  • Patent number: 11772369
    Abstract: A multi-layer composite in the form of a hollow body enclosing an interior space (2) is proposed, consisting of three or four layers: an inner layer (3) adjoining the interior space (2), a middle layer (4) adjoining the latter and an outer layer (5) adjoining the middle layer (4) and closing the multi-layer composite (1) to the outside. If necessary, there is a further innermost layer (8) which directly adjoins the said inner layer (3) and is equipped with a conductive finish. The inner layer (3) is based on polyamide 6, the middle layer (4) is based on EVOH, and the outer layer (5) is based on a mixture of (A) polyamide 6 and (B) at least one other polyamide selected from the following group: polyamide 612, polyamide 614, polyamide 616 and polyamide 618.

  • 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.
