<p>The present invention relates to semi-finished products in sheet or surfacing foil form for producing thermoplastic coatings with particular properties on finished parts produced by thermoforming or molding-stamping thermoplastic materials in plate or sheet form. These are constituted by: a basic mixture comprising 15%-95% by weight of reinforcing fiber, 85%-5% by weight of powder of at least one thermoplastic material, and, relative to this mixture, 2%-20% by weight of polyolefine dough, 1%-30% by weight of a binder, 0.2%-10% by weight of at least one floculant and if necessary a dispersing agent. These surfacing foils are characterized in that they contain: from 30 to 90% by weight of at least one polyolefine dough, from 2 to 15% by weight of binder, from 0.5 to 5% by weight of at least one floculant, the rest of the materials being composed of at least one powder element selected from among thermoplastics, fillers and pigments.</p> |
