Abstract: Disclosed herein is a method for producing a polystyrene foam. The polystyrene is dosed with a gas and the polystyrene and gas are mixed in an extruder in order to obtain a homogenous mixture. The homogeneous mixture is cooled as it travels through the extruder and is then extruded from the die at a pressure of less than 7 MPa to form a foam with a smooth skin.

Abstract: The invention relates to a method for making articles having a veined aspect that includes the steps of (a) extruding a layer of substantially transparent PMMA including pigmented granules in a first extruder, (b) extruding a polystyrene layer including a foaming agent in a second extruder, wherein the extrusions of steps (a) and (b) are carried out simultaneously as a co-extrusion.

Abstract: The invention relates to a method for making a fireproof polymer foam, and to a fireproof polymer foam containing a mixture of a polymer composition containing one or more optionally-substituted, sequenced or random, thermoplastic and/or elastomer homopolymers, copolymers or mixtures thereof, from 0.05 to 10 wt %, preferably from 0.5 to 5 wt %, relative to the mixture, of carbon nanotubes, and from 0.05 to 15 wt %, preferably from 0.5 to 10 wt %, relative to the mixture, of red phosphorus.

Abstract: The invention relates to a method for the continuous, single-step application of a decoration to at least one face of articles made from an extruded- or foamed-plastic material. The aforementioned step comprises: (i) the embossing of at least one face of the article, by passing the article under an embossing roller which is equipped with a relief groove; and (ii) the printing of said at least one face of the article with the transfer of an ink from a composite film with transferable ink. The printing step is performed concomitantly with the embossing step with the same embossing roller which is made form an elastic material and which is heated to the surface softening temperature of the plastic article. The invention also relates to a device for decorating extruded- and foamed-plastic articles in a single step, to the articles thus decorated and to the use of the method and the device.

Abstract: Disclosed is a removable edge guard (10) for installation close to an edge of a vehicle door or the like. The edge guard is made of polymeric material for removable installation on a vehicle door having a trim. The edge guard (10) comprises:—a bumper (12) section and—two planar sections (14), each adjoining said bumper section,—said bumper section (12) comprising a U-shaped portion conceived to bridge said trim of said vehicle door and extending laterally over said edge of said vehicle door,—said planar sections (14) comprising means to removably install said guard on said edge of said vehicle door.

Abstract: The invention provides a moulding of foam synthetic resin for hiding the angle zone between the wall and the ceiling or between the wall and the floor of a room, which to the rear has a retainer profile (7 and 8), into which the lugs (9 and 10) on the fittings (1) fit. The fittings (1) secured in the angle zone between the wall and the ceiling thus bear the moulding (2) and the arrangement in accordance with the invention consisting of the moulding (2) and the fittings (1) may also constitute the border of a suspended ceiling adjacent to the walls and in this respect simultaneously perform a load bearing function as regards the ceiling edge elements of the suspended ceiling. The suspended ceiling may be a coffered ceiling, whose coffer frame are constituted by the mouldings (2). The angles constituted by two respective mouldings of a coffer frame are held together by means of angle fittings or, respectively, resilient staples.
