  • Publication number: 20210023748
    Abstract: The invention relates to a method for producing a moulded part (50) by structural foam moulding, in which a polymer melt (18) is provided by melting a thermoplastic material, in which the polymer melt (18) is charged with a foaming agent (22) and in which the polymer melt (18) charged with the foaming agent (22) is injected under pressure into a cavity (26) of a mould (28), and so the polymer melt (18) fills the cavity (26) behind a melt front (34) running through the cavity (26), wherein the rate of injection at which the polymer melt (18) is injected into the cavity (26) of the mould (28) is set such that the internal pressure of the polymer melt (18) in the cavity (26), in a region (40) that follows a portion of the melt front (34) with a time delay of at most 0.15 seconds, is greater than the critical pressure of the foaming agent (22), at least at one point in time during the injection-moulding operation.

  • Publication number: 20140356551
    Abstract: The invention relates to thermoplastic compositions comprising A) 30.0 to 100.0 parts by wt. of at least one aromatic polycarbonate, B) 0.0 to 50.0 parts by wt. of a rubber-modified graft polymer and/or vinyl copolymer, C) 0.00 to 50.00 parts by wt. of polyester, D) 5.0 to 50.0 parts by wt. of at least one inorganic filler having a particle shape selected from the group including spherical/cubic, tabular/discus-shaped and lamellar geometries, and E) 0.00 to 5.00 parts by wt. of further conventional additives. The invention further relates to thermoplastic shaped articles having a high surface quality, high dimensional stability and high heat distortion temperature, as well as thermoplastic moulding compositions and a process for the production of the shaped articles. The present invention moreover relates to the coated finished parts produced from the thermoplastic shaped parts.

  • Publication number: 20140329071
    Abstract: The invention relates to multilayer structures made of at least one thermoplastic material and having at least one metal layer. The invention further relates to multilayer products encompassing at least three layers comprising a substrate layer made of a substrate comprising specific copolycarbonates and at least one inorganic filler, a metal layer and one or more further layers. The invention further relates to the process for producing the said multilayer structures.
