Bayer MaterialScience LLC has developed a scratch-resistant polycarbonate film that is thermoformable, weather-resistant and durable.
Makrofol SR 906 is a clear, transparent film with a glossy surface finish. Bayer caps the film with a functional acrylic layer that includes a UV-protective additive. The company claims the film offers a 50 percent scratch resistance improvement over glossy PC films.
The new product is suited to use in information technology and electrical/electronic components as well as auto interior parts such as bezels, knobs and switches. Its versatile aesthetics can create appearances ranging from high-gloss, piano black effects to velvet and graphics-friendly, very fine matte surfaces obtainable with an optional finish.
Bayer says it aims the new Makrofol at OEMs and Tier 1 suppliers, especially those that use a film insert process exposing the film to high forming pressures. The acrylic cap layer allows back-molding or over-molding with acrylic resins as well as standard PC resins often used on the PC film side. High film-to-resin adhesion helps the film pass typical climate test conditions for auto interiors.
“Makrofol SR 906 film enables the manufacturer to use a scratch- and weathering-resistant film to manufacture formed 3-D parts and eliminate secondary coating operations,” notes Chris Cooper, specialty films business development manager for the company based in Pittsburgh.
