  • Publication number: 20210032466
    Abstract: The invention relates to the use of thermoplastic polyamide molding compounds to reduce the formation of solid deposits and/or coatings on tools used in thermoplastic shaping to form useful objects in discontinuous processes, in particular in injection molding, and used in continuous processes such as extrusion to form films, fibers, tubes and casings. The molding compounds used are based on polyamides which are largely based on the polyamide units (616, 516) or (916). By virtue of the use of the polyamide molding compounds according to the invention, the solid deposits and/or coatings that otherwise commonly occur in the further processing of polyamide (12) during injection molding or during extrusion, are greatly reduced or prevented.

  • Patent number: 10440832
    Abstract: A method for producing a laser-structurable component, wherein an extruded single- or multilayer molded part with at least one laser-structurable layer that forms an exposed surface of the molded part is applied onto the surface of a non-laser-structurable support element. Alternatively, the at least one laser-structurable layer may be back-molded with a non-laser-structurable thermoplastic support element so that at least one laser-structurable layer of the molded part forms at least one part of the surface of the laser-structurable component. The extruded single- or multilayer molded part is deep-drawn into the component. In the process, the laser-structurable layer of the molded part consists of a thermoplastic molding compound consisting of: (A) 30-99.9 wt. % of a thermoplastic consisting of polyamide; (B) 0.1-10 wt. % of an LDS additive; and (C) 0-60 wt. % of an additive material which is different from (A) and (B).
