Makrofol HF Polycarbonate Films

For Applications in Automotive Interiors, Electronics and IT

Covestro, formerly Bayer MaterialScience, has developed scratch-resistant, formable hardcoat films named Makrofol HF for the decorative design of component surfaces in automotive interiors.

Apart from automotive interior design, Covestro also sees opportunities for Makrofol HF in consumer electronics, IT equipment and in combination with printed polymer electronics (figure: Covestro)

After high-gloss films with a piano finish proved successful, the use of matte film grades is now on the rise. Makrofol HF polycarbonate films range from matte, finely textured surfaces with a high level of diffusion, to glare-free films and deep matte grades. At an angle of 60°, these matte products display a gloss level of just 1.9 units when backprinted black. The finely textured matte films achieve gloss levels between 70 and 75 under the same conditions.

Matte films can easily be printed, formed or back-injected in a film insert molding process, just like their high-gloss counterparts. The good formability, even with small radii of curvature and high depth of draw, are due to the special coating layer, which is based on a dispersion coating that is only pre-cured. The forming process precedes final curing with conventional UV lamps. The three-dimensional crosslinking of the coating lends the films their high scratch and abrasion resistance; the films are also resistant to sun protection products and chemicals.

With the help of these pre-cured films, manufacturers can produce quality interior components with three-dimensional matte and scratch-resistant surfaces, and still dispense with the costly and complex coating step. In addition to using Makrofol HF in automotive interior design, for instance for side fascia, Covestro also sees opportunities for its application in consumer electronics, IT equipment and in combination with printed polymer electronics.
