Abstract: A process for the manufacture of profiles of cellular thermoplastic material and a device for carrying out this process. This improved process comprises pressing the thermoplastic material containing a blowing agent through a multiple orificed die plate, the orifices of which enlarge in the direction of the material flow, in such a way that they unite at the latest at the outlet side of the die plate. This process ensures excellent welding of the individual elongated elements issuing from the orifices of the die plate.

Abstract: The invention provides foamed plastics particles having a star-like shape the three legs of which are on the same plane. The ratio of particle thickness to particle height is from 1:2.75 to 1:3.3, that of leg width to particle height is from 1:2.2 to 1:2.5, and the particle height is from 10 to 60 mm. The particles of the invention are suitable as free-flowing packing material having a good flow and simultaneously a good interlocking capacity.
