The German SME utilises a recycling process to produce tungsten containing nanopowders in high quality on an industrial scale. The technological process is specifically designed to produce dedicated metal and ceramic nanopowders directly from (hard) metal scrap. The nanopowder variety ranges from pure tungsten to tungsten carbide, tungsten trioxide and premium powder mixtures with selected rare earth elements. The key features of the nanopowders are particle sizes in the nanometer range, relatively high specific surface area values and a high potential of physical, chemical and biological activity. This combination of characteristics make the powders unique for a broad range of technological applications.
In addition, the company is continuously developing novel materials and processing techniques for industrial applications. Thereby, the German enterprise has successfully developed functional additives in the form of viscous pastes, in which tungsten containing nanopowders are finely and homogeneously dispersed in poly-/vinyl ester resins. These functional additives are proved to significantly enhance multiple properties (e.g. mechanical and thermal) of fibre-reinforced plastic (FRP) products from renowned medium-sized European companies. In addition to the technical product improvements, a reduction of material and processing costs of up to 50% was reported by the customers. The additives are fully compatible with state-of-the-art processing technologies in the FRP industry, such as the fiber spraying, wrapping and pultrusion method.
A technical study in cooperation with a medium-sized European company has shown that the functional additives can be easily involved in the pultrusion fabrication process as well. This novel approach enables a highly efficient production of technical plastic profiles with complex geometries and significantly enhanced mechanical (e.g. bending strength and interlaminar shear strength) and thermal properties (e.g. glass transition temperature). Furthermore, the technical plastic profiles maintain their elasticity and form stability after the manufacturing process by pultrusion.
The company is interested in projects and long-term partnerships in the form of technical cooperation agreements and manufacturing agreements as outlined in the section “Type and Role of Partner sought”.
