Multitec Short Fiber Spraying applied to the back of a thermoformed thermoplastic film provides the necessary stabilization thanks to the addition of glass fibers to the polyurethane.
Traditional casting methods for producing elastomer-coated rollers are stretched to the limit if very large roller cores or very thick coatings are required, for example in the paper industry. In such cases, direct rotational coating using the Bayer MaterialScience one-pass technology and Baytec casting elastomer is the method of choice. And it has its advantages for coating small rollers too, given that it works very economically and produces roller surfaces of particularly high quality.
The company has also made a breakthrough in the development of three-dimensional plastic parts with photorealistic decorative features. This was achieved using a tailor-made film structure consisting of a digitally printable polycarbonate film from the Makrofol range and a special second film which is laminated onto the first. The resultant composite can then be thermoformed and back-injected with plastic. This technology opens the way for decorative features in resolutions comparable with offset printing.
The single-frame radiator grille of the new Audi A6 sets design trends for the front section of cars. Makroblend DP 7645 – a new blend of polycarbonate and polyethylene terephthalate (PC/PET) – is used in the manufacturing process. It offers designers great freedom and used in the manufacturing process. It offers designers great freedom and a whole host of other impressive properties. One key benefit worth highlighting is the outstanding low-temperature impact strength – a key prerequisite for the protection of pedestrians. In spite of its high stiffness, the material is also tough enough to come through most minor accidents unscathed.
