  • 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.
