METHOD FOR IMPREGNATION A POLYMERIC GRANULATE WITH A PHYSICAL BLOWING AGENT

A method for impregnating a polymeric granulate with a physical blowing agent is disclosed. The polymeric granulate can be a typical material such as a polycarbonate that is used in foam injection moulding processes. The physical blowing agent can be carbon dioxide which impregnates that polymeric granulate at a temperature range of 40 to 120 C. and a pressure range of 15 to 55 bar. Preferably, the polymeric granulate is heated in a range of 50 to 90 with a range of 60 to 80 preferred. A pressure range of 0 25 to 45 bar is preferred with a range of 30 to 40 bar more preferred.

Expanded polymer pellets

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.
