Abstract: A method for compounding a plastic material is provided, wherein the following steps are carried out: a) providing at least one ethylenic polymer; b) addition of at least one cross-linking agent to the ethylenic polymer; c) at least partial cross-linking of the ethylenic polymer by the cross-linking agent; d) addition of at least one propylenic polymer to the product obtained in step c); and e) at least partial cross-linking of the propylenic polymer with the product obtained in step c). Further, a plastic material producible by this method, and a plastic product made out of it are provided.

Abstract: A device for removing an oblong burr from a molded part including an energy source that introduces energy into the burr for removing the burr by heating. The energy source includes an infrared transmitter that irradiates the oblong burr with infrared radiation, a sleeve for receiving the infrared transmitter with an inner face facing the infrared transmitter and an outer face remote from the infrared transmitter, and an outlet region through which energy may be transported in the direction of the burr. The sleeve has an outer coating with a surface facing the outside, and an inner face facing the infrared transmitter which at least partially encloses the sleeve. Infrared radiation emitted by the energy source is concentrated by a radiation-forming element, so that only the burr is irradiated by the infrared radiation. The radiation-forming element may be formed by a gap in the outer coating.
