Bayer Plastics' New Polycarbonate-based Film Is 50X Smoother Than Traditional Matte Textures

Bayer Plastics' Film Business expands its line of polycarbonate films with the introduction of Makrofol DPF 5001. Makrofol DPF 5001's surface design includes a high gloss first surface and a proprietary micro-matte second surface (ca. 0.2 microns), which is 50X* smoother than traditional matte textures. |

Combining the benefits associated with both traditional gloss and matte-textured surfaces, the micro-matte texture offers customers unique attributes such as excellent printability, no need for masking, as well as low internal stress.
The micro-matte design also gives Makrofol DPF 5001's smooth texture a higher surface energy than the traditional gloss surface. 'That higher surface energy provides a printer-friendly surface for screen printing a wide variety of inks,' said Dr. Shu Liu, Product Development Specialist, Bayer Plastics.
The micro-matte surface can be cleared out with a single pass of ink to make automotive display windows. While maintaining good scratch resistance, Makrofol DPF 5001 has a higher total light transmission and a lower haze than traditional matte textured films. By addressing the wear-resistance issue, Makrofol DPF 5001's micro-matte second surface does not require masking, which saves users costs associated with the labor, time, and equipment necessary to remove it from the film.
'This aspect will also help to reduce dustcontamination associated with masking removal,' said Liu. The low internal stress in Makrofol DPF 5001 results in its superior dimensionalstability and excellent graphic registration, which makes it an ideal film for Film Insert Molding (FIM) applications.
Makrofol DPF 5001, primarily designed for the manufacture of automotive instrument display windows, is available in gauges between 0.005' to 0.030'. 'Makrofol DPF 5001 gives display windows, like those used for a car's odometer or clock, a glasslike look,' added Liu. 'In the automotive market, our customers are already incorporating this design in their upcoming models.'
Makrofol DPF 5001 will be manufactured at Bayer Corporation's facility in Berlin, Conn. |
