Abstract:
Films or plates made of a plastic mixture and capable of being metal-plated are disclosed, comprising, in relation to the total weight of components A, B, C and D, which add up to 100 % by weight: (a) 5-50 % by weight of a thermoplastic polymer as component A; (b) 50-95 % by weight of a metal powder having an average particle diameter ranging from 0.01-100 µm (determined by the method defined in the description), the metal having a more negative normal potential in an acid solution than silver, as component B; (c) 0-10 % by weight of a dispersant as component C; and (d) 0-40 % by weight fibrous or particulate fillers or their mixtures as component D. The elongation at tear of component A (determined by the method defined in the description) is 1.1-100 times higher than the elongation at tear of the plastic mixture comprising components A, B and optionally C and D (determined by the method defined in the description). The tensile strength of component A (determined by the method defined in the description) is 0.5-4 times higher than the tensile strength of the plastic mixture comprising components A, B and optionally C and D (determined by the method defined in the description). Also disclosed are thermoplastic moulding compounds for producing these films or plates that can be metal-plated, a granulate comprising these thermoplastic moulding compounds, stratified composite films or plates and mouldings comprising these films or plates, metal-plated polymer bodies comprising these films or plates, stratified composite films or plates and mouldings, processes for producing these objects, the use of these objects as EMI shieldings and absorbers, dampers or reflectors for electromagnetic radiation, oxygen scavengers, electroconducting components, gas barriers, and decorative elements comprising these objects.
Abstract:
The invention relates to a dispersion for applying a metal layer to an electrically non-conductive substrate containing an organic binder component, a metal component with different metals and/or metal particle shapes, and a solvent component. The invention further relates to methods for producing said dispersion, methods for creating an optionally structured metal layer with the aid of the dispersion, the obtained substrate surfaces, and the use thereof.
Abstract:
Preparation of metal-plated, extruded plastic comprises: melt blending and extrusion of a plastic mixture (comprising: thermoplastic polymer (A); metal powder (B) having an average particle diameter of 0.1-100 mu m and more negative normal potential in acid solution than silver; dispersant (C); and fibrous/particulate fillers or their mixture (D)); and contacting the extruded plastic object with an acid, neutral or basic metal salt solution through electrolessly or galvanically. Preparation of metal-plated, extruded plastic comprises: melt blending and extrusion of a plastic mixture (comprising 100 wt.% of the components related to the total weight: 5-50 wt.% of thermoplastic polymer (A); 50-95 wt.% of metal powder (B) having an average particle diameter of 0.1-100 mu m and more negative normal potential in acid solution than silver; 0-10 wt.% of dispersant (C); and 0-40 wt.% of fibrous/particulate fillers or their mixture (D)); and contacting extruded plastic object with an acid, neutral or basic metal salt solution through electrolessly or galvanically brought into contact , that metal having a more positive normal potential in a correspondingly acid, neutral or basic solution than component (B), where the plastic object is surface-activated in the non-molten state after the melt blending and extrusion step and before the contacting step. An independent claim is included for a metal-plated, extruded plastic object obtained by the process.
