potential for single-run, metal laser cutting and the brushing or polishing direction.

The film’s specific pattern permits automated sheet-metal handling (with the surface protection applied) and prevents multiple sheet feeding due to suction between the sheets. The film acts as a protective barrier (preventing scratches or other damage) through all converting processes (folding, stamping and profiling) and during handling, transport and fitting.
