Tailor-made for each process step
Böttcher offers a broad range of rubber and polyurethane roller covering compounds, covering practically all areas in the production and converting of plastic film. This range is continually developing and expanding to keep pace with the changing demands of the industry. For example, besides classic rubber compounds for film extrusion, we also manufacture extremely wear-resistant polyurethane coverings. These compounds significantly extend the life of the rollers, thereby having a positive effect on machine up-time and extending the range of different materials, web widths, etc. which can be produced. For PVC processing, e.g. for floor coverings, you can choose from a range of different compounds, depending on your specific requirements in terms of temperature and chemical resistance.
For coating and other finishing processes, BöttcherTec coverings are in use all over the world, thanks to the optimized compatibilty of our coating roller coverings with all types of coating materials. This guarantees even and consistent coating weights across the width of the film and throughout the run, and in many cases, thanks to the resulting dimensional and hardness stability of the roller coverings, enables a reduction in coating weight without detracting from the properties of the finished product. In both flexographic and gravure printing on plastic film, BöttcherTec roller compounds excel with uniform and consistent ink transfer and print quality, whether you are printing solids, screens or both.
