Bi-component filaments with customized function
Integration of functions
Bi-component monofilaments: individually functionalized
Our extrusion technology enables the co-extrusion of high-tech monofilaments from two different plastics in core and sheath. This makes it possible to functionalize the monofilaments in specific ways. The two thermoplastic polymers are selected to produce specific properties that can fulfill individual customer requirements.
For the manufacture of aluminum windows, for example, we produce the adhesive ribbon. For thermal insulation, aluminum windows are fitted with interior plastic insulation strips, which need to be joined. This is where our adhesive ribbon comes into play. The ribbon is a bi-component filament with a core made of polyamide 6.6 GF25% and a hot-melt adhesive sheath. In the coating process (powder coating at temperatures between 180 and 230°C), the adhesive function of the adhesive ribbon is activated after cooling. The aluminum profile and the plastic strip are thus firmly connected and all cavities (capillaries) are filled.
Also for 3D printing
Our bi-component filaments also present interesting application potentials in filament-based 3D printing. Various material combinations of thermoplastics, additives and fillers in the core and sheath can be used to alter the characteristics of the printed product in specific ways (e.g. fire-resistance, chemical resistance, breaking strength, heat resistance). This is particularly important for functional parts and for prototypes.
