Abstract: A method for producing a molded part, in particular a component of a sporting good, includes providing a mixture of a polymer melt and a foaming agent and injecting the mixture into a mold. The method includes solidifying at least a first portion of the molded part without foaming and at least a second portion of the molded part after foaming inside the mold, wherein the mixture includes a polymer having an average molecular mass corresponding to a viscosity number 130 ml/g, preferably 170 ml/g, more preferably 190 ml/g and most preferably 225 ml/g, wherein the viscosity number is determined via solution viscometry according to the ISO 307 standard.

Abstract: The present invention relates to sports balls. A sports ball comprises a surface layer comprising a plurality of panels. The sports ball further comprises a lattice structure extending below the surface layer, wherein the lattice structure comprises a plurality of lattice cells comprising radially extending elements. The lattice cells which are adjacent to the surface layer have at least one dimension which is smaller than an average diameter of the panels.

Abstract: The invention refers to a method for producing expanded polymer pellets, which comprises the following steps: melting a polymer comprising a polyamide; adding at least one blowing agent; expanding the melt through at least one die for producing an expanded polymer; and pelletizing the expanded polymer. The invention further concerns polymer pellets produced with the method as well as their use, e.g. for the production of cushioning elements for sports apparel, such as for producing soles or parts of soles of sports shoes. A further aspect of the invention concerns a method for the manufacture of molded components, comprising loading pellets of an expanded polymer material into a mold, and connecting the pellets by providing heat energy, wherein the expanded polymer material of the pellets or beads comprises a chain extender. The molded components may be used in broad ranges of application.
