...s required for heavier currents, the conductive tracks can be made thicker afterwards by electroplating. The most suitable types of film for the substrate material are polycarbonate (grade: Makrofol, manufacturer: Bayer) and (PBT+PC) blends (grade: Bayfol, manufacturer: Bayer). They can be insert moulded with PC or (PC+ABS) blends without using a primer. Complex Structures by Film Pre-forming Work on the technology of insert moulding a plastic film with a conductive track is ongoing, and initi...

... strength and rigidity as well as thermal stability and dimensional accuracy. The industry’s increased requirements on decoration are fulfilled by use of engineering sheets made of polycarbonate (Makrofol) and polycarbonate blends (Bayfol) (Fig. 5), among others. In the IMD (In Mould Decoration) procedure the printed sheets can be injected on the back side using the same material. Thus the print format is protected against scratching and abrasion and colour brilliance is preserved nevertheless [...

The world's largest producers of PC and PC blended films are Bayer MaterialScience (Makrofol and Bayfol) and GE Structure Products (Lexan). A great deal of development work is currently being put into surface finishing of the films. For instance, efforts are being made to make them more resistant to scratching and mechanical loads with hard coats. Another focus is th...

The film: A film composed of a PC/PBT alloy was used for the Gigaset 4000 micro (grade: Bayfol CR1-4, manufacturer: Bayer AG) in an optimised two-layer structure (overall thickness around 300mm incl. printing ink). Essential characteristics of this decorative film are: - uniformly mat surface, - high chemical resistance as well as - good deformability durin...

In this functional elements are integrated into decorated surfaces based on Makrofol DE (PC) or Bayfol (PC blend) without them being permanently visible. By this means switches, controllers and displays can be accommodated in "concealed" fashion in a panel. They only appear when they are activated by finger pressure. At present demand is rising for ...

The investigations were initially carried out with film materials from BayerMaterialScience AG of type Makrofol DE 6-2 (PC) and Bayfol CR 6-2 (PC+PBT) in a thickness of 250µm. Films made of (PC+ABS) blend with the same layer thickness (type: Bayblend T65, manufacturer: BayerMaterialScience) were extruded by way of example. Defined specimens were then taken from injection molded panels...

Bayer MaterialScience AG, Leverkusen, Germany, is therefore currently developing a holographic photopolymer known as Bayfol HX, which is specially tailored for the production of true-color, high-contrast, 3-D image holograms on an industrial scale. This self-developing material could be an attractive alternative to the material classes previously offered, which are expe...

Bayer Material-Science is currently preparing to launch the first photopolymer product grades on the market under the name Bayfol HX. Unlike the materials available at present, these photopolymer films require no subsequent chemical or thermal treatment, which should make them suitable for the cost-effective mass-production of volume holograms. Looking to extend their applic...

By means of volume holography, these PC films permit light management. They are supposed to enable any size of image to be displayed on the windscreen, also with small projectors. In future, the films will be an integral part of the windscreen, thereby using the en...
