Abstract: A process for producing foam particles composed of thermoplastic elastomers having polyamide segments, comprising the steps: (a) production of a suspension of pellets of the thermoplastic elastomer in a suspension medium, (b) addition of a blowing agent, (c) impregnation of the pellets with the blowing agent by heating of the suspension in a pressure vessel to an impregnation temperature IMT at an impregnation pressure IMP, depressurization of the suspension by emptying of the pressure vessel via a depressurization device and work-up of the foam particles obtained, and also foam particles obtainable by the process.

Abstract: The invention relates to a method for transporting foamed thermoplastic polymer particles (3) from a container (5, 9) through at least one pipe (7,9), wherein, for transporting the foamed thermoplastic polymer particles (3), a gas stream is applied through the pipe (7, 11). The foamed thermoplastic polymer particles (3) are wetted with a water comprising lubricant.

Abstract: A covering for a truck covers a bottom of the engine compartment, and includes a covering element displaceable from a covering position into at least one further position. A clear opening in relation to a vertical direction of the vehicle is exposed in the at least one further position of the covering element. An additional covering for a driver's cab of the truck can cover the rear of the engine compartment. The additional covering has at least one covering element that is displaceable from a covering position into at least one further position.

Abstract: The invention relates to processes for the production of a composite component via multicomponent injection molding, where the composite component comprises a main body composed of a thermoplastic and an external layer composed of a foamed thermoplastic. The main body is produced via injection molding and subsequent hardening of the thermoplastic. A mixture of the foamed thermoplastic and a chemical blowing agent is injected onto the main body, subsequently hardened in the same injection mold, and foamed by heating. The composite component is solidified via cooling. The foamed thermoplastic is at least one polyamide whose modulus of elasticity is from 1 MPa to 250 MPa in the entire temperature range from 70° C. to 180° C. The chemical blowing agent is in non-polymerized form.

Abstract: A pelletizing die for a pelletizer comprises a base body with holes for melt to pass through; the holes are disposed in rows. Allocated to the holes are wearing-protection inserts, having holes which are in alignment with the holes in the base body. The inserts which are disposed to adjoin each other in a row have a chordal surface where they are turned toward an adjoining insert and are provided with at least one surface of an arcuate segment of a cylinder laterally of the chordal surface.
